Modelling and Control System Design for UAV Tri-Rotor

The drones are devices of high technology that work thanks to the rotors that allow them to remain and to be propelled in the air. Their movements are controlled by adjusting the propulsion of each propeller and this is done with a device called a flight controller. The paper presents two control system for a UAV-Tricopter. The control techniques proposed are: proportional derivative and integral controller (PID) and Linear Quadratic Gaussian Controller (LQG). These techniques force the tricopter to follow with precision the given trajectory. The simulink toolbox was used to make the designs of each controller and then see the behavior of each control strategy.
