摘要: 针对电流反馈环的特点,在保持电流环不变的前提下,提出了一种基于反卷积计算的控制器设计方法.该方法采用数字控制算法,每一时刻控制量的大小与前一时刻跟踪误差以及速度环控制器的输出大小直接相关,具有反馈叠加前馈的结构形式.仿真结果表明,该控制设计方法能够使电流环输出有效地跟踪输入目标电流,且具有超调量小、响应速度快、鲁棒性强等优点.

Abstract: 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.
