摘要
The paper mainly studies the procedure for the linearization and control of Affine Nonlinear Parameter Varying (ANPV) system. The Takagi-Sugeno(T-S) fuzzy modeling approach is adopted to deal with the nonlinearity. As a result, the Linear Parameter Varying(LPV) T-S fuzzy system with required accuracy can be obtained. Then, through bringing in the parameter-dependent Piecewise Quadratic Lyapunov Functions (PQLFs), the H-infinity stability problem and the output-feedback H-infinity control problem of the LPV T-S fuzzy system are explored. respectively. The sufficient conditions are both given in Linear Matrix Inequalities (LMIs) form. At last, the numerical example is executed for validation and the simulation results show the effectiveness of the above approaches.
