Continuous finite‐time TSM control for electronic throttle system

This article examines the position tracking difficulties of the electronic throttle (ET) system and presents a continuous finite‐time terminal sliding mode (TSM) control method. The development of this control method involves two procedures: (i) designing a global finite‐time observer to estimate the derivative and higher order derivatives of the ET system output, and the total disturbances; and (ii) construction of a continuous finite‐time TSM controller based on observer estimations, to ensure the realisation of fast finite‐time convergence of system output with a comparatively smooth control action. Comprehensive stability proof, simulation study, and experimental implementation are provided to affirm the applicability of the proposed method.
