摘要

本文主要目的為主要發展壓電致動器在運動平台上之精密定位控制方法，利用基因演算法的原理與運算方式，透過基因編碼、複製、交配與突變等程序，搜尋PID控制器之最佳增益參數值，並結合單晶片微處理機及LC串聯共振之驅動控制器來驅動壓電陶瓷馬達，及配合精密量測感測器，應用於以壓電壓電陶瓷馬達為驅動源之精密定位平台上。而由電腦模擬與實驗結果均顯示，利用基因演算法所設計之PID控制器，能有效改善系統的性能響應，達到快速精密定位控制之目標。

A genetic algorithm is developed for high-speed and high-precision positioning control on a platform driven by piezoelectric actuator in this article. By means of encoding, reproduction, crossover and mutation, a set of optimal gains for PID controller is obtained. The entire system makes use of a single chip processor and a LC series resonant driving control circuitry for piezoelectric ceramic devices in association with precise measurement sensors. The simulation result and practical experiment verify the performance of the proposed control algorithm that is able to achieve the objective of high-precision positioning.
