本文提出了引入电流内环负反馈的控制方法，分析了电流内环对系统响应速度及系统稳定性影响，并建立单自由度磁浮双闭环控制系统，通过系统脉冲响应论证了电流反馈对系统动刚度及系统临界转速的影响。
In this paper, the control method of negative feedback of inner current loop is introduced. The influence of current inner loop on system response speed and system stability is analyzed. A single degree of freedom maglev dual closed-loop control system is established. The impulse response of the system is used to demonstrate the effect of current feedback on system response Stiffness and critical speed of the system.
