A method and an electronic device for compensation of the hysteresis of a pneumatically driven fitting having an electropneumatic valve. The electropneumatic valve is driven by a position regulator and is used in a closed control loop for position regulation of a switching element of an pneumatic actuating drive for operation of the fitting. Hysteresis of the pneumatically driven fitting is compensated for by the position regulator via at least one hysteresis correction factor. The control-engineering compensation for the hysteresis is carried out separately for a first basic case of starting or reversing a switching element and for a second basic case of continuous movement of the switching element, such that a dominant static friction is compensated for in the first basic case and the dominant sliding friction is compensated for in the second basic case, and the pneumatic actuating drive operates the switching element matched thereto.
