根据同步电机dq轴下的方程推导出二相静止坐标系下的方程,求出二相静止坐标下电感与交直轴电感的关系和反电势方程.提出了在二相静止坐标系下,通过反电势强滤波方式求宽范围变频状态的转子位置角的方式,详细阐述了滤波器参数设计的原则,给出了在考虑数字控制器中实现的滤波器参数设计的约束条件.该方案简单可靠,易于工程应用.通过实例仿真和实验验证了该设计方法的可行性.
Abstract
According to the DQ-axis equation of the synchronous motor,the equations based on two-phase stationary coordinates were deduced in this paper.The relationship between the inductances in the two-phase stationary coordinates and the direct axis and quadrature axis inductances was studied and back electromotive force equation was given.The method to find the rotor position angle of the state of wide range frequency was proposed by the way of back electromotive force strong filtering.The principle of filter parameter designing was elaborated and the constraint conditions of this design were given in the considering digital controller.This project is simple and reliable,which is easy for engineering application.Through simulation example and experiment,the feasibility of this design method was verified.
