Abstract
In this paper, a reference stator flux linkage calculation method is proposed for realizing maximum efficiency operation in direct-torque-controlled interior permanent magnet synchronous motor (IPMSM) drives. The proposed method is based on the solutions of a quartic equation, a motor model in the d-q rotating frame widely used for synchronous motor controllers, and a well-known equation for maximum efficiency operation. Therefore, the proposed method uses neither any approximation function nor any look-up table that depends on the parameters of the motor, which has to be created in advance. Simulation results validate that the proposed methods can achieve maximum efficiency operation in IPMSM drives.
