摘要
针对裤袜包装制袋过程中热封切刀对恒温控制的需要,分析了热封切刀温度的影响因素,得出了简化模型。采用了以PIC16F877为核心的恒温控制系统,控制器采用模糊控制和PID复合的控制算法。通过控制可控硅的闭合时间,达到了温度控制的目的。MATLAB仿真表明,采用模糊控制和PID复合的控制方法能有效降低超调量,减少调节时间,该系统具有良好的动态特性。
According to the requirement of stable temperature control of heat sealing cutting knife in pantyhose packa- ging bag-making process, the influencing factors of heat sealing cutting knife temperature were analyzed and its simpli- fied model was established. The control system based on PIC16F877 was designed, and the algorithm of controller was fuzzy-PID. Temperature control was realized through control the closed time of SSR. The results of MATLAB simula- tion showed that fuzzy-PID controller can cut down the overshoot and reduce the setting time; this system has good dy- namic characteristic.
