The present article provides a sufficient condition to ensure output finite-time and fixed-time stability. Comparing with analogous researches the proposed result is less restrictive obtained for wider class of systems. presented stability used adaptive control design, where state vector plant extended by adjustable parameters.

The adaptive fixed-time control problem for nonlinear systems with time-varying actuator faults is investigated in this paper. A novel controller designed via combining the Lyapunov stability theory backstepping method. It can be adapted to both system uncertainties and unknown faults. Compared existing fault-tolerant schemes subject faults, neural networks scheme make sure that tracking error ...
