摘要

收起

采用间接矢量控制时，感应电机的输出转矩易受转子时间常数变化的影响，为了提高电机的转矩控制精度，需加入转子时间常数在线校正算法。现有的参数校正算法大多依赖于准确的电机数学模型，会受到模型参数误差及其他非理想因素的影响，难以保证输出转矩的精度。针对上述问题，在传统基于无功功率校正转子时间常数算法的基础上，考虑了实际系统中无功功率的计算误差，提出1种对无功功率计算误差进行标定和补偿的方法，能够将感应电机输出转矩误差从4%减小至1%以内，并通过实验验证了所提方法的有效性。

Under the indirect vector control, the output torque from an induction motor is easily affected by changes in the rotor time constant. To improve the torque control accuracy of the motor, an online correction algorithm for the rotor time constant is necessary. However, the existing parameter correction algorithms mostly rely on accurate mathematical models of the motor, which are susceptible to model parameter errors and other non-ideal factors, making it difficult to ensure the accuracy of output torque. To address these issues, based on the traditional reactive power-based rotor time constant correction algorithm, the calculation errors of reactive power in actual systems is considered, and a method for calibrating and compensating for reactive power calculation errors is proposed. This method can reduce the output torque error of induction motors from 4% to less than 1%, and its effectiveness was verified by experimental results.
