摘要

本文主要研究三相异步电动机的转差补偿问题。降低异步电动机的转差对保持异步电动机在不同频率和负载下的稳定运行具有重要意义。为了减小滑差,采用比较器和PI控制器将转子实际转速与同步转速之差加入到转子转速中。减少的滑移是通过增加转子频率和反馈到输入补偿。在这个项目中使用了两种技术。它们是反馈控制技术和前馈控制技术。这些用于保持感应电动机的恒定速度运行。本课题研究异步电动机驱动开环v/f控制的转差补偿的MATLAB。采用滑差补偿,提高了负载运行时的转速精度。它主要适用于v/f控制技术。

Simulation of Slip Compensation for Induction Motor Drive Using MATLAB
This paper mainly focuses on slip compensation in three-phase induction motor. It is important to reduce the slip of induction motor to maintain stable operation at different frequencies and loads. In order to decrease the slip, the difference of actual rotor and synchronous speed is added to the rotor speed using comparators and PI controllers. The decrease in slip is compensated by increasing the rotor frequency and feeding back to the input. Two techniques are being used in this project. They are feedback control technique and feedforward control technique. These are used to maintain the constant speed operation of an induction motor. This project deals with the slip compensation of open-loop v/f control of induction motor drive MATLAB. The slip compensation is used to improve the accuracy of the speed when the load is operated. It is mainly effective for v/f control technique.
