| Research Abstract |
This research developed a novel control method for high efficiency drives of permanent magnet synchronous motors. In the conventional method, a pre-calculated look-up table or an approximate equation is necessary for the control. In the proposed method, a relationship between torque and flux linkage is calculated in real time, and thus, the controller can adjust operating point to parameter variation of the motor. Hence, it is expected to achieve high-efficiency and wide-speed range operation by using simple control law.
