磁浮列车悬浮系统的双环自抗扰控制

Double Loop Active-Disturbance-Rejection-Controller for Levitation System of Maglev Train

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。ADRC的参数整定通过建立开环系统和线性PD控制的闭环系统得以实现。仿真结果表明,自抗扰控制的快速性、鲁棒性、适应性和克服大扰动能力均明显优于经典PID。

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. The ADRC parameter setting was achieved by setting up the open loop system and the closed loop system using linear PD control. The simulation results showed that ADRC owned better dynamic performance, stronger robustness and adaptability than PID method.
