【摘要】:研究了一類帶有時變時滯的不確定非線性關聯(lián)大系統(tǒng)的自適應模糊容錯控制問題.用有界的參考信號代換模糊逼近器輸入中的未知時滯信號,使得控制器的設計與應用不再依賴于時滯假設條件,使得控制器的設計和控制方法的應用更為方便.容錯反推控制技術和自適應技術相結合來處理代換誤差和逼近誤差.所提出的方案能有效補償所有4種類型的執(zhí)行器故障,同時還可保證閉環(huán)系統(tǒng)的全局穩(wěn)定性.仿真結果進一步驗證了本文方法的有效性.
[Abstract]:In this paper, the adaptive fuzzy fault-tolerant control problem for a class of uncertain nonlinear correlated large-scale systems with time-varying delays is studied. The bounded reference signal is used to replace the unknown time delay signal in the input of the fuzzy approximator, which makes the design and application of the controller no longer depend on the time delay assumption, and makes the design of the controller and the application of the control method more convenient. Fault-tolerant backstepping control technology and adaptive technology are combined to deal with substitution error and approximation error. The proposed scheme can effectively compensate all four types of actuator failures, and at the same time ensure the global stability of the closed-loop system. The simulation results further verify the effectiveness of the proposed method.
