| Abstract: | A new improved control method is suggested. Improved inverter and three point flux regulator are used. Switching rule is also changed. The hardware structure and software design are given, and the approximate circle flux trajectory, the speed curve as well as the torque curve are presented through simulation. The system is shown to be of fine low speed performance by comparison. |
