Fuzzy Integral Sliding-Mode Parallel Tracking Control Approach for A Class of Nonlinear Systems

The paper presents a fuzzy integral sliding-mode parallel tracking control method for general nonlinear systems based on the Takagi-Sugeno (T-S) fuzzy. By introducing an integral equation of the output tracking error, a corresponding fuzzy tracking model is established. Then, a fuzzy integral sliding-mode parallel tracking control strategy is designed to drive the original nonlinear system to track the expected reference signals in the H∞ sense. The proposed methodology enjoys a favorable feature that some assumptions on the system matrix required in the published approaches are eliminated. Finally, the feasibility and advantages of the developed tracking control strategy are demonstrated by a numerical example.
