摘　　要：由于循环水泵的大惯性、非线性以及时变性等特点,传统PID算法难以改善换热站循环水泵的控制品质。为实现循环水泵的精确控制,提出了一种基于变论域的预估模糊PID(Smith-Fuzzy-PID)控制器对循环水泵进行变频调速控制,满足集中供热系统末端用户的采暖需求。仿真结果表明,所提出的变论域Smith-Fuzzy-PID控制超调量为15.7%、上升时间为1.167 s、调节时间为8.306 s,3个性能指标均优于传统PID控制和模糊PID控制的相应指标,并且变论域Smith-Fuzzy-PID在模型无扰动和有扰动的情况下,都具有调节速度快、鲁棒性和抗干扰能力强等特点。Due to the large inertia,nonlinearity and time-varying characteristics of the circulating water pump,it is difficult for the traditional PID algorithm to improve the control quality of the circulating water pump of the heat exchange station.In order to realize the precise control of the circulating water pump,a predictive fuzzy PID(Smith-Fuzzy-PID)controller based on variable theory domain was proposed to control the frequency conversion speed regulation of the circulating water pump to meet the heating needs of the end users of the central heating system.The simulation results show that the overshoot of the proposed variable domain Smith-Fuzzy-PID control is 15.7%,the rise time is 1.167 s,and the adjustment time is 8.306 s,and the three performance indicators are superior to the corresponding indicators of traditional PID control and fuzzy PID control,and the variable domain Smith-Fuzzy-PID has the characteristics of fast adjustment speed,strong robustness and strong anti-interference ability in the cases of non disturbance and disturbance in the model.
