A New Nonlinear Optimal Control Design Approach for a Chemical Reactor

本文针对具有非线性动态特性的连续搅拌釜式反应器（ＣＳＴＲ），提出了一种基于分步变换的控制器设计方法．通过引入一种简单的中间非线性模型和相应的非线性状态变换，综合得到了一种新的非线性系统的非线性控制器设计方法．最后的控制仿真结果表明这种设计方法是十分有效的．

For a continuously stirred tank reactor (CSTR) with nonlinear dynamic characteristic,the paper addresses a controller design approach based on a novel step-by-step transformation. An intermediate nonlinear model and corresponding nonlinear state transformation are proposed and proved to be effective in nonlinear controller design. Then a new nonlinear controller design approach is obtained. The simulation study of a CSTR shows that this approach is quite effective.
