摘要
This paper studies the problem of set invariance analysis and gain-scheduled control for linear parameter-varying systems with actuator saturation. Based on a descriptor model transformation of the system, a less conservative condition is derived by relaxing the stability conditions presented in a previous paper. A linear matrix inequality-based optimization procedure is proposed to obtain the optimal time-invariant state feedback controller. In order to further improve the closed-loop performance, a gain-scheduled controller is constructed by collecting the interactions among the subsystems in a single matrix. Two examples are provided to illustrate the effectiveness of the results.
