Discrete Gain-Scheduled Controller Design: Guaranteed Cost and Affine Quadratic Stability Approach

Paper i proceeding, 2013

Our paper deals with discrete gain-scheduled controller design which ensures closed-loop stability and guaranteed cost for all scheduled parameter changes which lie in closed set Ω. The novel procedure is based on Lyapunov theory of stability, guaranteed cost from LQ theory and BMI. The class of control structure includes decentralized fixed order output feedbacks like PSD controller. Numerical examples illustrate the effectiveness of the proposed approach.
