For an arbitrarily time-varying system, a series of hankel matrices are established directly from the combined measurements of displacement, velocity and acceleration together with the input excitations, which have been obtained through only one experiment of the system. The varying equivalent state space system matrices of structures at each moment are then identified by singular value decomposition using the forced responses and input forces.
