H-infinity control for continuous stirred tank reactor based on Takagi-Sugeno fuzzy bilinear models
基于Takagi-Sugeno模糊双线性模型的连续搅拌反应釜H∞控制

This paper is concerned with the H-infinity control for a class of continuous stirred tank reactor (CSTR) systems, in which the nonlinear dynamics are described by Takagi-Sugeno fuzzy bilinear models. By introducing two free matrix variables, we derive a new sufficient condition, in terms of linear matrix inequalities, of the global stability with a prescribed H-infinity performance level for the closed-loop fuzzy bilinear systems. The controller design method is also given. Simulation results of a CSTR system illustrate the effectiveness of the design method.
