Stable Model Predictive Control Based on TS Fuzzy Model With Application to Boiler-turbine Coordinated System
摘要
Abstract
A stable model predictive control based on fuzzy Lyapunov function and TS fuzzy model was proposed. The main idea of the proposed approach is to design a parallel distributed compensate control law in such a way that a fuzzy Lyapunov function is constructed with minimizing the upper bound of the infinite or quasi-infinite objective function in the fuzzy model predictive control. Therefore, the predictive controller can guarantee both the stability of the closed-loop fuzzy model predictive control system and input constraints while obtaining the optimal transient performance. It is shown that the controller is obtained by solving a set of linear matrix inequalities. Fuzzy Lyapunov function reduces the conservatism of common Lyapunov function and piecewise Lyapunov function, it enlarges the feasible area of the predictive controller. The simulations on numerical example and nonlinear boiler-turbine coordinated system of unit power plant demonstrate the advantage and effectiveness of the proposed methodology.关键词
