| 摘 要： | 主要分析了无速度传感器的直接转矩控制,采用了基于定子磁链的矢量角和转子磁链的矢量角的两种速度估计方法.仿真结果表明,当电机稳步运行时,两种估算方法都能准确的估算转速.然而,基于转子磁链矢量角的速度估计算法较能使电机的在动态过程中稳定运行,并具有良好的精度.仿真结果也验证了文中采用的转速观测算法的正确性和可行性.

| Abstract: | The paper mainly analyzes speed-sensorless direct torque control,useing two kinds of speed estimator:one is vector angle based on stator and the other based on rotor flux.Simulation results show that when the motor is running steadily,the two estimation methods can accurately estimate the speed.Yet,the speed estimation method of rotor flux vector angle enables the motor runs more stably in a dynamic process and has better accuracy.The simulation results also verified the correctness and feasibility of speed... |
