Controlo de quadcopter

Authors: Martins, Rui Miguel Freitas;

Controlo de quadcopter

Abstract

O controlo de voo dos quadcopters tem grande interesse devido ao aumento de número de aplicações que recorrem a este tipo de aeronaves. As vantagens que o recurso a 4 conjuntos de motor e hélice como meio de propulsão apresenta em relação a outro tipo de drones, são a capacidade de se manter imóvel no ar e a capacidade de descolar e aterrar na vertical. Ao mesmo tempo que um quadcopter tem estas vantagens, o sistema não linear tem 6 graus de liberdade, com apenas 4 atuadores o que coloca assim desafios no controlo de orientação e posição. O objetivo principal deste projeto consistiu em estudar a dinâmica do quadcopter, e aplicar diversas técnicas de controlo que permitiram controlar a orientação e altura do drone, tanto em simulação como a nível experimental. As técnicas de controlo foram a técnica PID, a técnica Fuzzy-PID e a técnica de backstepping. Das três técnicas utilizadas a que teve o desempenho mais robusto foi a técnica de backstepping e a que exigiu menos processamento computacional foi a técnica PID. A nível experimental efetuou-se a montagem do quadcopter e implementou-se um controlador de voo que recorreu a controladores PID para controlar a orientação, com resultados que se comportaram como na simulação.
