Robust Gain-Scheduled PID Controller Design with Guaranteed Cost

Other conference contribution, 2016

A novel unified approach to design of robust controller, gain-scheduled controller (GSC), and robust switched controller with arbitrarily switching algorithm is presented. The proposed design procedure is based on the Bellman-Lyapunov equation, guaranteed cost, and robust stability conditions using parameter-dependent quadratic stability approach. The obtained feasible design procedures for robust, GSC, and switched controller design are in the form of bilinear matrix inequalities with guaranteed convex stability conditions. The obtained design results and their properties are illustrated in simulation examples.
