Fixed-time input-to-state stability and applications to fixed-time sliding mode control

International Journal of Control
This paper investigates the robust stability properties of two simple fixed-time stabilizing controls tailored for scalar systems. These algorithms require a small amount of tuning parameter providing fixed-time stability, and ensuring trajectory robustness against disturbances and/or measurement noise.

Equivalence of Finite- and Fixed-time Stability to Asymptotic Stability

CoRR
In this paper, we present new results on finite- and fixed-time convergence for dynamical systems using LaSalle-like invariance principles. In particular, we provide first and second-order non-smooth Lyapunov-like results for finite- and fixed-time convergence, thereby relaxing the requirement of existence a differentiable, positive definite Lyapunov ...

Synchronization of Time-Varying Delayed Neural Networks by Fixed-Time Control

IEEE Access, 2018
This paper discusses synchronization of time-varying delayed neural networks by fixed-time control. First, several new fixed-time stability theorems of the dynamic system are discussed, and the estimation of the convergence time is also gained.
