摘要：
For the self-developed piezoelectric injector and actuator, a eompensalion control slrategy based on voltage feedback was designed, a six-stage circuit driving mode was adopted, and the closed-loop compensation control of the driving voltage at both ends of the actuator inside the piezoelectric injector, charge and discharge process based on triangulär waveform driving current were realized. ft improved the utilization rate of circuit energy and reduced the peak current. At the same time, the drive circuit was tested. Test shows that the charging time is shortened by 0. 06 ms, the discharge time is slightly shortened by 0. 01 ms, the minimum pulse widlh for the actuator to reach the maximum displacemenl is shortened to 0. 3 ms, and the peak current is reduced by 3 A, which verifies that the drive circuit has improved in response speed and safety. © 2024 National University of Defense Technology.
