Research Electric Permanent Magnet Motor Vehicle Control System

In recent years, with the rapid socio-economic development, the number ofmotor vehicles in order to fuel the rapid growth of energy also, motor vehicle exhaustemissions to the environment caused a lot of pollution, such as the past two years hazedays, which are on the human body health posed a grave threat, and traditionallocomotives and other transportation equipment are based on the fuel-to-energy,which also resulted in the consumption of oil in recent years, with the increasing carownership increases, which is the world’s one reason oil prices have been high.Battery-electric vehicles is to provide energy, so it is an efficient, clean andsustainable development to meet the transport, therefore, the development of electricvehicles, it is very important.Currently, the electric drive motor vehicles used for the permanent magnetbrushless DC motors, permanent magnet brushless DC motor in this article from thedevelopment machine, discusses its structure and composition, operation principle andcontrol technology. Combination of permanent magnet synchronous motor (PMSM)operating principle and characteristics, leads vector control, vector control provides asolution for the permanent magnet synchronous motor torque and flux decoupling,succeeded him in order to understand the equivalent AC motors Reed DC motors, ACmotors simplified model is a combination of a single stator and rotor windings, so thatpeople freed from the actual three-phase stator and rotor windings as well as thetraditional model.According vector algorithm, using MATLAB/SIMULINK simulation modulefor PMSM control system modeling and simulation, analysis algorithm derivedselected program control is very good. Combined market electric vehicle controller,this system on the microcontroller to select the ST has introduced a32-bit chipSTM32F100. STM32F100microcontroller is based on the breakthrough ARMCortex-M3core, very suitable for control systems, micro-controller chip and controlalgorithms designed Finally, choose the appropriate software section.
