Abstract: In a process for controlling an actuator which can be adjusted by means of a proportional valve, the proportional valve is controllable by means of two control magnets with control pulses acting in opposite directions. A phase angle between the control pulses is varied as a function of at least one control variable (command variable, correction variable or difference between the amplitudes or pulse durations of the control pulses), i.e. it is reduced as the control variable increases. This measure prevents undesired vibrations of the actuator and resulting noises.
