为了实现对铝包钢丝温度的在线控制，采用自适应模糊 PID方法研究感应加热过程中的温度控制问题。利用自适应模糊控制器在线调整PID控制器的3个参数，实现了模糊智能控制技术与PID常规控制的结合，控制器根据当前温度与设定温度值的差值和差值变化率来实时调整 PID 参数的变化量。利用MATLAB的Simulink工具箱对控制器进行了设计和仿真，仿真结果表明，这种自适应模糊PID控制器既具有模糊控制灵活、响应快、适应性强等优点，又具有P ID控制精度高的特点，改善了铝包钢感应加热系统温度的控制效果。

In order to realize the online control of the temperature of steel wire ,a self‐adaptive fuzzy‐PID control method was pro‐posed to research the issue of temperature control in the induction heating process .By using self‐adaptive fuzzy control technology adjusting the parameter of PID controller ,the combination of fuzzy intellectual control and PID control technology was realized , which could adjust PID parameters based on deviation and the deviation change .Simulink toolbox of MATLAB was used to design and emulate the controller .The simulation study shows that the controller possesses both the flexibility and adaptability of fuzzy con‐troller and the precise character of PID controller .It improves the control effect of aluminum‐clad steel wire induction heating sys‐tem .
