摘　　要：传统的滑模控制方法在整个响应过程中,其不敏感性不能总被保持。为了克服这个不足,F.Harashima 等人提出了四段切换曲线组合成滑模线的控制方法。本文提出了该方法的不合理性,并给出了新的四段切换曲线,从而使系统在整个响应过程中均具有不敏感性,且使系统是时间次优控制。仿真结果表明,系统在参数变化及扰动情况下,仍能保持很好的跟随性能,优于传统的设计方法。The coventional sliding mode control cann't keep a system insensitive during entire response.To avoid this shortcoming,F.Harashima and others put forward a new strategy“Four Sliding line”.This paper points out the irrationalities of that strategy and presents an improved one.The improved strategy ensures the insensitivity throughout entire repo- nse and time suboptimal control.Simulation results verify that the improred strategy can guarantee a system in good traceability and keep the system insensitive to parametric variations and disturbances,which demonstrates the improved sliding curve have an advantage over the conventional sliding mode strategy.
