滑模预测控制在纯时滞系统中的应用

Application of Sliding Mode Predictive Control in Pure Time Delay System

针对纯时滞系统跟踪问题,设计一种离散滑模预测控制器。通过引入预测模型来预估未来的输出,从而消除时滞带来的控制误差。用估计输出设计滑模面,计算出对应的滑模控制律,并针对某时滞系统进行跟踪控制仿真实验。结果表明:该控制器可以有效克服时滞,具有良好的跟踪和抗干扰能力。

For the tracking problem of pure time-delay systems,a discrete sliding mode predictive controller is designed.By introducing a prediction model to estimate the future output,the control error caused by time lag is eliminated.Design the sliding mode surface with the estimated output,calculate the corresponding sliding mode control law,and carry out the tracking control simulation experiment for a certain time-delay system.The results show that the controller can effectively overcome the time lag and has good tracking and anti-jamming capabilities.
