  1. This thesis presents an effective way to design pid controller through a combination of adverse deduce and genetic algorithm. the relationship between pid parameter and the root of the characteristic equation of the closed loop control system has been found out directly

    本文直接找出pid參數與閉環控制系統的特徵方程的根之間的關系,只要使特徵方程的根在z平面的單位圓內任意取值,然後再求出相應的pid參數,則閉環控制系統必然是穩定的。
  2. As long as the root of the characteristic equation is within the unit circle of z - plane and the corresponding pid parameter is got, the closed loop control system is sure to be stable. although the root of the characteristic equation can vary within the unit circle of z - plane, different value may affect the control property differently. therefore, it is better to optimize the root, here the optimizing method is carried out by genetic algorithm

    本文所採用的這種確定pid參數的方法,雖然可以使特徵方程的根在z平面的單位圓內任意取值,但各種取值情況對變風量空調系統的控製品質的影響卻不同,因此,要對各種特徵方程的根的取值情況進行尋優,本文採用遺傳演算法對特徵方程的根進行尋優,從而使控制器的參數得以優化。
