In this work, we study a global output synchronization problem for nonidentical nonlinear systems having relative degree 2 or higher. The synchronization uses a partial projection of individual subsystems into the Brockett oscillators. Our approach is based on output feedback and uses a higher order sliding mode observer to estimate the states and perturbations of the synchronized nonlinear systems. Simulation results are provided to illustrate the performance of the proposed synchronization scheme.
