Observer-based output feedback gain-scheduled controller design

Paper i proceeding, 2015

Our paper deals with the observer-based output feedback gain-scheduled controller design 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. To access the performance quality a quadratic cost function is used. The obtained design procedures are in the form of BMI. The class of control structure includes decentralized fixed order observer-based output feedback like PID controller. Numerical examples illustrate the effectiveness of the proposed approach.
