MR and LTV Synthesis Tools

Description

    a.  H-infinity synthesis of multi-rate sampled data LTI systems using LMI synthesis methods*

    b.  H-infinity synthesis of discrete-time LTV systems using LMI synthesis methods*

    c.  System type conversion (i.e. multi-rate LTI to discrete-time LTV)

    d.  LTV system balance, reduction, and truncation

    e.  LTV stability and stabilizability through eigenvalue and LMI solution methods*

    f.   Discrete system data structure conversion
 

 

* Mathworks LMI Toolbox not required.  One of two LMI solvers can be used: Mathworks LMI Toolbox (purchased separately)

or  xLMI (free, available below).  Only one of the LMI solvers must be installed to use this software
