摘要
针对一类具有执行器组合故障的多输入单输出非线性最小相位系统提出了自适应容错跟踪控制方案。考虑系统执行器卡死和部分失效组合故障,基于微分几何反馈线性化,设计了模型参考自适应容错控制算法。设计的控制律能够保证系统在执行器故障时闭环系统稳定,而且渐近跟踪给定的参考信号。仿真结果表明了所提方法的有效性。
An adaptive fault tolerant tracking control scheme is proposed for a class of multi-input single-output(MISO) minimum phase systems with multiple actuator failures.Based on differential geometry feedback linearization method,a model reference adaptive fault tolerant control scheme is designed for the system with actuators lock in space and loss of effectiveness failures.The proposed control law can guarantee that the closed-loop system with actuator failures is stable and asymptotically tracks the given reference signals.Simulation results demonstrate the effectiveness of the proposed method.
