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。
A discrete-time sliding mode controller for linear time-varying systems with time-delay is pro- posed. 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.
