The invention discloses a slip control method, a slip control system and a phase shift filter. The slip control method comprises the steps that low-pass filtering is conducted on slip parameters used for slip control in each period, the value obtained after low-pass filtering is conducted on the current period serves as a current forward-moving pre-slip parameter of the current period, and the value obtained after low-pass filtering is conducted on one or more previous periods serves as a historical forward-moving pre-slip parameter; acquiring historical forward and backward slip parameters of one or more previous periods; subtracting the weighted value of the historical slip parameter after forward movement from the weighted value of the current slip parameter before forward movement and the weighted value of the historical slip parameter before forward movement to obtain a current slip parameter after forward movement in the current period; and performing slip control based on the current forward and backward slip parameters. On the basis of low-pass filtering phase backward shift, a set of filtering algorithm is superposed, and through phase forward shift of the slip parameters, hysteresis in slip control is eliminated, and rapid response of slip control is ensured.
本发明公开滑移控制方法、系统及相移滤波器。滑移控制方法包括:在每个周期对用于滑移控制的滑移参数进行低通滤波,将当前周期进行低通滤波后的值作为当前周期的当前前移前滑移参数,将之前的一个或多个周期进行低通滤波后的值作为历史前移前滑移参数;获取之前的一个或多个周期的历史前移后滑移参数;将所述当前前移前滑移参数与所述历史前移前滑移参数的加权值,减去所述历史前移后滑移参数的加权值,得到当前周期的当前前移后滑移参数;基于所述当前前移后滑移参数进行滑移控制。本发明在低通滤波相位后移的基础上,叠加一套滤波算法,通过对滑移参数的相位前移,消除滑移控制中的迟滞,保证滑移控制的迅速响应。
