| Abstract:The mathematical model of injector solenoid valve was established using Simulink, and the method of current feedback control was applied to research the injector driving control technology. The high and low voltage time-sharing driving circuit was designed with current feedback control technology, and using Multisim to simulate the driving circuit. The simulation results show that the driving current can be adjusted automatically according to the pre-set peak current and holding current feed back circuit. The driving experiment on certain injector were carried out. The experimental result verifies the precision of the model of injector solenoid valve and good performance of driving circuit. |
