异步电动机直接转矩控制系统的研究

摘要

This paper introduced a asynchronous motor coutrol system of research process. The number turns a control to turned to lay good hardware foundation for high performance and made to adjust soon equip of the function is greatly exaltation,in the meantime make to adjust soon equip of the physical volume is smaller,the weight is lighter. It is direct rightness of to directly turn a control negative change the switch appearance of machinc carry on the best control to acquire the high dynamic state function of the turning. This control system of turning to respond is quickly, restriction at a clap in,and have no super adjust,is a kind of have high quiet,the dynamic state function of the exchanges adjust soon a method.%介绍了异步电动机控制系统的研究过程.数字化控制为高性能化奠定了优良的硬件基础,使调速装置的性能大为提高,并且使调速装置的质量更轻、体积更小.直接转矩控制系统加入了速度环,对速度进行了有效控制.在采取了抑制转矩脉动的策略后,有效地降低了转矩脉动.数字信号处理器的快速响应速度和直接转矩控制直接简单的控制方式,使得异步电动机的调速系统得到了很好地改善.
