摘要

In this paper, a very simple vector control algorithm is proposed for /spl mu/-based induction motor drives. The proposed method controls the motor torque directly and linearly to achieve instantaneous torque response without oscillation. The merits of this control method include its simple architecture and obviating the coordinate transformation. At the same time, a new space vector-based current controller is proposed to serve as a quick response torque controller of the proposed drive system. In addition to the current error, information on the current error derivative is further employed so that one can take more advantages of adding the zero voltage vector for reducing the switching frequency. As a result, the efficiency can be greatly increased. It is seen that through integration of the above two parts, the proposed drive system is very simple to implement and has very good performance.
