摘要：

This paper focuses on the problem of gain-scheduled H∞/H2 output feedback controller synthesis for continuous-time linear parameter varying (LPV) systems with parameter uncertainty and external disturbance simultaneously. First, the mathematical formulation and control objectives, including the H∞/H2 performance and regional pole placement, of gain-scheduled mixed-objective robust dynamic output feedback controller for continuous-time LPV systems are presented. Second, in order to further reduce the conservatism of this algorithm, several slack variables and parameter-dependent Lyapunov functions are employed to the well-established performance conditions. Then the desired gain-scheduled mixed-objective robust dynamic output feedback controllers are reformulated as efficiently tractable finitedimensional convex optimization problem in terms of linear matrix inequalities (LMIs). Finally, numerical examples of a quarter car model with an active suspension are given to illustrate the effectiveness of the proposed methods. © 2016, Editorial Department of Control Theory & Applications South China University of Technology.
