Control method, control system and electric valve

Abstract

The invention discloses a control method, a control system and an electric valve. The control method comprises the steps that an actually-measured set parameter curve is acquired; a required set parameter curve is acquired; the actually-measured set parameter curve and the required set parameter curve each comprises a corresponding relation between a position of the electric valve and set parameters; the actually-measured set parameter curve and the required set parameter curve are fit to acquire a position mapping curve; the position mapping curve comprises a corresponding relation between an actual position of the electric valve and a required position of the electric valve, and a difference value of the set parameters corresponding to a horizontal coordinate and a vertical coordinate of each point on the position mapping curve is smaller than a set difference value; a set required position is obtained according to the required set parameters and the required set parameter curve, and a set actual position is acquired according to the set required position and the position mapping curve; and the electric valve is controlled to run towards the set actual position of the electric valve. Therefore, the precision of a control process of the electric valve is improved.
