输出反馈变结构控制系统的设计

Design of Output Feedback Variable Structure Systems

提出了一种输出反馈的变结构控制方法。使用该方法可以不通过状态反馈或状态观测器，而只用系统的输出信号来设计变结构控制系统。本文讨论了该方法适用的系统类型、输出滑模平面的设计、控制策略的选择及系统的稳定区间等问题，并给出了相应的定理。计算机仿真结果证明了该方法的正确性。

This paper proposes a method to design output feedback variable structure control systems The method needs only output signals of systems,but doesn′t need state feedback or state estimators This paqer dicusses the type of the systems to be designed using the method,the design of output sliding mode,the determination of the control strategy and the stable region of the system The simulation results prove the validity of the method
