In particular, the exosystem dynamics are assumed to correspond to harmonic oscillators with unknown frequencies.Cooperative output regulation is achieved by designing, for each system in the network, fully distributed adaptive controllers, i.e. requiring no knowledge of the structural eigenvalues nor initial stabilizing control law.
