Abstract:The dq current of the high-speed maglev is coupled in synchronous-frame, when working in the double feed mode, the current coupling is severe, which affects the stable operation of the maglev train. The traditional decoupling control strategy is sensitive to parameters, so this paper proposes a current decoupling strategy based on active disturbance rejection control (ADRC). This strategy considers the voltage error caused by current coupling and changes of inductance parameter as system disturbance, then observes disturbances through the extended state observer, and feeds forward the disturbance to compensate the influence of the disturbance on the system. Simulation and hardware-in-the-loop (HIL) experiments demonstrate that the strategy has strong robustness to parameters and it can achieve current decoupling, reduce the current fluctuation of the maglev train during the stator section changeover process, improve system dynamic performance.
