关于矢量控制电流环复合控制的应用设计

作为以永磁同步电机为执行电机的交流伺服系统来说,其电流控制环是一个内环,它的性能指标好坏,特别是动态特性,将全面影响速度环和位置环,从而影响整个伺服系统,本文以抑制同步电动机的反电动势为目标,采用电压前馈控制电流环,以克服反电动势的影响,同时配合PWM逆变器过调制控制,使电流控制环的动态性能得到改善,为交流伺服系统中速度控制和位置环控制,打下了良好的基础,并以相关的仿真和实验加以验证.

An application design for according to synchronous electric motor vector of magnetism measuring controlling the electric current wreath reuniting the control

The conduct and actions says regarding synchronous electrical engineering of magnetism as the servo system of exchanges to carry out electrical engineerings,and the control wreath of its electric current is an inside wreath,its function index sign,especially dy- namic characteristic of quality,will completely affect the flat- out wreath with the position wreath,from but whole of influence the dy- namic function for influence for versa electromotive force for servo system,this text with repressing the synchronous electric motor is target,adopting ex- make a present of electric voltage controlling electric current wreath,then overcoming the versa electromotive force, at the same time match withing the PWM athwart changing the melody system control,making the electric current controlling the wreath get improvement,for servo system of exchanges the speed control to control with position wreath,and lay to descend the good foundation,and combine with related imitate true with experiment to take into the verification.
