摘要:In this talk, we discuss the controller synthesis for systems with both quantization error and fading disturbance. Since the two distortions have distinct features, we appeal a uniformed framework and quadratic mean square (QMS) stability to handle such problem. An observer-based output feedback controller is proposed and designed to achieve the QMS stability of the closed-loop system, and all QMS stabilizing controllers in this structure are characterized in terms of an inequality involving the Mahler measure of the plant, together with an algebraic Riccati inequality. Stabilizability conditions are related to worst signal-to-noise ratio induced from distortions. Based on this parameterization, additional system performance requirement is further addressed. Moreover, following the similar thread, a multi-objective control problem for systems with structured multiplicative input noises is tackled. The Nash game methodology is adopted, and a necessary and sufficient condition is analytically given in terms of two cross-coupled modified algebraic Riccati equations (MAREs). Based on the stabilizing solutions to MAREs, bounded causal equilibrium strategies are thus conducted and the resulting control law optimizes some specific performance together with a guaranteed worst case performance.
