Metodologia de otimização para sistemas de comandos de voo em aeronaves de asas rotativa

Abstract

This work presents the development of a methodology for optimizing control parame- ters for rotary-wing aircraft. This methodology encompasses reading the aircraft data, determining the control architecture used, selecting the design variables, performing an optimization stage using the Sequential Quadratic Programming algorithm and another using the Particle Swarm Optimization algorithm, as well as a comparison between the optimized and the original aircraft. The objective of this methodology is to select the best control loop parameters that meet the flight quality requirements established by certification standards, in order to avoid rework and assist the designer in building an optimal control architecture. The results showed that, after optimization, the optimal aircraft had both its dynamic modes stabilized and its flight qualities significantly improved under all flight conditions considered, thus demonstrating the effectiveness of the optimization methodology employed.
