Generalized Super-Twisting Observer for a Class of Interconnected Nonlinear Systems With Uncertainties

Year: 2025

Type: article

Abstract: The Generalized Super-Twisting Observer (GSTO) is extended for a strongly observable class of nonlinearly interconnected systems with bounded uncertainties/perturbations. A nonsmooth strong Lyapunov function is used to prove the finite-time convergence of the proposed observer to the true system’s trajectories, in the presence of the uncertainties. A case study on the interaction between two food production systems is presented, comparing the proposed observer with the High Gain observer. The results emphasize the critical role of the GSTO’s discontinuous term in achieving exact estimation.
