Method and device for controlling the angular speed of an electromechanical drive train with little damping. The control of the speed of the load driven in rotation by an electromechanical drive train with little damping, possibly having transmission nonlinearities such as play, without measuring said speed, is accomplished by using an observer in conjunction with a robust CRONE-type non-integer order controller, the physical realization of which is achieved by an integer order controller obtained by approximation in the frequency domain. The device thus provides good damping for the system in the presence of resonance frequencies and excellent robustness, while still allowing a relatively simple adjustment.

A process for estimating the speed of a vehicle or of an assemblage of vehicles, based on measuring the speeds of the mechanically independent wheels, while all the wheels are slipping with respect to the rolling surface, the process includes a step using mechanical and kinematic information characteristic of the vehicle or vehicles.
