초록

Generally, the current controller is located inner the whole controller, so the characteristic of the current controller is important in controlling performance of the upper controller. A current control loop in motor control is designed so that it is 10 times faster than the speed control loop of the upper controller. Thus, the current controller with complex control algorithm is not proper. In this paper, the improved current controller using a conventional digital PI controller and feedforward controller for the brushless BC motor is designed.
