MODELING AND ATTITUDE CONTROL OF A QUADCOPTER USING LINEAR QUADRATIC REGULATOR
A quadcopter is a helicopter with four rotors. Its unique design allows a more stable platform, making quadcopters ideal for tasks such as surveillance and aerial photography. And it is also getting very popular in unmanned aerial vehicle UAV research in recent years. In this paper we are presenting the mathematical model for possible movements of the quadcopter and compute the linear quadratic regulator (LQR) to achieve the stability of the attitude i.e. Euler’s angles of the quadcopter.
