Fuzzy logic controller design for an Unmanned Aerial Vehicle

摘要

Aircraft design consists of many steps such as an aerodynamic design, structural analysis and flight control design etc. And flight control is one of the crucial design aspects in modern aircrafts. Modern day aircrafts heavily rely on automatic control system for most of the functions and there is always a persistence demand for efficient controllers. There are many control techniques and methods developed in the field of control Engineering. But there are only a few numbers of controllers that we can be relied on. However the conventional techniques only work efficiently for liner system but in the real world, the air craft dynamics are highly non liner and thus there is the need for a controller which works perfectly for non-liner trajectories. Fuzzy logic controller is a non-liner control technique which uses a linguistic approach for controlling, based on some set of membership functions and rules. This research attempts to design a flight controller using a fuzzy logic system.
