A class of robust identification problem based on dynamic neural network for unknown nonlinear multivariable systems is studied. Robust transfer law with protection strategy is obtained by Lya-Punov stability theory. It is proved theoretically that the identified system is robust and stable, and the identification error converges to a stable region dynamically according to modeling errors and unmodeled dynamics. The strategy is characterized by the fact that it does not require off-line learning and does not require the state of the object to be completely measurable. The simulation results verify the validity of the proposed dynamic network robust identification strategy
