中文摘要 | 由形狀記憶合金(Shape Memory Alloy,簡稱SMA)驅動的X-Y平台,具有設計簡單、耗能少、成本低等特色。本系統有別於一般馬達控制,藉由SMA隨溫度變化而產生形變,進而拉動平台,並利用光學滑鼠的光感測器測量位移量,經由數位訊號處理器運算,以梯度下降法線上調整模糊滑動模式控制器的參數達到最佳的平台軌跡控制。 |
英文摘要 | In this paper, an X-Y platform driven by shape memory alloys is constructed, featuring simple mechanism design, low power consumption and low cost. Shape memory alloy can undergo thermoelastic martensitic transformation by increasing the temperature above a certain level, hence producing pulling force to drive the platform. An optical sensor is used to track the movements of the platform, which are then sent to a digital signal processor. Adaptive fuzzy sliding mode controller, whose parameters are tuned online by the gradient descent method, is employed for optimal tracking control of the X-Y platform. |
