This dissertation presents how to use the ultrasonic motor as an actuator to suppress the flutter of a two - dimensional airfoil section with a control surface. the ultrasonic motor, which features simple structure, high torque at low speed, small size, low weight and no electromagnetic contamination, is a promising actuator for the flutter suppression of small aircraft
超聲電機以其結構簡單緊湊、轉矩/質量比大、低速大扭矩、直接驅動，動態響應快、斷電自鎖和不產生磁場且不受外界磁場干擾等優點，有望成為一種非常有前途的作動器，用於小型飛機的機翼顫振主動抑制。 -
Surface acoustic wave ( saw ) motor is a novel micro actuator, which generates saw with the electroacoustic transducer and transfers it to the power of saw motor by the frictional force between the slider and the stator
表面彈性波馬達是一種以電聲換能器產生表面彈性波，並通過馬達動子和定子的接觸摩擦將表面彈性波振動轉換為馬達動力的新型執行器。 -
Multiple failures include actuators " failures, actuator and single control surface ' s failures. the former can be detected by local detection, while the latter should be detected by local and global detection together
多作動器卡死組合故障通過相互獨立的局部檢測環節判定；而作動器卡死與單舵面損傷組合故障則需要局部檢測和全局檢測結合來判定。 -
The main contributions of the dissertation are as follows. in chapter 2, the dissertation demonstrates the design of an airfoil model with a control surface driven by an ultrasonic motor as the actuator first, and then presents the experimental modeling of the actuator
論文的主要工作與學術貢獻如下: （ 1 ）設計了以超聲電機為作動器驅動控制面的二維翼段模型，並建立了作動器的傳遞函數模型。 -
The early studies are mostly focused on the method of gluing piezoceramics on structural surfaces, which has some disadvantages such as difficulties to protect the ceramics and the connection wires, bad coupling with only one surface glued on the base materials, low signal - to - noise ratio etc. these problems can be solved using the embedded piezoceramics, and furthermore, the piezoceramics can be placed in the optimal positions, especially in the optimal deepness for the piezo - actuators, according to an optimization algorithm befor e they are embedded, so the actuator effects and sensor signals are thereby enhanced
早期的研究主要集中在表面粘貼壓電片的結構，表面粘貼壓電片具有一些無法克服的缺點。本文著重進行利用埋入復合材料結構的壓電傳感器和壓電驅動器對其振動進行主動控制的相關理論和實驗研究，並介紹其相應結果。埋入型壓電材料的優點主要是能保護壓電傳感器和作動器及其連線、增強壓電材料和基體材料的耦合、優化埋入壓電陶瓷的深度和厚度可增強壓電傳感器的測量信號並提高信噪比等。
