Temperature control system for booster production line based on fuzzy PID control

为了提高起爆具生产线中浇注锅温度的控制精度,以提高起爆具产品的质量,分析了起爆具生产线中浇注锅温度控制系统的组成,将模糊控制和常规PID控制结合起来,设计出了模糊PID控制器,通过以往对浇注锅温度控制的经验,制定出了PID 3个参数的模糊控制规则表,最后将模糊PID控制算法通过可编程逻辑控制器(PLC)编程来实现;在Matlab中的Simulink工具箱里搭建了模糊PID控制器和常规PID控制器模型,并对这两个控制器进行了仿真比较。研究结果表明,相对于常规PID控制器,模糊PID控制器具有更好的调节精度。该系统在生产线中的实际运用结果显示,模糊PID温度控制器效果较好,达到了预期的温度控制要求;系统适用于起爆具生产线中浇注锅的温度控制,对提高起爆具产品质量和生产效率具有一定的意义。

In order to improve the control accuracy of pouring pot temperature in booster production line and the quality of booster product,the components of pouring pot temperature control system in booster production line were analyzed.The fuzzy control and conventional PID control were combined together,then a fuzzy PID controller was designed.Through the past experience of pouring pot temperature control,the fuzzy control rule table of the three parameters of PID was formulated.Finally the fuzzy control algorithm was realized by the programming of programmable logic controller.Moreover,simulation comparison between the fuzzy PID controller and conventional PID controller was made in Simulink toolbox in Matlab.The results indicate that compared with conventional PID controller,the fuzzy PID controller has better regulation precision.Applied to the actual production line,the results indicate that fuzzy PID control is better,achieve the desired temperature control requirements,which is applicable to temperature control of pouring pot in booster production line and has great significance for improving the quality of primer product and production efficiency.
