ABSTRACT:
A device for the electronic control of an actuator, particularly for transmission dog clutches. The actuator is controlled by two double-acting cylinders, a translation cylinder and a rotation cylinder. Each of the cylinders is associated therewith a system for noting the position of each cylinder, a control system that provides a digital signal representative of the desired position of each cylinder, a digital comparator for producing an error signal as a difference between the desired position and then the actual position, and a digital regulator of the proportional and derivative type which produces an instruction signal to change corresponding solenoid valve. A microprocessor acts with the digital regulator to produce internal storage and programs.
