摘要: 针对连续搅拌反应釜系统(CSTR)和生物反应等连续系统,采用梯度线性化,设计一种连续变增益控制器,主要思想是先利用梯度线性化方法得到非线性系统的一系列局部线性化模型,结合H理论和极点配置得到变增益矩阵,通过拟合得到连续变增益H控制器,再引入模糊隶属度函数,使控制器兼顾快速特性和良好的阻尼特性,保证系统始终具有较好的动态性能。仿真结果说明了此控制器设计方法的有效性。

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.
