In this paper, an interaction balance coordination algorithm of integrated system optimization and parameter estimation for nonlinear discrete dynamic large scale system is introduced. For nonlinear discrete dynamic large scale system in which molel reality difference exits, a double loop iterative algorithm, which coordinates in upper level and integrates system optimization and parameter estimation in lower level, is obtained by combing dynamic integrated system optimization and parameter estimation with interaction balance method. The correct optimal solution of real system in which molel reality difference exits can be obtained from system model by iterative solution. The efficiency and applicability of this algorithm are demonstrated by simulation results.
