Abstract: A parameter identification method of pilot structural model is presented, which is based on the real time simulation experiment of a pilot aircraft system. The pilot description function is measured from the experiment results of the pilot-aircraft simulation. Then parameters of the pilot structural model are identified in accordance to the least squares estimator, in which a sensitivity formula of the pilot model parameters is developed in order to improve the parameter algorithm. An example is implemented on condition that the controlled objector model is the longitudinal equivalent model of aircraft for a compensatory tracking task. The example and results indicate that the method is effective for the parameter identification of the pilot structural model.
