Robust Control Design Using a Hybrid-Gain Finite-Time Sliding-Mode Controller
Amit Shivam, Kiran Kumari, Fernando A. C. C. Fontes
This paper proposes a hybrid-gain finite-time sliding-mode control (HG-FTSMC) strategy for a class of perturbed nonlinear systems. The controller combines a finite-time reaching la…
