Research On The Asynchronous Motor Of FOC Control Based On AMESim-Matlab/simulink Simulation

Recently energy shortage and environmental pollution are more serious. It makesthe automotive industry develop towards energy-saving and low-emission direction. Atthe same time there has been no breakthrough in the electric car battery problem whichmakes hybrid electric vehicle (HEV) be the best choice to ease pollution and energyconsumption, and it is being a new hot spot in the study of the development of domesticand foreign cars.Compared with conventional cars, hybrid cars composed of a new source of power:the engine-generator sets and batteries are used to store energy. In this paper, athree-phase asynchronous motor is selected as the object to be controlled, and vectorcontrol method is used to control the program. This paper is mainly about the parallelhybrid car to start with a three-phase asynchronous motor. Firstly established amathematical model of the induction motor, and introduce the complex decouplingcalculation involved in controlling Asynchronous motors, and then build amathematical model of the induction motor in the two-phase rotating coordinate systemso that it can be ready for a follow-up study.Matlab/Simulink software is utilized to build a simulation model of the inductionmotor vector control, vector control algorithm has the advantage derived from thesimulation experiment that the presence of two current loop is better for motor control,but a large number of coordinate transformation, decoupling and other sectors make thesystem generate greater fluctuations during operation mutation, and also takes a longtime to recover.Simulink simulation model has been set up. Then a Kalman speed sensor link isadded according to the need to improve the system. After expounding the principle ofKalman filter, the vector control system based on Kalman filter algorithm in Simulinkis built as a model, the motor of the speed achieved speed sensor-less control. Thesimulation results also verified the validity of the method.As used in this article is a pure idealized motor model in Simulink, to build closer to the real, this paper introduces AMESim simulation software to simulate a model inAMESim instead of the former idealized one in Simulink. And achieve Co-simulationof AMESim/Simulink. Simulation results show the effectiveness of the control strategy.
