The simulation model of pmsm close - loop control system is presented based on pwm inverter model and switching vector table model set up by the author and pmsm model in matlab . the model is proved correct from the simulation result 然后在自行構(gòu)造逆變器,開(kāi)關(guān)電壓矢量表等模塊的基礎(chǔ)上,利用matlab中的永磁同步電機(jī)模型,實(shí)現(xiàn)了永磁同步電機(jī)閉環(huán)控制系統(tǒng)的仿真模型,仿真結(jié)果驗(yàn)證了方案的正確性。
