- Update to 0.10.2
* This release includes numerous bug fixes and improvements, with
major changes such as a substantial reorganization of the
documentation into a User Guide and Reference Manual, more
consistent and complete docstrings, and support for referencing
signals and subsystems by name as well as by index. Phase plane
plots now use matplotlib’s streamplot for better visuals. New
functions include combine_tf and split_tf for MIMO/SISO
conversion and disk_margins for stability analysis. Additional
improvements include consistent keyword usage, expanded LTI
system methods for plotting and responses, better error
messages, and legacy aliases to maintain backward
compatibility.
* This version of python-control requires Python 3.10 or higher,
NumPy 1.23 or higher (2.x recommended), and SciPy 1.8 or
higher.
## New classes, functions, and methods
* find_operating_point: this function replaces (with a legacy
alias) the find_eqpt function and now returns an
OperatingPoint object containing the information about the
operating point.
* combine_tf and split_tf: these two new functions allow you to
create an MIMO transfer function from SISO transfer functions
and vice versa.
* create_statefbk_iosystem now allows the creation of state
feedback controllers using a “reference gain” pattern (u =
k_\text{f}\, r - K x) in addition to the default “trajectory
generation” pattern (u = u_\text{d} - K(x - x_\text{d})).
* disk_margins: compute disk-based stability margins for SISO
and MIMO systems.
* model_reduction: allow specific states, inputs, or outputs to
be either eliminated or retained.
* place_acker: renamed version of acker (which is still
accessible via an alias).
## Bug fixes
* phase_plane_plot: fixed a bug in which the return value was
returning a sublist of lines rather than just a list of lines
in cplt.lines.
* Processing of the timebase parameter (dt) for I/O systems is
now handled uniformly across all I/O system factory functions.
This affected the zpk function, which was defaulting to a
discrete time system to have timebase None instead of 0.
* Multiplying (*), adding (+), or subtracting (-) a constant
from any (MIMO) LTI object now acts element-wise (same as
ndarray’s). This fixes a bug where multiplying a MIMO LTI
system by a constant was multiplying by a matrix filled with
the constant rather than a diagonal matrix (scaled identity).
* Fixed a bug where specifying an FRD system with fewer than 4
frequency points was generating an error because the default
settings try to set up a smooth (interpolating) response and
the default degree of the fit was 3.
* Fixed some bugs where computing poles and zeros of transfer
functions could generate spurious error messages about unsafe
casting of complex numbers to real numbers.
* TimeResponseData.to_pandas: multi-trace data (e.g., the output
from a MIMO step response) was not being processed correctly.
A new column ‘trace’ is now generated for multi-trace
responses.
* Fixed a bug where where some arguments to nyquist_plot were
not being processed correctly and generated errors about
unrecognized keywords.
* Updated ctrb and obsv to handle 1D B or C matrix correctly.
* bode_plot: Fixed missing plot title when display_margin
keyword was used.
* singular_values_plot: color cycling was not working correctly
when a list of systems or responses was provided.
* nyquist_plot: The lines parameter of the ControlPlot object
now matches the documentation. A 2D array is returned with the
first index corresponding to the response (system) index and
the second index corresponding to the segment type (primary,
mirror x unscaled, scaled).
* Fix some internal bugs that cropped up when using NumPy 2.3.1
but were latent prior to that.
## Improvements
* User documentation is now divided into a User Guide that
provides a description of the main functionality of the
python-control package, along with a Reference Manual
describing classes, functions, and parameters in more detail.
* Signal responses and I/O subsystem specifications can now use
signal names in addition to indices to get the desired inputs,
outputs, and states (e.g., response.outputs['y0', 'y1']). This
is implemented via a new NamedSignal object, which generalizes
numpy.ndarray.
* find_operating_point (legacy find_eqpt): accepts new
parameters root_method and root_kwargs to set the root finding
algorithm that is used.
* root_locus_map now correctly handles the degenerate case of
being passed a single gain.
* The PoleZeroData object now takes a sort_loci parameter when
it is created, with a default value of True. This is useful if
you create a PoleZeroData object by hand (e.g., for producing
stability diagrams).
* Factory functions for I/O system creation are now consistent
in terms of copying signal/system names, overriding
system/signal names, and converting between classes.
* The tf factory function to allow a 2D list of SISO transfer
functions to be given as a means of creating a MIMO transfer
function (use the new combine_tf function).
* The nlsys factory function can now create a NonlinearIOSystem
representation of a StateSpace system (passed as the first
argument to nlsys).
* LTI systems now have member functions for computing the
various time responses and generating frequency domain plots.
