【摘要】：研究了一类带有时变时滞的不确定非线性关联大系统的自适应模糊容错控制问题.用有界的参考信号代换模糊逼近器输入中的未知时滞信号,使得控制器的设计与应用不再依赖于时滞假设条件,使得控制器的设计和控制方法的应用更为方便.容错反推控制技术和自适应技术相结合来处理代换误差和逼近误差.所提出的方案能有效补偿所有4种类型的执行器故障,同时还可保证闭环系统的全局稳定性.仿真结果进一步验证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.
