Abstract : The extended Kalman filter was used to estimate three pilot parameters, a pilot gain, lead time constant, and pure time delay. These parameters were estimated by defining them as states in an augmented state vector. The pilot model used consisted of a pilot gain, first order lead, and a Pade approximation of the pure time delay. The aircraft model consisted of the longitudinal short period equations plus a wind gust term. The accuracy of the estimated pilot parameters was determined by numerically comparing the true and estimated parameters and by model matching, that is, by comparing the transient responses of the pilot aircraft model containing the estimated pilot parameters with the pilot-aircraft model containing the true values of the parameters.
