The simulation of permanent magnet synchronous motor control system for electric vehicle
Abstract: This paper illustrates the research background and significance of the subject. It analyzes the development of electric vehicles in China and some foreign countries and proves the superiority of the electric cars and the necessity of developing electric vehicles. Also it forecasts the development trend of the electric vehicles in the future. It analyzes the characteristics of the electric cars and analyzes the special characteristics of the electric motors. This paper discusses the mathematical model and control strategy of permanent magnet synchronous motor and introduces the structure and characteristics of the permanent magnet synchronous motor. The key is to make a description of the spatial voltage vector modulation SVPWM technology and
coordinate transformation， and the simulation model of the permanent magnet synchronous
motor vector control system is set up in the Matlab/Simulink environment. It introduces the function of every simulation model and it adds some disturbances to the system after finishing adjusting the PI parameter to make the system stable in order to simulate electric vehicles in running status under different working conditions.
