摘　　要：针对热风回流焊机温度模糊-PID复合控制系统中的模糊控制器进行了较为详细的设计,并利用MATLAB对模糊控制、PID控制和模糊-PID复合控制3种控制系统进行了仿真实验。比较结果表明:热风回流焊机温度控制系统采用模糊-PID复合控制方式,不仅比单独的模糊控制方式具有更高的稳态性能,而且比单独的PID控制方式具有更好的动态性能。A more detailed design is made for fuzzy controller in hot air reflow machine temperature fuzzy - PID compound control system. And three kinds of control systems, which are MATLAB for fuzzy control, PID control and fuzzy - PID compound control, were simulated. Comparison results showed that： Hot air reflow temperature control system using fuzzy - PID compound control not only has a higher steady - state accuracy than a single fuzzy control, but also a faster dynamic response than a single PID control.
