Abstract: The invention relates to a method of controlling a dog clutch (8.1, 8.2) by an DC motor (15) configured to move the dog clutch (8.1, 8.2) via an actuator arm (20), the dog clutch (8.1, 8.2) comprising at least one gear (21, 22) having one or more dogs (21.1, 22.1) configured to engage one or more dogs (23.1, 23.2) of a sliding sleeve (23), the method comprising supplying the DC motor (15) with a pulse width modulated voltage having a duty cycle which is provided by a control algorithm (10), the control algorithm (10) comprising a trajectory planner (11) generating a desired position of the actuator arm (20) based on a 4th order trajectory planning algorithm and a motion controller based on the sliding mode theory for tracking the desired arm position.
