The load disturbance is estimated and compensated by the speed controller, which effectively removes the statictrackingerror that would be caused by the disturbance without compensation.
通过速度控制器对负载扰动进行估计和补偿，消除了负载扰动可能带来的稳态跟踪误差。

Generalized integrator was used to realize staticerror free tracking control of positive and negative sequence current under two-phase static coordinate.
