control-4.1.0

Most important changes:

• lqg, lqgtrack, lqgreg, reg: new functions for linear dynamic output feedback design including estimator and state feedback
• lqry, lqi: new linear quadratic regulator design function, output weighting and with integral part
• c2d: impulse invariant discrete-time models for MIMO systems and state space representations
• New algorithm for imp_invar, also allowing MIMO systems
• tfdata: returning coefficient lists of same length for numerator and denominator (bug #43947)
• allow time responses (like, e.g. stepor impulse) for several systems with different sizes

Please note: The source archives Source code (zip) and Source code (tar.gz) are automatically added to the release's assets by Github and do not contain the complete sources since this project uses submodules for the SLICOT library. All sources that are required for installing the control package in GNU Octave are included in the downloadable archive file control-x.y.z.tar.gz. The complete sources (including, e.g., the ones for packaging) are available in the repository which has to be cloned using the option --recurse-submodules.

control-4.0.1

Most important changes:

• warning messages do not include trace information anymore
• mktito: changed name of inputs and outputs for compatibility (bug #63736)
• more robust test using Markov parameters for several model reduction routines (bug #65218)
• fix graphic styles in pzmap (bug #57716)

control-4.0.0

Most important changes:

• 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 (credits to Juan, see bug #61355, comment #10
• Fixed duration of time responses like step for systems with oscillations and improved graphical output

• added metainfo file octave-control.metainfo.xml

control 3.5.2

• fix build errors when installing in Octave 6

control 3.5.1

• fix build errors when installing in Octave 9
• more robust tests for some model reduction and identification functions
