摘　　要：为提高PVC胶槽温度控制的可靠性和精度,将模糊算法与PID算法结合并应用于PVC胶槽温度控制系统中,通过两种控制算法的优势互补,利用模糊控制算法求得PID参数修正系数,实现PID控制器3个参数的在线自调整。仿真结果表明:PVC胶槽温度模糊PID控制器的控制性能明显地优于常规PID控制器,温度控制精度达到±1℃,满足了PVC胶槽温度参数动态变化实时调节控制的需要,具有较好的自适应调节和鲁棒性。In order to improve temperature control performance,the fuzzy-PID algorithm was applied to the PVC plastic trough temperature control system.Making use of individual advantages of two control algorithms and the fuzzy control algorithm,the correction factors of PID parameter were obtained and online self-regulation of PID controller＇ s 3 parameters was realized.The simulation results show that the fuzzy-PID control system for PVC plastic trough temperature outperforms the general PID controller because of a±1℃control accuracy, outstanding adaptability and robustness,this can satisfy the requirements of real time controlling of PVC plastic trough temperature parameters dynamically.
