在啤酒工业发酵过程的温度计算机自动控制系统中,由于控制对象的纯滞后因子e~(-τ的存在,使得系统的稳定性受到破坏。本文在传统的PID控制基础上提出一种加进补偿网络的控制方法,从而解决了e~(-τ的影响问题。文中对PID控制算法作了精练的推导;对纯滞后因子e~(-τ降低系统的稳定性作了详细的分析;对加进的补偿网络的控制算法给出了理论上的推导和证明。
In the temperature computer automatic control system of fermentation process in beer industry, the stability of the system is destroyed due to the existence of the pure hysteresis factor e- (-τ) of the control object.This paper proposes a method of adding compensation based on the traditional PID control Network control method to solve the problem of e ~ (-τ effect. In this paper, the PID control algorithm was refined deduction; the pure lag factor e ~ (-τ to reduce the stability of the system made a detailed analysis; plus The control algorithm of advanced compensation network gives a theoretical derivation and proof.
