The Controller Design of the Permanent Magnet Synchronous Drive Using a Inverter with Phase Compensator

위상보상기를 가진 인버터로 구동되는 영구자석형 동기전동기의 제어기 설계

The computer simulation of speed and phase control system has been carried out in this study. The load of permanent magnet type synchronous motor is not constant in this system. The cost function method has been used in obtaining the optimal gain of PI controller and the rotor position angle of phase controller has been compensated depending on the load and speed variation. This analysis also shows that the current of d-axis component is zero under the variable a load conditions and the torque per unit current can be maximized.
