Dynamic analysis of Quadcopter with a novel controller

Quadcopter, also known as quadrotor, is an unmanned Ariel vehicle (UAV). This paper presents the dynamic analysis of a quadcopter for propulsion and flight control with system noise. The quadcopter is maneuvered by adjusting the angular velocities of the rotors which are controlled by the DC motors. In this paper, a novel controller is proposed that uses the properties of four-element viscoelastic material. To make the system robust some random noise is generated which is absorbed by the controller. The performance of the novel controller is compared with the conventional PID controller by making both the controller optimum. The robustness of the novel controller is compared with the PID controller by using the force-displacement hysteresis curve.
