Abstract:The deep flux weakening (FW) switching point of the interior permanent magnet synchronous motor (IPMSM) is difficult to track accurately. After entering the deep FW region, the current regulator is easily saturated, and the current following capability is poor. Aiming at these problems, a deep FW control of the IPMSM based on the d-axis current error integral regulator (DCEIR) is proposed. Firstly, the deep FW switching point is accurately calculated by using the maximum torque per volt (MPTV) as the limit of … Show more
