Abstract: Referring to continuous systems such as CSTR and bioreactor,based on gradient linear method,a new approach to the design of a fuzzy continuous gain scheduled H controller,in which a series of linear models are got.Considering H theory and LMI approach,the variable gain matrixes are designed,then the controller is got by fitting.Fuzzy membership function is used to possesses the characteristics of a fast response and a well-damped response.So the system always has a good dynamic performance.The simulation shows the validity of this method.
