117951 - Summarized Lqg/ltr Controller for a Subscale Aircraft Arrestment System With Nonlinear Dynamics and Minimal Sensors 

The design of a digital controller for a motor driven aircraft subscale arrestment system is a complex and challenging task. This paper proposes a method that can address the control challenges posed by the limited sensors and nonlinear dynamics of the system. The focus of the paper is on the arrest phase controller that brings the aircraft to a stop without steering it off course. The proposed method is based on an adaptive linear quadratic Gaussian/loop transfer recovery (LQG/LTR) control algorithm. This algorithm is developed using a MIMO (multiple input multiple output) design technique, which is important for high performance since the system behaviors are coupled. Ignoring this coupling can result in suboptimal performance. The algorithm developed in this paper is able to generate good tracking performance for the aircraft position and velocity, and successfully arrest the aircraft within the required bounds. The simulation and experimental results using a subscale arrestment system have demonstrated the effectiveness of the proposed algorithm. The proposed method has the potential to improve the safety and efficiency of aircraft carrier operations. By providing a robust and reliable control algorithm, it can reduce the risk of accidents during arrestment and minimize the wear and tear on the aircraft and the arrestment system. The proposed method can also be applied to other systems with limited sensors and nonlinear dynamics, making it a valuable contribution to the field of control engineering
