Robust discrete gain-scheduled controller design: LMI approach

Paper in proceeding, 2014

This paper deals with robust discrete gain-scheduled controller design for uncertain LPV systems which ensures closed-loop stability and guaranteed cost for all scheduled parameter changes. The novel procedure is based on LPV paradigm, Lyapunov theory of stability and guaranteed cost from LQ theory. The feasible design procedures are obtained in the form of BMI and LMI. The class of control structure includes centralized or decentralized fixed order output feedbacks like PID(PSD) controller. Numerical examples illustrate the eectiveness of the proposed approaches.
