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.
