摘要

本論文目的為設計製作壓電陶瓷致動器之驅動控制器。為因應不同壓電致動器之應用與使用需求，本研究製作頻率可調變之驅動電路，改良傳統式專用致動驅動器之限制，構想一種泛用型壓電陶瓷驅動器之架構，因應各類型壓電陶瓷材料廣泛之驅動應用。
此泛用型壓電陶瓷驅動器是以一八位元單晶片實現頻率可程式脈波寬度調變換流器設計。在硬體部份，將原來需要多組電源的架構改良為僅需三組電源，並建立數位監控系統，可做多項控制調整及保護措施，並依應用軟體設定參數為閉迴路控制之方式製作，而在軟體方面，設計人機界面讓使用者可從電腦線上設定驅動器控制參數以及控制模式，並修正取樣頻率改善其控制響應。
本研究提出三種以PWM方法所發展之驅動控制方式，設計製作驅動電路，並針對全橋式MOSFET觸發電路、延遲分相、保護電路等功能電路，提出不同的製作方式並加以研究分析，得到實現數位式頻率可調變壓電驅動器之控制系統。經實驗分析證明其設計驅動電路方法配合所使用之單晶片可將頻率規劃可調整，且無需更改線路，其所設計之驅動控制電路亦可適用於其它頻率操作之各類馬達系統中。

Driving controller design for piezoelectric actuator is presented in this article. To support the various operating frequencies for different applications the programmable driving circuit is proposed.
An 8-bit single chip is used to design the inverter of programmable pulse width modulation. On behalf of the hardware, the major improvement is to reduce the need of power sources to only three sets. Also, a digital monitoring system is built to provide multi-purpose of regulation and feedback control. On behalf of the software, a man-machine interface is designed by LabVIEW to provide the environment of parameter and control mode setup and sampling rate change.
Three types of driving control methods are developed based on PWM in this study. Full-bridge trigger circuit, phase delay circuit, and protection circuit etc. are investigated and verified the functions. Via practical experiment, the designed driving circuit embedded on such cheap 8-bit single chip is able to achieve the objective of digital and programmable pulse modulation. Such a device is also suitable for other applications of motor control.
