Prescribed-Performance-Aware Hybrid-Gain-Based Robust Controller
Amit Shivam, Kiran Kumari, Fernando A. C. C. Fontes
This paper proposes a prescribed performance function aware hybrid gain finite time sliding mode control framework for a class of nonlinear systems subject to matched disturbances.…
Variable L0 Guidance Strategy: Enlarged Operational Envelope and Path-Following
Amit Shivam, Manuel C. R. M. Fernandes, Fernando A. C. C. Fontes +1
This paper presents a geometric and theoretical study of an exponentially varying look-ahead parameter for UAV path-following guidance. Conventional guidance laws with a fixed look…
Bifurcation-Based Guidance Law for Powered Descent Landing
Neon Srinivasu, Amit Shivam, Nobin Paul
This paper develops a new guidance law for powered descent landing of a rocket-powered vehicle. The proposed law derives the acceleration command for a point mass model of the vehi…
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…
