英文摘要： Rail transportation equipment manufacturing industry is a strategic industry of the national key support. The traction and control technology of the most core technology is put forward higher requirements with its high development. Emu motors exit time-varying features and switching characteristics in the operation of the traction when speed range change widely. Based on the theory of switching LPV systems, high-speed EMU motor robust control is studied. Considering the parameters section, change rate and relationship between parameters and performance of the system, the project put forward strong tracking filtering delay and multiple model estimation method to identify parameters value. After the values of the parameters identified is introduced into dynamic linear parameter varying Emu motor model, linear parameter varying switching controller is designed. Meanwhile, a linear parameter varying fault model is put forward and active fault tolerant control technology is adopted to maintain the system safe operation while failure occur in the motor.Finally, the inverter space vector pulse width modulation algorithm is optimized. Research subject provides theory support to realize the emu traction drive system of high performance and high precision operation. The project of independent innovation of China railway high-speed train traction drive control has important theoretical significance and engineering application value.
