Robust Fixed-Time Stability: Application to Sliding-Mode Control [PDF]
IEEE Transactions on Automatic Control, 2022 This article deals with robust fixed-time stability and stabilization. First, new global robust fixed-time stability results are proposed for scalar systems by using constant and variable exponent coefficients. Then, they are applied to global robust fixed-time stabilization of a class of uncertain nonlinear second order systems by using sliding mode ...
