چکیده

An algorithm for a robust, fuzzy-logic based, sliding mode control is proposed for a class of discrete systems. The algorithm is based on input/output measurements and is suitable for real-time control. It combines soft-computing methods with advanced sliding mode control. The controller design is carried out via Lyapunov’s direct method. The new controller is compared to the optimally tuned PID controller and shows an increased robustness with regard to the variation of the main process parameters and much better set point tracking characteristics. The new controller also exhibits very good disturbance rejection properties comparable or better than that obtained by the optimally tuned PID controller.

Eliminating chattering phenomenon in sliding mode control of robot manipulators in the joint space using fuzzy logic

In industrial robotic manipulator, due to the presence of quite nonlinear dynamic and structural and nonstructural uncertainties, a precise model is not easily obtained. As a result, designing a controller with a suitable function based on system model is a challenging issue. Sliding mode control is a robust control with numerous applications which can overcome the aforementioned uncertainties....

Design of robust fuzzy Sliding-Mode control for a class of the Takagi-Sugeno uncertain fuzzy systems using scalar Sign function

This article presents a fuzzy sliding-mode control scheme for a class of Takagi-Sugeno (T-S) fuzzy which are subject to norm-bounded uncertainties in each subsystem. The proposed stabilization method can be adopted to explore T-S uncertain fuzzy systems (TSUFS) with various local control inputs. Firstly, a new design is proposed to transform TSUFS into sliding-mode dynamic systems.In addi...
