| Abstract |
This contribution presents two controllers for the permanent magnet synchronous motor (PMSM) drives. The low-cost analog controller, containing also discrete components, implements the control of the motor current. In order to obtain the better drive performance, especially to reduce the torque ripple, the controller based on the digital signal processor (DSP) has been developed. It implements the torque control using the field-oriented control (FOC) method. Both control circuits have been examined, and the results are shown to demonstrate the improvement of the dynamic behavior of the motor. Some software problems, e.g. synchronization of the different control tasks, are discussed. |
