Abstract
- This paper proposes a maximum torque per ampere control strategy for direct-torque-controlled interior permanent magnet synchronous motor drives. The proposed method is based on the solutions of a quartic equation, a motor model in the d-q rotating frame often used for the synchronous motor controllers, and a well-known equation for maximum torque per ampere control. Therefore, the proposed method does not use a lookup table that depends on parameters of the motor and that has to be created in advance. In addition, the proposed method can use the estimated parameters. Particularly, the variations of the d- and q-axes inductances can be estimated when the inductances are modeled as the functions of the d- and q-axes current. The simulation results validate that the proposed method can achieve the maximum torque per ampere control. In addition, the simulation and experimental results verify the accuracy improvement of the maximum torque per ampere control with the iterated calculation. [ABSTRACT FROM AUTHOR]
