ò The time-domain, observer-Kalman filter/eigensystem realization
algorithm is successfully applied to the problem of generating
a minimal state space model realization from a non-linear Lynx
helicopter model. A linear realization is generated which gives a
better representation of the non-linear model than that obtained
using small perturbation linearization methods. The approach can
be used to extract an unstable model from the flight data of a
closed-loop stabilized system, even when the feedback dynamics
are not precisely known.
