The state-space representation of an aerodynamic vortex lattice model is considered from a classical, system identification perspective. By the use of an aerodynamic vortex model as a numerical simulator of a wind-tunnel experiment, both full-state and limited-state data or measurements are considered. Two possible approaches for system identification are presented, and modal controllability and observability are also considered. The theory then is applied to the system identification of the flow over a delta wing, and typical results are presented
