比例積分微分(PID)控 制器發展已久,具有構造簡單及穩定控制之特性,因此被廣泛利用在各工業領域上。 而 PID控制器的控制參數對系統性能表現有很大的影響, 已有許多 文獻 提出各 種 簡單且被廣 泛應用的控制器參數調整法,但更有效的參數調整方法仍是研究上的一項重要議題。
本文應用水母演算法(Jellyfish Search, JS)於最佳比例積分微分控制參數搜尋,主要目的為使用水母演算法來搜尋降壓式轉換器之最佳化PID控制參數。本文於MATLAB上實現水母演算法並利用Simulink模擬降壓式轉換器電路,經過運算後會得到使目標函數最佳化之PID參數組合結果。本文比較使用水母演算法所得之最佳化參數與使用其他參數調整法所得的參數之控制器性能表現,根據模擬結果顯示,相較於I/O Data設計法、PID Tuner設計法與齊格勒調整法,本文所得之最佳化參數在電壓響應誤差量方面分別可改善96 %、31.23%與99.99 %。
With its characteristics of simple structure and stable control, the proportional integral derivative (PID) controller is extensively used in various industrial fields. Besides, the control parameters have a significant influence on the performance of PID controllers. Nowadays, although several simple and widely-used controller parameter adjustment methods have been proposed in the literature, an effective parameter adjustment method is still an essential issue in research.
In this study, Jellyfish Search (JS) algorithm is applied to search for the best proportional-integral-derivative control parameters; the primary purpose is to obtain the optimized PID control parameters of the buck converter by using the Jellyfish Search algorithm. This study implements the Jellyfish Search algorithm on MATLAB and uses Simulink to simulate the buck converter circuit. Using this approach, the PID parameter combination that optimizes the objective function will be obtained. This study compares the controller performance of the optimized parameter obtained by Jellyfish Search algorithm with those obtained by other parameter adjustment methods. According to the simulation results, compared with the I/O Data design method, PID Tuner design method, and ZN adjustment method, the optimized parameters obtained in this study can improve the accumulated square error of voltage response by 96%, 31.23% and 99.99%, respectively.
