Abstract

Robotic flight simulators have emerged as a low-cost alternative to conventional flight simulators. Despite the enormous potential, few research works have been conducted regarding the representativeness of the movement of these simulators. Thus, the present work seeks to propose an optimization of the washout filter using the genetic algorithm to obtain the parameters capable of maximizing pilot's acceleration perception during the plane's takeoff. 3 configurations were proposed: solution 1 that does not impose displacement limits for channel B of the simulator, solution 2 with a limited displacement of 15 degrees for the channel B and solution 3 that considers the limit of 15 degrees and a different configuration of the cost function. It was found that the solution that maximizes pilot perception is the solution 1. Solutions 2 and 3 were similar, which indicates that it is the best configuration to be obtained with the current workspace limitation. The comparison of the 3 solutions also indicates that the trail could be further explored to increase the sensation of acceleration during takeoff. (AU)
