Abstract
In this paper, a super-twisting sliding mode controller with a time-varying sliding surface is proposed for electronic throttle control. The idea behind this control algorithm is to utilize a fuzzy logic controller to vary the sliding surface based on error variables, error and its first time derivative. The simulation results have confirmed the improved dynamic performance of the proposed control algorithm in terms of faster response compared with super-twisting sliding mode controller with a constant sliding surface. The improvement in the dynamic performance is achieved without compromising the stability, robustness and tracking accuracy.
