摘　　要：为提升轮胎直压硫化金属内模具电磁感应加热的温度控制精度,提高轮胎硫化质量,以多点位电磁线圈-鼓瓦模型为研究对象进行建模和有限元分析,确定了鼓瓦温度与电磁线圈的交流电电流强度之间的数学模型;在此基础上,建立了电磁线圈-鼓瓦模型的温度比例-积分-微分(PID)控制系统,并引入模糊算法进行优化。仿真结果表明,与PID控制相比,模糊PID控制温度曲线的上升时间缩短68.39%,调节时间缩短32.27%,超调量从0.097减小至0.009,减小90.72%,即引入模糊控制策略优化PID控制缩短了温度控制系统的响应时间和调节时间,减小了超调量,降低了鼓瓦温差,有效提高了鼓瓦加热时的温度控制精度。本研究可为轮胎直压硫化金属内模具电磁感应加热的温度控制技术提供有价值的参考。To improve the temperature control precision of the direct vulcanization metal internal mold of the tire during the electromagnetic induction heating and the quality of tire vulcanization,the multi-point electromagnetic coil-drum tile model was used as the research object for modeling and finite element analysis,and the mathematical model between the drum tile temperature and the AC current indensity of the electromagnetic coil was determined.Based on this model,the proportional-integral-derivative(PID)control system of the temperature of the electromagnetic coil-drum tile model was established,and the fuzzy algorithm was introduced for optimization.The simulation results showed that compared with PID control,the rise time of the temperature curve of the fuzzy PID control was shortened by 68.39%,the adjustment time was shortened by 32.27%,and the overshoot was reduced from 0.097 to 0.009,which was reduced by 90.72%.Therefore,the introduction of the fuzzy control strategy to optimize the PID control shortened the response time and adjustment time of the temperature control system,decreased the overshoot,reduced the heating temperature difference of the drum tile,and effectively improved the temperature control accuracy during the drum tile heating.This research could provide valuable references for the temperature control technology of electromagnetic induction heating for the direct-pressure vulcanization metal internal mold of the tire.
