Synchronization analysis and design problems for uncertain time-delayed high-order complex systems with dynamic output feedback synchronization protocols are investigated. By stating projection on the synchronization subspace and the complement synchronization subspace, synchronization problems are transformed into simultaneous stabilization problems of multiple subsystems related to eigenvalues of the Laplacian matrix of the interaction topology of a complex system. In terms of linear matrix inequalities (LMIs), sufficient conditions for robust synchronization are presented, which include only five LMI constraints. By the changing variable method, sufficient conditions for robust synchronization in terms of LMIs and matrix equalities are given, which can be checked by the cone complementarily linearization approach. The effectiveness of theoretical results is shown by numerical examples.
