摘要
微生物发酵过程的温度控制精度非常重要,发酵罐罐体温度是通过夹套中的水温来调节的,使用加热器和冷却水调节夹套温度进而控制发酵罐温度。由于温度对象是滞后积分对象,使用传统的PID控制,控制效果差,因此对传统PID控制进行了改造。研究了积分分离PID,指数积分PID和FuzzyPID控制算法在发酵过程温度控制中的应用。实践证明,经过改进的PID算法的控制效果明显提高。
Temperature control of biological fermentation is very important. Because of time-delay and integral characteristics of the plant, traditional PID control algorithm is not qualified. So it was developed. Application of integration separated PID control, exponential integration PID control, and fuzzy PID control of temperature of biological fermentation was studied. It was proved that control performance was greatly improved using developed PID control algorithm.
