Current Control Calculation and Simulation Analysis of Urban Railway Traction System

Wang, Yilin

In the urban railway industry, the stability and reliability of the permanent magnet motor control in urban railway vehicles is very important to the traction system and the overall vehicle operation. Control, so that the output of the inverter gets a series of pulses with the same threshold, and these pulses can be used to replace the sine wave and the desired waveform. Then input an AC current of a certain frequency into the permanent magnet motor. Among them, the current given closed-loop control is particularly important in the case of different rotational speeds in the permanent magnet motor algorithm control. This paper proposes maximum torque current ratio control (MTPA), field weakening control and maximum torque voltage ratio control (MTPV), and uses Simulink software to model and simulate simulation waveforms to verify the stability and reliability of the hybrid modulation output proposed in this paper.
