| 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。

| Abstract: | According to the requirement of stable temperature control of heat sealing cutting knife in pantyhose packaging bag-making process, the influencing factors of heat sealing cutting knife temperature were analyzed and its simplified 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 simulation showed that fuzzy-PID controller can cut down the overshoot and reduce the setting time; this system has good dynamic characteristic. |
