T1 - Parameter setting of pilot behavioral dynamic model in aircraft control loop

AU - Zaitceva, Iu S.

N1 - Funding Information: Frequency and optimal methods, and handling qualities scale were used for quality assessment of the control system dynamic properties. Main Results. Numerical values of the pilot behavior model parameters are found on the example of a normal aerodynamic scheme, in which the elevator serves as an element of the tail unit. The numerical values estimation of the pilot model parameters is performed. The simulation results are given. Practical Relevance. The proposed approach to the pilot behavior simulating process during piloting simplifies, accelerates, and reduces the cost of an aircraft test program. Software simulation can be used at the test stage and before tests on flight simulators and will give the possibility to identify unsatisfactory handling characteristics of the aircraft and its control system and quickly correct them. Keywords handling qualities, human model, imitation, aircraft, optimization, frequency methods, oscillation index Acknowledgements This work was financially supported by the Government of the Russian Federation (Grant 08-08).

N2 - Subject of Research. The paper considers a flight control system for the longitudinal movement of an aircraft with a human-pilot in a closed loop. Computer simulation setting of the selected pilot behavioral model is carried out in the compensatory tracking mode. The parameters correspond to the optimal behavior of the pilot providing the best aircraft dynamic characteristics. Method. Padé approximation was used when creating a computer program for calculations.
