双环(位置环和电流环)自抗扰控制器的设计，以单点悬浮系统为研究对象，采用分级控制策略和非线性自抗扰控制方法。

Based on cascade control strategy and nonlinear auto-disturbance-rejection control (ADRC) method, double loop (position loop and current loop) ADRC was designed for single-pivot levitation system.

而对其中的电流环采用传统的PID算法控制，对于转速环，由于转速受多种非线性因素的影响，因而采用模糊控制算法。

We adopt traditional PID arithmetic to control current loop, and we adopt fuzzy control arithmetic to control rev loop, for rev loop is affected by many kinds of linear factors.
