积分时滞系统的内部反馈粒子群优化控制方法

摘要

The traditional PID controller has structural flaws in the integral process control, a kind of internal feedback particle swarm optimization PID control method is put forward, which solves the problem of controlling the integral process. The integral time-delay systems in superheated steam temperature system is difficult to be controlled , but by using the method brought in this paper, the simulation results of the steam flow temperature control system have non-overshoot, short adjusting time, which shows the rationality and validity of the PID control based on internal feedback PSO.%传统PID控制器在控制积分过程时存在结构上的缺陷,提出一种内部反馈的粒子群优化PID控制方法,解决了积分过程难以控制的问题.火力发电厂过热蒸汽温度系统是一种较难控制积分时滞系统,蒸汽流量温度控制系统仿真结果无超调、调节时间短,表明内部反馈的粒子群优化PID控制方法的有效性和合理性.
