Abstract


The main objective of the present work is to investigate the design aspect of optimal controller for the pitch control of an aircraft. In this paper Linear Quadratic Regulator (LQR) for optimal stability analysis of closed loop attitude control system of an aircraft is presented. The result of proposed controller is compared with classical proportional integral derivative (PID) controller. It is observed that the optimal control technique outperforms the PID controller.
