摘要
在某些工况下,电机的负载转动惯量将是时变的,为了能随着负载转动惯量、阻尼系数的变化同步地调节PI参数从而提高三相永磁同步电机的控制性能,需要在线的估计系统的转动惯量和阻尼系数。文章提出了一种用最小二乘法实现的在线的转动惯量以及阻尼系数的辨识方法,并在Simulink中进行了仿真验证。
In many different situations,the inertia and damping will change as time goes on.In order to adjust the PI parameters with the changing inertia and damping so that the control performance can be improved,real-time identification of the PMSM's inertia and damping is indispensable.This paper presents method of a real-time identification of the PMSM's inertia and damping in base of least square method.Then the feasibility of the method is proved by simulation in the simulink.
