一类连续非线性系统的动态输出反馈H∞控制器设计
Dynamic Output Feedback H_∞ Controller Design for a Class of Continuous-Time Nonlinear Systems
摘要
Abstract
The dynamic output feedback H∞ controller design for a class of nonlinear continuous-time systems with nonlinear uncertainties is concerned.The resulting design is such that the closed-loop system not only is asymptotically stable,but also meets the prescribed H∞ norm constraint.A new method which combines S-procedure approach to solve the nonlinear uncertainties is proposed.A sufficient condition for the existence of such a controller is obtained by using appropriate Lyapunov functional and linear matrix inequality(LMI) technique.In addition,based on this result,a convex LMI-based optimization method is developed to obtain the controller.Finally,a numerical example is provided to demonstrate the effectiveness of the proposed design.关键词
