摘要
交流调速中直接转矩控制具有坐标变换运算量小和受电机参数变化影响小的特点.直接转矩控制与模糊控制和无速度传感器相结合会使系统性能进一步提高并增强了实用性.给出了一种方案.仿真结果表明此方案可行.
Direct Torque Control(DTC) has the advantages of less reference frame commutation-computation and less influence by motor parameter variations in AC drives system.An improvement performance and application of the drive system can be obtained by the combination of DTC,fuzzy control and velocity-sensorless control.In this paper, a resolution has been introduced and simulations have been carried out to validate the proposed method.
