| 英文摘要 |
| This paper focuses on the problem of gain-scheduled H1/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 H1/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. |
