【摘要】 研究了一类具有非线性输人的时滞系统的滑模控制问题,针对状态未知的非线性时滞不确定系统,采用变结构控制方法,使估计状态在控制律的作用下在有限时间到达滑动面,并最终到达原点,得到使闭环系统渐近稳定的充分条件.并用仿真例子说明了该方法的有效性和可行性.更多还原

【Abstract】 The output feedback sliding mode control for time-delay sys-tems is dealed with.The system states are unmeasured,and the external disturbance isn’t admissible,a sliding mode control scheme is proposed based on the state estimates.By utilizing a novel switching function,the derivative of the switching function is ensured to be finite variation.It is shown that the sliding mode in the estimation space can be attained in finite time,and the sufficient condition for the asymptotic stability of the overall closed-loop systems is derived.Finally,a simulation example is shown to illustrate the proposed method.更多还原
