摘　　要：针对传统的PID控制存在非线性、时滞性和大惯性的问题,提出了将传统PID控制器与控制模型相结合,在模糊自整定控制系统中串联一套即时的流量PID控制器。设计了一套基于STM32F407微控制器的智能的、有实时性的药型螺压挤出成型工艺温度控制系统,从温度和流量两方面实现温度调控,提高了系统的抗干扰能力,缩短了调温时间。利用Matlab对药型成型工艺温度控制系统的PID控制和串级模糊自整定PID控制进行仿真比较,证实串级模糊自整定PID控制器的调整精度、响应速度等各方面优于传统的PID控制器,具有广泛的应用前景。Aiming at the problems of nonlinearity,time-delay and large inertia of traditional PID control,a traditional PID controller was combined with the control model to set up an instantaneous flow PID controller in the fuzzy self-tuning control system.An intelligent,real-time temperature control system for screw-type extrusion molding process based on STM32F407 microcontroller was designed.Temperature control was realized from both temperature and flow,which improves the anti-interference ability of the system and shortens the temperature adjustment time.We used Matlab to simulate the PID control of the temperature control system of the propellant molding process and the cascade fuzzy self-tuning PID control,and the adjustment precision of the cascade fuzzy self-tuning PID controller was confirmed.The response speed is better than the traditional PID controller,which has broad application prospects.
