The invention relates to a method for controlling a braking system for motor vehicles comprising a hydraulically actuatable wheel brake which can be actuated by an electronically controllable pressure supply device that comprises a cylinder-piston arrangement with a hydraulic pressure chamber, the piston of which can be displaced by an electromechanical actuator such that a pre-defined desired pressure value can be adjusted in the hydraulic pressure chamber, a position of the pressure supply device being detected, and an actual pressure (Pv, Ist) of the pressure supply device being determined by means of a measurement device. In order to allow braking pressure to build dynamically at low or medium desired pressure values, manipulated variables (omega Akt, soll, MAkt, soll) are formed for the electromechanical actuator (1) on the basis of the pre-defined desired pressure value (Pv, soll) and of an actual pressure value (Pv, Dach), the actual pressure value (Pv, Dach) being determined on the basis of the desired pressure value (Pv, soll) by weighted addition of the actual pressure (Pv, Ist) and of a model pressure (Pv, Mod) calculated from a current position (XAkt) of the pressure supply device.
