Design of model reference adaptive law for a class of switching systems with controller failure

研究了一类带有执行器失效的切换系统的模型参考自适应控制的自适应律的设计方法。对于给定的系统控制器,利用构造Lyapunov函数,推导证明并得出切换系统在切换策略即执行器正常工作与执行器失效相互切换的情况下,设计切换系统的自适应律,保证切换系统的全局实用稳定。仿真结果表明,状态跟踪误差的收敛验证了此方法的有效性。

This paper studies the design method of adaptive reference law for model reference adaptive control of a class of switching systems with actuator failure. For a given system controller, use the construct Lyapunov function to derive the proof and derive the switching system in the switching strategy that is the actuator In the case of normal operation and actuator failure switching, the adaptive law of the switching system is designed to ensure the overall practical stability of the switching system. Simulation results show that the convergence of state tracking error verifies the effectiveness of this method.
