------------------------------------------------------------------- Fri Jan 5 16:14:20 UTC 2024 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Update to version 3.6.1: * use current version of the SLICOT-Reference routines v5.8 from Github * fixed phase in bode plot for system with poles/zeros at the origin * fixed duration of time responses like step for systems with oscillations ans improved graphical output ------------------------------------------------------------------- Wed Jan 3 09:49:57 UTC 2024 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Update to version 3.6.1: + Bugfix: numeric constants are converted into proper lti systems before being interconnected to discrete time-systems - Update to version 3.6.0: + zgrid: new function for grid lines with constant eigenfrequency and damping for discrete-time pole/zero maps + pzamp: added unit circle (for discrete-time) systems and axes to the pole/zero maps + allow discrete-time purely static gain systems with a sampling time + added metainfo file octave-control.metainfo.xml - Update to version 3.5.2: + fix build errors when installing in Octave 6 - Update to version 3.5.1: + fix build errors when installing in Octave 9 + more robust tests for some model reduction and identification functions ------------------------------------------------------------------- Wed Feb 16 00:52:20 UTC 2022 - Atri Bhattacharya <badshah400@gmail.com> - Update to version 3.4.0: * Fix lyapunov equ. in dlyap if B is non-symmetric (bug #49801). * Declare tf([1],[1]) as static gain. * Returned num and den of tfdate have same length (bug #43947). * Fixes for Octave 7.1.0: removed deprecated .+ operator and unsupported plot style. ------------------------------------------------------------------- Wed Sep 15 11:02:10 UTC 2021 - Atri Bhattacharya <badshah400@gmail.com> - Update to version 3.3.1: * Fixed time response for first order systems. - Changes from version 3.3.0: * New function rlocusx providing gain, damping and frequency for selected poles together with the possibility to generate open loop bode plots and simulations of the closed loop for selected closed loop poles. * Fixed several issues in bode, c2d, lsim and step. * Fixed issues in legends of time and frequency responses when * requested for multiple systems. * Fixed usage of deprecated LAPACK routines. * Added discretization method 'foh' to c2d. * Added tests for c2d with 'foh' and to dlyapchol. * Fixed transposing a tfploy. - Drop control-gcc-errors.patch: No longer required as fixed upstream. ------------------------------------------------------------------- Tue Nov 26 23:52:29 UTC 2019 - Stefan Brüns <stefan.bruens@rwth-aachen.de> - Update to version 3.2.0 * new function sgrid * New function: ss2ss * Fixed many warnings * added demos to rlocus, pzmap, bode, nichols, nyquist, impulse, lsim, ramp and step * improved pzmap to plot with only zeros - Update to version 3.1.0 * New function: damp * Changed nelem to numel and length to numel to remove the warnings during installation. * The Impulse section has been rewritten, and a new file - imp_invar.m - added. The old system tried to use the "zoh" to get an impulse response but that is impossible. * The new function "imp_invar.m" converts a Laplace tranfer function to a discrete tranfer function. * New functions: acker, dsort, esort. * Function lsim now plots inputs as well. * Class 'ss' should now work with complex inputs. * Extend nyquist plots. * Fixed warnings with newer Octave versions. ------------------------------------------------------------------- Sat Oct 31 19:56:24 UTC 2015 - dmitry_r@opensuse.org - Update to version 3.0.0 * Substantial parts of the most vital internals have been rewritten and streamlined in order to improve compatibility and reliability. * LTI models: Improved handling of key-value pairs in all constructors for LTI models. Support inheritance of LTI properties in many variations. Accept [] as an alias for unspecified sampling time (Ts = -1). Automatic vector expansion for input and output names. * dss Fixed a long-standing but undiscovered bug where 'dss (sys)' overwrites sys.e with an identity matrix even if sys.e was not empty. * ss Support for the special cases has been added. * tf, zpk, filt Restrict transfer function variable to the candidates 's', 'p' for continuous-time and 'z', 'q', 'z^-1', 'q^-1' for discrete-time models. * bode, bodemag, nichols, nyquist, sigma It is now possible to specify a frequency vector of length 1. * step, impulse, initial, ramp The time response functions now raise an error or warning if invalid arguments are passed to them. As it was the case for frequency response functions, they used to simply ignore invalid arguments. * lsim Support logical arrays as input signal. Before, logical arrays were simply ignored without notice, which could lead to unexpected results. Additionally, lsim received the same improvements as the other time and frequency response functions regarding invalid arguments. * pzmap Improved argument checks. * augstate New function for state-space models. Adds the state vector to the output vector. * connect The function no longer raises an error for name-based interconnections if some systems have common input names and one of these inputs are to be kept. * estim Add input/output/state names to the returned system. Support name-based selection of inputs (arguments 'sensors' and 'known'). ** sumblk Add signal names as input/output groups if argument n > 1. ** minreal If state-space models already have a minimal realization, then no state transformations are applied to the returned model. ------------------------------------------------------------------- Sat Oct 3 08:30:44 UTC 2015 - dmitry_r@opensuse.org - Update to versiob 2.8.5 * Bug fixes * Matlab compatibility improvements ------------------------------------------------------------------- Wed Sep 9 18:16:09 UTC 2015 - dmitry_r@opensuse.org - Update to version 2.8.4 * Bug fixes and minor changes ------------------------------------------------------------------- Tue Jul 7 17:34:40 UTC 2015 - dmitry_r@opensuse.org - Update to version 2.8.3 * Bug fixes and minor changes ------------------------------------------------------------------- Sat Jun 20 10:48:06 UTC 2015 - dmitry_r@opensuse.org - Update to version 2.8.2 * Bugfix release ------------------------------------------------------------------- Mon May 4 06:58:02 UTC 2015 - dmitry_r@opensuse.org - Update to version 2.8.1 * tf - Revamped the modifications of TB01ZD from control version 2.8.0. The function now uses LAPACK routines to find the maximum norm element. - Improved error handling when converting state-space models. ------------------------------------------------------------------- Tue Apr 7 21:24:46 UTC 2015 - dmitry_r@opensuse.org - Update to version 2.8.0 * zero Compatibility fix in the C++ oct-file to support the upcoming Octave 4.0. * isminimumphase Reverted changes from control-2.6.6. According to the definition of Byrnes/Isidori, the function tests whether the system has asymptotically stable zero dynamics. The poles are not tested. * series Fixed a bug which gave unnecessary error messages when the function is called with 4 arguments. * tf Resolved issues in MIMO state-space to transfer function conversion by implementing a more robust algorithm in SLICOT routine TB01ZD. * Support for 64bit indexing option. ------------------------------------------------------------------- Thu Feb 26 16:06:43 UTC 2015 - dmitry_r@opensuse.org - Split from octave-forge package, version 2.6.6 - Fix GCC errors: no return in non-void function * control-gcc-errors.patch
