【Abstract】 Identification and control is presented for T-S fuzzy model of nonlinear system based on support vector machine (SVM) and genetic algorithm (GA). Structure of T - S fuzzy model can be determined by SVM with good generalization performance automatically, and system parameters can be optimized and estimated by GA. There are two parts for T -S model controller, including feedback control for subsystem with the maximum weight and global supervised control designed on sliding mode control which guarantees the system stability. The simulation results of identification and control illustrate the effectiveness of the proposed method.更多还原
