This paper designs a driving control method of electromagnetic metering pump, including the following calculation of the initial pulse number of each step, active degaussing initial current, active degaussing initial time, and the initial duty cycle of the degaussing process according to the system Settings and hardware parameters. This paper realizes the drive control of electromagnetic metering pump and the active degaussing function of electromagnetic coil, which has the characteristics of short degaussing time to meet the high-speed drive. This paper uses MATLAB to simulate and verify and apply in the actual circuit. The drive control method can easily configure the drive parameters of the controller, effectively expand the maximum stroke and maximum pump pressure range, and reduce the design requirements of the pump body heat dissipation structure.
