Design of Vectored Sum Defuzzification Based Fuzzy Logic Systems for Position Control of a Quad-Copter

摘要

Studies on the quad-copter system which is one of various drones have widely been progressed. Quad-copter system is flying to up and down and left and right using four propellers. It is also a typical example of a nonlinear system. In this paper, we propose the design of two fuzzy logiccontrol systems for the position control of a quad-copter. We first introduce a new defuzzification method called vectored sum scheme. And then we design two fuzzy logic control systems using the vectored sum defuzzification scheme for the position control of the quad-copter. One is the conventionaltwo-input fuzzy logic control system and the other is a simple-structured system using only one input variable. In order to check the feasibility of the proposed systems we present some simulation examples.
