摘要/Abstract

摘要： 针对火电厂主汽温难以控制的特点,利用帝国竞争算法对主汽温串级控制策略进行了仿真优化研究。以带有限幅和限速执行器的主汽温串级PID控制系统为仿真对象,确定了合适的误差指标函数ITAE;对几种类型的串级PID控制方案进行了对比研究。仿真结果表明帝国竞争算法是一种便捷有效的参数优化方法,PID-PI型串级控制系统动态性能指标较均衡,抗干扰能力更强。

Abstract: Thermal power plants for the main steam temperature are difficult to control, using Imperialist Competitive Algorithm to accomplish main steam temperature cascade control strategy simulation optimization. The main steam cascade PID control system with limiting and speed actuator as simulation object determined the appropriate error indicator function ITAE criterion. Several types of Cascade PID control scheme were compared. Simulation results show that Imperialist Competitive Algorithm is convenient and effective method of parameter optimization, and PID-PI cascade type system has better balanced dynamic performance, anti-interference ability.
