Description
vq=R×Iq+ω×Ld×Id+ω×φ ・・・(1)
第1実施形態について、図4〜図6を参照して説明する。第1実施形態では、2台のインバータ60、70は、いずれも角度非同期制御を実行する。すなわち、各インバータ制御回路201、202は、MG80の電気角θeとは非同期のタイミングで電圧指令を更新し、インバータ60、70に出力する。角度非同期制御の例である正弦波PWM制御モードでは、PWMキャリア周期に同期したタイミングで、すなわち所定の時間間隔で電圧指令が更新される。電圧指令の更新周期が例えば200μs程度のフィードバック制御を「高速フィードバック制御」という。
第2実施形態について、図7〜図9を参照して説明する。第2実施形態では第1実施形態と同様に、2台のインバータ60、70は、いずれも角度非同期制御を実行する。また、図7に示すように、例えば第1インバータ制御回路201が高速フィードバック制御を実行し、第2インバータ制御回路202が低速フィードバック制御を実行する。
第3〜第5実施形態について、図10〜図12を参照して説明する。第3〜第5実施形態では、2台のインバータ60、70は、いずれも角度同期制御を実行する。すなわち、各インバータ制御回路201、202は、MG80の電気角θeに同期したタイミングで電圧指令を更新しインバータ60、70に出力する。角度同期制御の例として、電気角1周期に1パルスの矩形波を出力する矩形波制御が挙げられる。矩形波制御では電圧振幅は一定であり、電圧位相のみが制御される。
(a)図13に、各インバータ制御回路201、202における、高速フィードバック制御、低速フィードバック制御もしくはフィードフォワード制御、及び、角度同期もしくは非同期制御の制御方式の組合せをマトリックスで示す。図13中、制御干渉が発生しない組合せを「○」で示し、制御干渉が発生するおそれがある組合せを「×」で示す。(*1)〜(*5)は、それぞれ上記第1〜第5実施形態に対応する。両方のインバータ制御回路201、202がいずれも角度非同期制御で、且つ高速フィードバック制御又は低速フィードバック制御の場合、制御干渉が発生するおそれがある。
201・・・第1インバータ制御回路、
202・・・第2インバータ制御回路、
60・・・第1インバータ、 61〜66・・・第1スイッチング素子、
70・・・第2インバータ、 71〜76・・・第1スイッチング素子、
80・・・MG(モータジェネレータ、電動機)、
81、82、83・・・3相巻線。
