| Research Abstract |
(1)Drive control achieving minimum losses
An identification method is refined and completed, which can identify equivalent core-loss resistances on the unified mathematical model of AC motors corresponding to eddy current or/and hysteresis loss. In addition to that, for salient-pole permanent magnet synchronous motor, new methods for determining the optimal current command for energy-efficient and wide-speed-range operation are established.
(2)Drive control taking magnetic saturation into account
For cylindrical permanent magnet synchronous motor, a new dynamic mathematical model is established. A new dynamic simulator for the motor is also established based on the model. Further more, a new initial-position method established.
(3)Systems in the D-module
System in the D-module is quit a new concept, which allows to get very efficiently specific effects for three-phase systems. A total of analyses on the systems in the D-module is completed. The analytical results make applications of the systems in the D-module to a variety of three-phase systems possible.
