Abstract
Aircraft on-ground maneuvering is made manually by the pilot, the aircraft and the pilot close a loop forming one system that performs a trajectory, the analysis of the steering control system in closed-loop is crucial to prevent the aircraft from unstable events, which may cause damage to the plane, injured passengers, or even fatalities. This research goal is to propose a human pilot model to provide inputs for the simulation of nose wheel steering systems. The proposed model uses the heading error between the plane and a look-ahead reference as the main visual cue, that is feedback using a linear compensator. State feedback is considered assuming that the pilot can sense the yaw rate, a feedforward control is also included to contemplate the action made only based on the desired trajectory. For simulation purposes, a three degrees-of-freedom aircraft and steering system models are used in Matlab/Simulink. Finally, the grey-box identification is performed using the Parameter Estimator app in Simulink to adjust parameters for two behaviors. The pilot model performance is discussed, the results show the capability of the model to fit two different behaviors, moreover, the main parameters that should differ between behaviors are highlighted.
