摘　　要：文中给出了加热炉系统的Fuzzy-PID控制器设计方案,Simulink仿真和实验结果表明:它综合了模糊控制的动态性能和PID控制的稳态性能,当被控对象参数时变和非线性因素较大时,控制效果优于PID控制,提高了工业现场加热炉系统的适应能力和鲁棒性。仿真寻优Fuzzy-PID满刻度时的系统响应并确定稳态精度。This article revealed the combined control strategy of Fuzzy-PID in heating furnace. The simulation and testing results indicated that Fuzzy-PID Composite Controller combined dynamic of Fuzzy control and stability of PID control, when the charged object parameter time-varying and nonlinear factors is larger, it is better than PID control and can promote adaptability and robustness of heating furnace systems in industrial sites. The essay also provided us with the best tuning parameters and stabilized precision at the given temperature.
