This work addresses the fixed‐time fault tolerant control problem for nonstrict feedback switched nonlinear systems whose subsystems have chained integrators with positive odd rational powers. Besides, the powers of different channels and switched subsystems can be also possibly different. The fixed‐time fault tolerant control law is formulated after using the adding one power integrator method, homogeneous system theory, backstepping technique, nested saturation control approach, which is capable of guaranteeing the global fixed‐time stability for the resulting closed‐loop stability. A numerical simulation example is given to validate the feasibility and effectiveness of the developed control strategy.

一类切换非线性系统的定时容错控制

这项工作解决了非严格反馈切换非线性系统的固定时间容错控制问题，该系统的子系统已将具有正奇有理次幂的积分器链接在一起。此外，不同通道和交换子系统的功率也可能不同。固定时间容错控制律是在加入一种功率积分器方法，齐次系统理论，反推技术，嵌套饱和控制方法之后制定的，它能够保证全局固定时间的稳定性，从而达到闭环稳定性。数值算例验证了该控制策略的可行性和有效性。
