摘要 针对直流无刷电机的远程网络控制系统中的控制时滞和参数不确定的问题,采用线性非奇异变换将控制存在时滞的线性系统转化为无时滞系统;借助于二次型时间最优的方法,利用二阶超螺旋算法,设计出简单、易于实现的二阶滑模控制器。仿真结果表明,二阶滑模变结构控制器的有效性和正确性,算法对负载和参数的变化具有很强的鲁棒性。 The aim of this paper is dealing with the remote control system of brushless DC motor robust speed control with input time delay and parameters varieties.The linear system with input time-delay is transformed into the equivalent non-delayed system,and then a simple and easily speed controller is designed by introducing optical algorithm and super twisting algorithm.The simulation results show that the second order sliding mode controller is corrected and effective,and at the same time,this strategy has very strong robustness against load disturbances and parameters varieties the chattering is attenuated availably.
