摘要
本文研究变结构控制系统的鲁棒性,证明了在系统存在控制延迟、非线性以及对象参数和外扰的界限未知的情况下,变结构控制系统是鲁棒的,并提出了进一步增强这类系统鲁棒性的措施.数字仿真支持了理论结果.
In this paper, the robustness of variable structure system (VSS) is studied. It is shown that VSS is robust, when the control is delayed, the model of plant is nonlinear, the bound of plant parameters and disturbance are unknown. In order to strengthen the robustness, a design method for VSS is presented. The theoretical results are supported by digital simulation.
