摘要
为提升异步电机矢量控制系统的可靠性和减少系统成本,介绍了基于DSP的异步电机无速度传感器控制系统的设计。在异步电机的转子磁场定向矢量控制系统中,为了完成无速度传感器矢量控制,利用基于反电势积分的控制算法对电机的实时转速进行实时估计。通过MATLAB/Simulink仿真研究了反电势积分算法的效果,使用实验室搭建的拖动系统实验平台对算法进行了实验验证。仿真和实验验证了此控制方案具有很好的实际效果。
In order to improve the reliability of asynchronous motor vector control system and reduce the system cost,a speed sensorless control system of induction motor based on DSP is introduced.In the rotor field oriented vector control system of induction motor,the control algorithm based on back EMF integral is used to estimate the real-time speed of the motor in order to complete the speed sensorless vector control.The effect of back EMF integral algorithm is studied by MATLAB/Simulink simulation.Experimental verification of the algorithm is carried out using the experimental platform of the drag system built in the laboratory.The simulation and experiment show that this control strategy has a good practical effect.
