一种智能快速比例积分控制器的设计

Design of the Intelligent Rapid Proportion Integral Controller

采用常规比例积分PI控制算法的系统难以实现快速响应性能,综合最大值控制、PI控制、分段控制及专家控制的优点,设计了一种智能快速PI控制器。仿真研究表明,这种控制器能在被控对象模型参数或外界环境发生变化时,运用专家知识自动调整控制器的算法和参数,使系统既可快速响应,又无太大超调,还具有较强的自校正性能。

It is difficult to meet the rapid performance for the normal PI controller. Combining the maximum control, PI control, piecewise control and expert control, a kind of intelligent rapid PI controller can be designed. This simulation results show, that this kind of controller can auto tune its algorithms and parameters by using expert＇s knowledge on changing of model parameter for controlled object or surround- ing environment, so that the system response is rapid, with limited overshoot, and satisfactory self-adjustable capacity.
