三相永磁同步馬達之線圈開路故障偵測及其過渡控制

Abstract

本論文以FPGA(Field Programmable Gate Array)為控制器，描述以單組反流器供電實現三相永磁同步馬達之線圈開路故障偵測及過渡控制。首先從分析三相馬達的等效模型開始，接著利用數學推導結果設計出控制架構，並討論線圈開路故障偵測與過渡控制架構。本論文以平均電流偵測法與電流餘值偵測法來實現故障偵測，探討兩種不同的偵測技術之錯誤偵測情況與其偵測速度，再進行模擬與實作來驗證三相永磁同步馬達之線圈開路故障偵測與過渡控制的可行性，並且比較兩種故障偵測技術之適用情況。

This thesis presents the implementation of the open-winding fault detection and it’s drive-through control for one three-phase Permanent-Magnet Synchronous Motor(PMSM) fed by voltage-source-inverter(VSI) in a FPGA-based system. From the equivalent model of the Three-phase PMSM, then we use conclusion of the mathematical derivation to design the control architecture and discuss the architecture of open-winding fault detection and driving-through topology. This thesis presents the average current detection method and the current residual value detection method to achieve fault detection, and explore two different detection technologies to the error fault detection and the fault detection speed, then the simulation and implementation to validate the feasibility of the open phase fault detection and control for PMSM. Finally, a comparison between the advantages and disadvantages of the two fault detection technologies.
