Abstract
The research on maximum torque per ampere ( MTPA ) control of interior permanent magnetic synchronous motor( IPMSM) was presented. Based on the IPMSM math model in d-q reference frame, the equations of d, q axis currents and magnetic torque were derived by using maximum principle. Thus, this method realized the IPMSM MTPA control. Under the condition of same magnetic torque, the IPMSM MTPA control could minimize the input current magnitude, decreased the IPMSM power loss and the inverter capacity, increased the system efficiency and improve the dynamic performance of system. At last, the simulation model verified the MTPA scheme above was correct.关键词
