Maximum torque Per Volt control strategy for PMSM under flux-weakening operation
摘要
Abstract
Aiming at the issue of inaccurate current trajectory planning during deep flux-weakening operation of permanent magnet synchronous motors(PMSMs),which leads to reduced torque capability,this paper proposes a novel Maximum Torque per Voltage(MTPV)flux-weakening control strategy.The method enables proportional and synchronous adjustment of the id and iq reference values in the MTPV region,achieving high-precision current trajectory planning.Experimental results demonstrate that the proposed control strategy effectively extends the flux-weakening speed range of the motor and enhances torque output capability during flux-weakening operation.关键词
