Aircraft Automatic Control Systems

This chapter provides a comprehensive overview of the current state of automatic control systems employed in modern commercial and military aircraft. It delves into the intricate dynamics and mathematical modeling of aircraft, encompassing aspects such as aerodynamics, structural dynamics, and environmental disturbances. The chapter extensively covers various control systems, including stability augmentation systems (SAS), control augmentation systems (CAS), and autopilots, essential for ensuring aircraft stability, maneuverability, and enhanced flight characteristics. Particular emphasis is placed on the guidance and navigation systems that enable autonomous flight operations, trajectory tracking, and precise landing capabilities. The chapter also explores emerging trends and future directions in aircraft control, such as fault-tolerant control strastegies, gust alleviation techniques, and advancements in auto-landing systems, addressing the challenges and opportunities in this rapidly evolving field.
