A control device for internal combustion engines serves to maintain selectable speeds at a constant value. The control device comprises an actual value-desired value comparison stage for the speed, at least one integrator, as well as storage capacity for the integrator value. The engine has a speed device and within a selectable speed range of the engine, the speed device operates in accordance with its function. Outside of the selected speed range, particularly at higher speeds, the integrator serves as a storage device so that when the speed again enters the control speed range, the stored value serves as a starting point for the renewed control operation. In this way, a rapid control action is insured upon each re-entry into the control range, besides providing an exact control operation within the range.
