Optimal flight control on the hawker 800 XP business aircraft

Even with the advancement of technology in the aerospace industry, we increasingly need to study the flight control system problems in real time to ensure greater efficiency, and in the presence of uncertainties. In this research we will conduct a study of modeling and control system design for a business aircraft. A nonlinear model of the Hawker 800 XP aircraft was designed, and then linearized by small disturbance method. A Linear Quadratic Regulator (LQR) technology was used to achieve desirable dynamic characteristics; a robustness analysis of the optimal gain was performed to choose a robust gain which can resist to uncertainties and trim the aircraft while maintaining its stability and its acceptable performance.
