摘要： 针对具有随机时延和数据包丢失的网络控制系统的稳定性问题,考虑到系统存在不确定性及外部输入干扰,将控制输入施加饱和非线性约束,建立具有一般性的系统模型.基于Lyapunov方法,给出具有饱和非线性约束的网络控制系统的鲁棒稳定的充分条件.在此基础上,获得使系统具有γ次优、最优鲁棒H∞控制的充分条件,得到最优H∞镇定输出反馈控制律.仿真表明:H∞镇定判据是可行的,有饱和约束的鲁棒H∞优化控制方法是有效的.

Abstract: Aiming at the networked control systems with possibly stochastic network-induced delay and data packet dropout, the stability of networked control systems is studied. Taking account of the uncertainties of the systems and external disturbance input, the saturated non-linear restriction is imposed on control input to develop a generalized model for the systems. By Lyapunov method, the sufficient conditions are given for the robust stability of networked control systems with saturated non-linear restriction. Then, the sufficient conditions are given for γ suboptimum and optimum robust H∞ control, thus obtaining the lainfw of optimal H∞ output feedback control. Simulation results showed that the stability criteria are feasible and the robust H∞ optimal control method with saturated non-linear restriction is valid.
