摘要
采用一种改进的直接转矩控制方法 ,使用无死区时间功率变换器及三点式磁链调节器 ,改变开关控制规则 .给出系统硬件结构和软件设计 ,经过仿真得出逼近的圆形磁链轨迹仿真曲线以及转速和转矩仿真曲线 .通过比较验证说明所设计的系统具有优越的低速性能 .
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.
