中文摘要 | 本文提出以模糊控制器修正傳統PID控制器之積分器控制量的方法,以改善其步階響應性能。首先採用以模糊關係式為基礎的辨別法,得到含PID控制器在內的控制系統的模糊模式,據此估計依前向差分法定義之誤差變化量;再根據誤差與誤差變化量相平面軌跡圈,制定模糊控制規則,對積分器控制量提供修正量。以此模糊控制器為輔控制器,用於改善以PID為主控制器之直流伺服馬達定位控制系統之性能。實驗結果顯示,本文所提修正積分器控制量的效果,優於前篇【1】所提修正PID控制器總輸出量的教果,不論在最大超越量或安定時間方面皆有顯著的的改善;且本控制器具有良好的強鍵性。 |
英文摘要 | Proposed is a fuzzy controller, which provides correction quantites to the integrator outputs to improve the step response performance of a PID controller. First, use the identification method based on fuzzy relational equation to get a fuzzy model of the control system including the host PID controIIer. This fuzzy model is used to estimate error change defined by forward difference method. Then, set up fuzzy rules based on the phase plane trajectory of error and error change to provide correction quantities to the control outputs of the integrator. The fuzzy controller thus designed is used as a servant controIIer to improve the performance of a position control system of a dc-servo motor with a host PID controller. Experimental results show that the proposed method, which provides correction quantites to the integrator outputs, is better than the previous one in [1], which provides correction quantites to the total control outputs of the host PID controller. Both of the maximum overshoot and the settling time are reduced significantly. Furthermore, the proposed controller is robust. |
