For the vibration protection system under study with a controlled dynamic damper, optimal positional control of the intermittent damping process is found.

Using the example of optimizing a chemical reactor, the practical implementation of an approach that made it possible to achieve a balance between product yield, energy consumption, and environmental performance is demonstrated.
