With the increasing number of electric multiple units (EMUs) operating in a rail depot simultaneously, low frequency oscillation (LFO) may occur. In this paper, linear active disturbance rejection control (LADRC) is designed for the single-phase EMUs rectifier control. Moreover, Nyquist criterion is adopted to analyze the stability theoretically. Furthermore, the static and dynamic performance of the system based on LADRC is verified through the resistance mutation tests in MATLAB/Simulink comparing with traditional proportional integral (PI), nonlinear PI (NPI) and auto disturbance rejection error PI (ADRE-PI). Finally, the validity of the LFO suppression with LADRC is verified in the simulation.
