一种自带修正因子的酸碱度复合控制系统

Application of Compound Control with Amendment Factors in the System of Acid Alkali Allocate

由于酸碱度调配过程的非线性和大滞后性以及系统的实时和精度要求,传统的控制方法无法得到高质量的控制效果。而模糊控制不依赖对象的数学模型,但对稳态误差却很难从根本上加以消除,考虑到PI控制对稳态误差有很好的清除作用,故系统采用了一种自带修正因子的Fuzzy-PI复合控制策略。

Because the acid alkali titration is nonlinear and stagnant and the system demands real time and precision,the traditional control doesnt obtain high quality effect.The fuzzy control doesnt rely on any model,but it cant clear the steady error thoroughly.Considering PI control,the system has adopted the fuzzyPI compound control with amendment factors.
