交流永磁馬達順滑模態控制器之DSP實現

Abstract

在本論文中利用順滑模態控制技術來設計交流永磁式同步馬之速度控制閉迴路架構。將對電流控制迴路設計轉矩電流以及d軸電流之順滑模態控制，以期許轉矩電流以及d軸電流能夠達到期望值，而此種電流控制迴路也將滿足磁場導向控制中解耦合之特性。對速度控制迴路設計速度誤差之順滑模態控制，讓系統之速度軌跡能夠進入順滑平面而達到期望之速度值，在本論文中將會進行模擬與實驗的結果來驗証控制理論之可行性。 在本論文中將會以Turbo C++語言來進行控制器之模擬，在完成模擬之可行性後，將會以DSP晶片所建構之數位控制板來進行實驗的階段，以驗証控制器在實作上之可行性，也將馬達控制之實現帶入至數位化控制的階段。

In this thesis, use sliding mode theorem technique to design the closed loop speed controller for permanent magnet synchronous motor (PMSM) scheme. Designing the sliding mode controller for current loop in inner loop about Torque-current and d-axis current to achieve the desired value.This kind of controller will fit the property of field-oriented control.In speed loop controller, design the sliding function about the speed error and let the speed trajectory put into the sliding surface to achieve the expected value.The results about simulation and experiment are presented to verify the usability about the whole controller. Using Turbo C++ software language to proceed with the simulation. After finished the usability about simulation, use digital control board constructed by DSP chip to proceed with the experiment can be realized in practical.This experiment result will alse lead the motor control into digital control stage.
