Summary:This paper presents the control of lateral flight dynamics of F-16 aircraft using simple control techniques. The control of Lateral flight dynamics is an important characteristic for Automatic Flight Control System (AFCS) design. We used Linear Feedback and Linear Quadratic Regulator (LQR) techniques to control the lateral flight dynamics of aircraft. A linearized aircraft model is used because the control techniques that we used can be applied on linear system. Pole placement technique is used to place the poles at a desire location that stabilized the response of controller and find the value of feedback gain matrix K for Linear Feedback Controller. In LQR technique to find the value of feedback gain matrix K, first we choose an appropriate values of Q and R matrices, where Q and R are weighing matrix. According to the initialization of state space vector, the transient response of lateral dynamics (Slide Slip Angle, Roll rate, Yaw rate and Roll angle) are investigated and the performance of both controllers are compared.
