研究了具有随机延时的网络伺服控制系统的镇定问题。为了改善系统的控制特性,提出延时相关增益调度状态反馈积分控制器。采用状态观测器来估计状态参数,应用增广矩阵法将闭环系统建模为闭环切换系统,以跟踪误差作为控制器输出。通过构造依赖往返延时的 Lyapunov函数推导了闭环系统随机稳定条件。仿真结果验证了该方法的有效性。
研究瞭具有隨機延時的網絡伺服控製繫統的鎮定問題。為瞭改善繫統的控製特性,提齣延時相關增益調度狀態反饋積分控製器。採用狀態觀測器來估計狀態參數,應用增廣矩陣法將閉環繫統建模為閉環切換繫統,以跟蹤誤差作為控製器輸齣。通過構造依賴往返延時的 Lyapunov函數推導瞭閉環繫統隨機穩定條件。倣真結果驗證瞭該方法的有效性。

The paper investigates the stabilization problem for a class of networked servo control systems with stochastic time -delays .To improve the control performance of the system ,the delay -dependent gain scheduling -based state feedback integral controller is proposed .Since not all the states are available in practice ,a local observer is utilized to estimate the state vector .With the augmenting technique ,we ob‐tain closed-loop switched systems .The tracking error is chosen as the controlled output .The stability conditions are derived by using the round -trip time delay -dependent Lyapunov approach .Simulation re‐sults are given to demonstrate the effectiveness of the proposed approach .
