摘要:
异步电机在标量控制( VVVF) 下,其转速会随着负载的变化而出现误差,转速控制性能差。针对这一问题,提出了基于矢量控制思想的异步电机滑差补偿法。结合了矢量控制和标量控制两者的优点,在异步电机转子磁链近似恒定的基础上,根据空载励磁电流值来实现转子磁链定向,利用李亚普诺夫理论做稳定性分析,实现异步电机定子电流的励磁分量和转矩分量的分解; 根据转矩分量和滑差的线性关系对转速进行补偿,使异步电机重载情况转速波动不超过1. 5%。通过计算机仿真分析和实验验证了方法的有效性。
Abstract:
 Speed performance of asynchronous motor gets worse as load varies under scalar control ( VVVF) . This paper presents a method based on vector control for the slip compensation of asynchronous motor which combines the advantages of vector control and scalar control. On basis of approximately constant rotor flux linkage of asynchronous motor,rotor flux orientation was realized according to no-load excitation current,and stator current was resolved into excitation component and torque component. The stability was analyzed based on Lyapunov theory. Compensation according to the linear relationship between the torque component and the slip led to a better speed performance under heavy load. Simulation and experimental results are presented in the paper to verify the effectiveness of the proposed approach.
