Beschreibung
Zusammenfassung:	The invention concerns a method and a device for controlling the angular speed of an electromechanical chain with low damping. Speed control of a load (10) driven in rotation by an electromechanical chain with low damping, possibly having transmission nonlinearities such as clearances, without measuring said speed, is provided by jointly using an observer (18) and a robust corrector (20) of non integer order, of the CRONE type, whereof the physical execution is provided by a corrector of integer order, obtained by approximation in the frequency domain. The device thus provides proper damping of the system in the presence of resonant frequencies and excellent robustness, while enabling a relatively simple adjustment.
