Abstract

Using coordinate transformations techniques are conventional method in brushless DC motor (BLDCM) drives, but it needs more computational resource in coordinate conversions. In this paper, we propose a new control method of BLDCM based on "Internal Model Principle (IMP)". Considering the desired current in driving BLDCM is sinusoidal waveform, it is possible directly using IMP in current control loop. First, we introduce a control strategy based on IMP and verify that the current steady-state error can be completely eliminated. Then the design method of the current controller parameters is discussed. Many interesting simulation results have been obtained.