See LTI.to_ss, LTI.to_tf, LTI.bode_plot, LTI.nyquist_plot,
LTI.nichols_plot and LTI.forced_response,
LTI.impulse_response, LTI.initial_response, LTI.step_response.
* String representations of I/O systems (accessed via repr,
print, and str) have been updated to create a more consistent
form and provide more useful information. See Displaying LTI
System Information for more information.
* Binary operations between MIMO and SISO functions are now
supported, with the SISO system being converted to a MIMO
system as if it were a scalar.
* nyquist_response: generates an error if you force the system
to evaluate the dynamics at a pole.
* phase_crossover_frequencies: turned off spurious warning
messages.
* ss2tf: added new method=scipy capability, allowing ss2tf to
work on MIMO systems even if Slycot is not present.
* flatsys.solve_flat_optimal (legacy flatsys.solve_flat_ocp):
allows scalar time vector.
* Improved checking of matrix shapes and better error messages
in state space factory functions and other operations where
matrices are passed as arguments.
* FrequencyResponseData: use complex to access the (squeeze
processed) complex frequency response (instead of the legacy
response property) and ~FrequencyResponseData.frdata to access
the 3D frequency response data array (instead of the legacy
fresp attribute).
* Time response and optimization function keywords have been
regularized to allow consistent use of keywords across related
functions:
- Parameters specifying the inputs, outputs, and states are
referred to as inputs, outputs, and states consistently
throughout the functions.
- Variables associated with inputs, outputs, states and time
use those words plus an appropriate modifier: initial_state,
final_output, input_indices, etc.
- Aliases are used both to maintain backward compatibility and
to allow shorthand descriptions: e.g., U, Y, X0. Short form
aliases are documented in docstrings by listing the
parameter as long_form (or sf) : type.
- Existing legacy keywords are allowed and generate a
PendingDeprecationWarning. Specifying a parameter value in
two different ways (e.g., via long form and an alias)
generates a TypeError.
* phase_plane_plot: makes use of the matplotlib streamplot
function to provide better default phase plane diagrams.
* root_locus_plot: added by the ability to recompute the root
locus when zooming in on portions of the root locus diagram.
* nyquist_plot: updated the rescaling algorithm to use a more
gradual change in the magnitude of the Nyquist curve. The
blend_fraction parameter can be used to start the rescaling
prior to reaching max_curve_magnitude, giving less confusing
plots. Some default parameter values have been adjusted to
improve Nyquist plots.
## Deprecations
* The following functions have been newly deprecated in this
release and generate a warning message when used:
* FrequencyResponseData.response: use
FrequencyResponseData.complex to return the complex value of
the frequency response.
* FrequencyResponseData.fresp: use FrequencyResponseData.frdata
to access the raw 3D frequency response data array.
* The listed items are slated to be removed in future releases
(usually the next major or minor version update).

- Update to version 0.9.0
* Version 0.9.0 of the Python Control Toolbox
(python-control) contains a number of enhanced features
and changes to functions. Some of these changes may
require modifications to existing user code and, in
addition, some default settings have changed that may
affect the appearance of plots or operation of certain
functions.
* Significant new additions including improvements in the
I/O systems modules that allow automatic interconnection
of signals having the same name (via the interconnect
function), generation and plotting of describing functions
for closed loop systems with static nonlinearities, and a
new optimal control module that allows basic computation
of optimal controls (including model predictive
controllers). Some of the changes that may break use code
include the deprecation of the NumPy matrix type (2D NumPy
arrays are used instead), changes in the return value for
Nyquist plots (now returns number of encirclements rather
than the frequency response), switching the default
timebase of systems to be 0 rather than None (no
timebase), and changes in the processing of return values
for time and frequency responses (to make them more
consistent). In many cases, the earlier behavior can be
restored by calling use_legacy_defaults('0.8.4').
New Features:
* Optimal control module, including rudimentary MPC
control (#549 by murrayrm)
* Describing functions plots (#521 by murrayrm)
* MIMO impulse and step response (#514 by murrayrm)
* I/O system improvements:
* linearize() retains signal names plus new interconnect()
function (#497 by murrayrm)
* Add summing junction + implicit signal interconnection (#517
by murrayrm)
* Implementation of initial_phase, wrap_phase keywords for
bode_plot (#494 by murrayrm)
* Added IPython LaTeX representation method for StateSpace
objects (#450 by roryyorke)
* New dynamics() and output() methods in StateSpace (#566 by
sawyerbfuller)
* FRD systems can now be created from a discrete time LTI system
(#568 by bnavigator)
* Cost and constraints are now allowed for
flatsys.point_to_point() (#569 by murrayrm)
