Abstract:

In the control of AC motors, the inverter output voltage is difficult to be accurately controlled due to the inverter disturbance, which affects the output torque and efficiency. The inverter disturbance has complex nonlinear characteristics, so it is difficult to be well compensated by simply using the inverter interlock time. Consequently, offline inverter disturbance calibration is required. In this paper, an observer-based inverter disturbance self-learning and compensation method is implemented. Inverter disturbance characteristics can be accurately obtained without offline calibration. At the same time, high-performance inverter disturbance compensation is realized. By implementing proposed compensation methods to a 1 kW prototype permanent magnet synchronous motor, the performance of the inverter disturbance self-learning and compensation are both verified.
