基于转矩变化估算的无刷双馈电机直接转矩控制

在研究无刷双馈电机直接转矩控制调速系统的基础上,利用Matlab/Simulink软件建立无刷双馈电机的仿真模型。结合电机本身特性和直接转矩控制转矩脉动大等特点,运用一种通过估算转矩变化量来实现转矩估算的闭环控制方法进行控制。通过仿真验证该方法能有效地减少转矩脉动,具有良好的动、静态性能。

Direct Torque Control of Brushless Doubly-fed Machine with Torque Variation Estimation Control Strategy

This paper studies the direct torque control of brushless doubly-fed motor machine.By taking advantages of Matlab/Simulink to build electromagnetic torque,and combined with features of motor and direct torque control,the closed-loop characteristics are simulated.This system shows that the torque estimation could reduce the torque ripple and has good dynamic and static performance.
