Research On Intelligent Control Of Flight Attitude For The Tricopter

Comparing with the fixed-wing UAV, the UAV with rotors have the advantage of taking less energy, having stable structure, less cost. They become focus areas either in China or in other countries. Among them, the tricoper has the advantage of simpler structure, less energy, less cost than other kinds of UAV. So it has good prospect and practical value.In this paper, On the based of UAV’s situations in China and other countries. We have the study on the tripcoter. It including the torque analysis for the tricopter’s system, establishment of mathematical model, then it used LQG and fuzzy PID control method to design the tricopter’s flight attitude controller. In order to examine the effect of intelligent control, Simulated the effect of these controllers using MATLAB software and compared the simulation’s results. It showed that using fuzzy PID control method to design the controller has the quicker response and better efficient than using LQG controller.
