Abstract
In this paper, a new field weakening algorithm which maximizes the output torque not only in steady state but also in transient state is proposed. Considering both voltage and current limit of system, analytic solutions for optimal torque utilization in field weakening region I and region II are obtained. This algorithm finds optimal currents considering dynamic voltage limit based on flux and speed. So the maximum usage of stator voltage even in transient state results in the maximum torque and fast response time. Simulation and experimental results show the effectiveness of the proposed field weakening scheme.
