Abstract
The paper analyzes two kinds of driving mode of piezoelectric injectors ccording to the characteristics of the piezoelectric actuator, then compares the advantages and disadvantages of the fixed duty cycle PWM switching type, variable duty cycle PWM switching and driver-based adaptive current PWM switching type, chooses voltage and current double closed-loop control strategy. The hardware and software design of high pressure common rail piezo injector driving control system were completed, as well as the experiments of different driving implementation were finished based on the designed driving control system. The results show that driver-based adaptive current PWM switching type is able to control the piezoelectric actuator deformation and the strain rate flexibly, ensure the energy distribution in the charge-discharge process of piezoelectric actuator gets more balanced.
