Major Bug Fixes
The Control System Toolbox 5.2 includes several bug fixes made since Version 5.1. This section describes important Version 5.2 bug fixes.
allmargin function converts ZPK models to TF format only when there is an algebraic loop in your system. This change ensures that the SISO Design Tool can correctly diagnose closed-loop stability (open loop is always in ZPK format).
The dlinmod function now correctly linearizes all multirate discrete or hybrid (continuous and discrete) Simulink models when using Jacobian-based linearization.
Formerly, bad edge cases in the orthogonalization loop caused a divide by zero in the
place function. This is no longer the case.
