This paper proposes a hybrid control method of servo motor drives for fast dynamic response and low torque ripple. A duty modulated direct torque control (DDTC) with a variable control period is proposed to achieve a fast dynamic response at a transient-state. Low torque ripple is achieved through the conventional field-oriented control (FOC) at a steady-state. In addition, a smooth transition method from the DDTC to FOC is introduced. Experimental results verify the proposed control method with a surface-mounted permanent magnet synchronous motor (SMPMSM). |
