According to the trait of the current feedback loop,it proposes a novel method of designing controllers with the current feedback loop,based on deconvolution.The numerical control scheme was used,and the amplitude of controllers was directly related to the previous tracking eror and the output of the speed loop controller,with the structure of feedback with feedforward.The simulation results show that the controller enables the output of curent loop to track the objective electric curent and that it has such features of smaller overshoot,rapid response speed and robustness.
