| 摘 要： | 针对具有模型不确定和时变干扰的线性离散时滞网络控制系统,提出了一种新的滑模控制器的设计方法.证明系统在该控制器的控制下,全局一致有界收敛,并给出了收敛的界.该方法降低了常规滑模控制中的抖振并增强了系统的鲁棒性.由于不需要如常规离散滑模控制那样判断扰动和不确定的界,使该设计方法简单易行,并降低了系统抖振现象.最后将其应用在导弹姿态控制系统的设计中,取得了良好的效果.

| Abstract: | A discrete-time sliding mode controller for linear time-varying systems with time-delay is proposed.The proposed method guarantees that the system state is globally uniform ultimately bounded in the presence of time-varying disturbance and uncertainty and network induced time-delay.The control law is applied to design of missile attitude control system.Simulation result show the controller can reduce system chattering and have strong robustness. |
