Research On High Efficiency Control Method Of Linear Compressor For New Energy Vehicle

With the energy consumption and environmental pollution more and more serious, energy saving and environmental protection have become the common concerns of all countries in the world topic, so new energy vehicles will be the inevitable choice for the development of the car industry. New energy vehicles mainly include hybrid vehicles, fuel cell vehicles and electric vehicles. And electric vehicles can achieve zero emissions and highly resource comprehensive utilization, and it completely get rid of the dependence on oil, so it is the main direction of the development of new energy vehicles industry.Compressors as one of the vehicles’important part, its performance plays an important role in the development of new energy vehicles. Compressors using in conventional vehicles are driven by the pistons, which are driven by the crank connecting rod mechanism and the crank connecting rod mechanism output the engine rotation movement into linear motion. The compressors using in conventional vehicles are not suitable for new energy vehicles because of its huge volume, low transmission efficiency and large energy consumption. So we must develop a new compressor, which is electric drive, high efficiency and energy saving and suitable for new energy vehicles, namely linear compressor. Compared with the traditional compressor, linear compressor does not have the crank connecting rod mechanism and its volume, quality and noise are greatly reduced.The object of this research is the principle prototype of permanent magnetic moving coil type linear compressor. Firstly, through the research of this principle prototype, the mathematical model is established. Secondly, to establish this principle prototype simulation model and control strategy based on the principle of Push-to-Push in Simulink. Thirdly, through the genetic algorithm to search points, which make efficiency of the principle prototype reaches the maximum value. Finally, through the experiment to verify the feasibility of the control strategy.
