Zusammenfassung: | The embodiment of the invention discloses a hydraulic proportional electromagnetic valve control method and device and a storage medium. The hydraulic proportional electromagnetic valve control method comprises the steps that a preset superimposed current array and target current are obtained, and a feedback current array is collected; performing PID calculation on the feedback current array and the target current to obtain a first duty ratio; correcting the resistance of the hydraulic proportional electromagnetic valve according to the feedback current array and the target current to obtain the corrected resistance of the hydraulic proportional electromagnetic valve; obtaining a second duty ratio according to the first duty ratio, a preset superimposed current array and a hydraulic proportional electromagnetic valve correction resistor; and the hydraulic proportional electromagnetic valve is adjusted according to the second duty ratio. According to the scheme, through double-closed-loop control and correctio |
