| Abstract |
Using coordinate transformations technique is a
conventional method in BLDCM drives, but the amount of
calculation increased in coordinates conversion. This paper
presents experimental results using our proposed simple direct
sine-driving method of brushless dc motors (BLDCMs) 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. 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. Some
considerations compared with conventional driving method will
be point out from experimental results. The priority in memory
resource and executing speed will be discussed, many interesting
results have been obtained, and new features will be pointed out. |
