利用基因演算法於直流無刷馬達位置控制分析

ANALYSISOF POSITION CONTROLOF DC BRUSHLESS MOTOR USING GENETIC ALGORITHM

摘要


本文旨在以基因演算法搜尋最佳化PID控制器控制參數的增益值,應用於直流無刷旋轉馬達(BLDC)系統,以期達到位置控制之目的。基因演算法(GA)進行參數搜尋工作,其適應性的交配與突變率公式可避免落入區域值而加速收斂。實驗部分使用智控科技提供的直流無刷馬達搭配功率放大器、TI DSP (TMS 320LF2407)控制器加以驗證本文控制法則之可行性。結果顯示以GA設計的最佳參數值可快速的追隨到位置命令。

Investigated in this thesis is the application of a genetic algorithm (GA) for searching optimal parameters of a PID controller for a DC brushless rotary motor position control system. The gains of the PID controller are searched simultaneously through adaptive genetic algorithm (GA) whose adaptively crossover and mutation rate can avoid falling into local optimum and speed up the convergence. As for the experiment part, we use the DC brushless rotary motor, power amplifier and TI DSP (TMS 320LF2407) controller supported by Intelligent Control Technology Co., Ltd. to verify and improve the feasibility of controller. The results show that, the optimal PID controller designed by GA can track position command rapid.
