Type: article
Abstract: This work introduces a novel second-order sliding mode (SOSM) controller for the control of dynamicuncertain systems based on fuzzy logic. An efficient sliding surface design approach for improving controllerperformance is to use time-varying sliding surfaces. The proposed controller incorporates second-order slidingmode control, fuzzy logic control, and adaptive control benefits. The proposed controller ensures the system'sreaching conditions, stability, and robustness. The proposed controller is also well-suited for straightforwarddesign and implementation. In order to rotate the sliding surface in a way that improves the trackingperformance of the system under control, this control strategy uses a time-varying slope in the sliding surfacefunction and a straightforward two-input single-output fuzzy logic controller. The proposed controller isstudied with a ship steering model in comparison with a conventional second-order sliding mode controllerwith a fixed sliding surface. Simulations of the ship steering system using MATLAB/SIMULINK show thatthe proposed controller outperforms the typical second-order sliding mode controller.
