Consensus Control for a Class of Second Order Nonlinear Systems with Parametric UncertaintyAbstract Position and velocity consensus problems of second order nonlinear multi agent systems are considered in this thesis Distributed adaptive con trollers are developed to tackle with the uncertain parameters Intro ducing new Lyapunov functions global consensus results are achieved without requiring global Lipschitz condition or polynomiality assump tion on the nonlinear functions Speci cally two important class of second order nolinear systems have been investigated in this thesis Euler Lagrange systems and Kuramoto oscillators For a network of uncertain Euler Lagrange agents assuming some known bounds of some param eters distributed adaptive methods are proposed to achieve leader less and leader follower consensus Consensus can be achieved even without velocity information exchange As an interesting application and inspired from the proposed method for the velocity consensus of general nonlinear systems a new controller is designed to solve the challenging problem of global frequency synchronization of second order Kuramoto oscillators with phase shifts Simulations results demonstrate the e ectiveness of proposed method for global frequency synchronization of a network of second order Kuramoto oscillators with phase shifts Keywords Distributed control consensus adaptive control Euler Lagrange sys tems nonlinear oscillators
