摘要
本研究針對以往發展之壓電陶瓷馬達伺服驅動控制電路予以改良，包括增大功率設計以及緩衝電路設計，並解決推動較大負^(多顆壓電馬達)時所產生之壓電效應的影響，及解決通訊命令干擾之問題，在電路中加入伺服控制模組以增加電路系統之穩定性及對電腦端的通訊能力。 驅動電路分兩部分組成:前端為伺服控制模組與推挽式升壓電路，後端為全橋式換流諧振輸出。其中伺服控制模組以單晶片為設計核心，根據馬達之作動原理與開關元件之切換特性設計步進控制及電壓回授控制。橋式電路設計中，加入低損耗緩衝電路，以得到低雜訊的交流訊號，並配合電感、電容及壓電馬達本體設計諧振電路以得到馬達良好之致動效果，經實驗驗證該設計可滿足功能需求。

Based upon the previous circuitry design, the focus of this article is to improve its performance by re-designing the power amplifier and the Snubber circuit for driving more load output requirement (more motors) and reducing the noise effect of the piezoelectricity and solving the interference problem in communication. Also, a servo control module is developed and implemented in the driving circuitry in order to increase the system’s stability and steadiness. The drive circuit is comprised of two parts: one is the servo control module and push-pull DC converter, the other one is the full-bridge resonant converter. By using a microchip, servo controller is developed to accomplish stepping control and voltage-feedback control design based on the motor’s driving performance and the switching characteristics of the Full-bridge converter. In Full-bridge converter, Snubber circuit is used to obtain less-noise AC signal, and associated with the inductance and capacity resonant circuitry is designed. Through practical experiment, the proposed circuitry design is verified can provide satisfactory function requirement for driving the piezoelectric motors.
