A damping system is provided which is a self-adaptive damping system with an energy balance characteristic. The system has a conventional control chain and feedback loop which includes a detection means, an optional corrector, and a controllable damping device. In addition the system further includes an adaptation loop which is at least partly in parallel with the feedback loop and is coupled to and utilizes the information delivered by the detection device. The adaptation loop is coupled to and effects control of the damping device. The adaptation loop includes a comparator, an integrator and two parallel circuits furnishing to the comparator one signal which is a function of the energy of the slow mode of the system to be regulated in the occurrence of the process mode and a second signal which is a function of the product of the energy of the rapid mode and of the relation of the logarithmic decrements of these two modes. The comparator furnishes a result of the comparison to the aforenoted integrator which is connected to the controllable damping device. The invention also provides the method performed by the aforesaid equipment.
