  Many coordination phenomena are based on a synchronisation process, whose
global behaviour emerges from the interactions among the individual parts.
Often in Nature, such self-organising mechanism allows the system to behave as
a whole and thus grounding its very first existence, or expected functioning,
on such process. There are however cases where synchronisation acts against the
stability of the system; for instance in the case of engineered structures,
resonances among sub parts can destabilise the whole system. In this Letter we
propose an innovative control method to tackle the synchronisation process
based on the use of the Hamiltonian control theory, by adding a small control
term to the system we are able to impede the onset of the synchronisation. We
present our results on the paradigmatic Kuramoto model but the applicability
domain is far more large.
