摘要

為有效降低傳統燃油車輛二氧化碳排放與節省怠速之引擎油耗之油電混合複合動力車，其中輕混複合車增加之電動動力(含電池)的成本較低且可有效地提高燃油效率，本文是以用於輕混複合車之皮帶傳動一體化啟動馬達與發電機(BSG)作為研究主軸，調控感應電機以提供輕混系統所需之啟動、助力與發電等功能。其中，前兩項是將感應電機操作於馬達模式而後者為發電模式。
所提架構是以間接磁場導向控制為核心，首先對感應電機進行電氣參數量測與分析，隨後以最大輸出轉矩調控來啟動引擎，當引擎點火後感應電機隨即進入發電模式，此時將依據整車系統之需求進行定電流發電。由於具渦輪增壓裝置引擎於中低速之動力不足，因此可經由感應電機之高頻寬轉矩控制來提供加速之助力。另外，為避免BSG高壓電池因故障而無法發電，本文亦提出以12V低壓電池供電，在較低之磁化電流與電壓下進行發電之控制策略。
最終，以TMS32028035微處理器作為控制核心之驅動器，以一只三相永磁同步電動機模擬引擎以驗證所提感應電機之控制策略。

In order to reduce the emission of carbon dioxide and improve the fuel consumption of conventional ICE vehicles, hybrid vehicle is one of the best solutions. Among the hybrid vehicles, mild-hybrid vehicle can improve fuel consumption effectively and achieve the goal of lower price. Hence this thesis is based on mild-hybrid vehicle’s belt integrated starter and generator (BSG), which is based on induction machine, to reach the key functions of cranking, power boosting, generating and regenerative braking. Among the functions, the first and second are operated in motoring mode and the others are operated in generating mode for the induction machine.
The proposed control structure is based on indirect field oriented control. Measuring and analyzing the electrical parameters of induction motor are necessary in the first part, then using torque control to yield the maximal torque for cranking the engine at idle mode. When the engine starts up, the induction machine will change into generating mode immediately and generate constant current based on the requirement of vehicle. Since the engine with turbocharger can’t provide enough torque in the low and medium speed, therefore the induction machine can provide instantaneous accelerate torque with high bandwidth. In addition, this thesis also proposes a method to avoid the induction machine can’t provide generating power due to failure of high-voltage battery. A careful control of both magnetizing current and generated voltage let the induction machine be in generation mode using the 12V battery to provide stable power.
Finally, the motor drive with a DSP TMSF320F28035-based control stage and power stage is built. A three-phase permanent magnet synchronous motor is used as the engine simulator to validate the proposed induction machine control strategies.
