Adaptive Predefined-Time Attitude Control for Spacecraft presents the latest advancements in spacecraft control dynamics, with a particular focus on time-bound strategies that guarantee rapid and smooth system stabilization under realistic mission constraints. Rooted in the expertise of scholars with extensive experience in nonlinear and adaptive control, the book establishes a solid theoretical foundation in finite-time and predefined-time formulations before transitioning to sophisticated techniques such as fuzzy logic, dynamic surface control, neural networks, and event-triggered design. Subsequent chapters broaden the scope to encompass multi-spacecraft coordination and time-triggered adaptation, reflecting the growing trend toward autonomy and intelligent systems in modern aerospace applications. Readers are guided through a cohesive suite of state-of-the-art methodologies, along with insights into emerging trends and future frontiers, all engineered to optimize reliability, efficiency, and fault tolerance. Graduate students, early-career researchers, and experienced engineers in both academia and industry will find this volume a comprehensive and indispensable reference for the design and deployment of intelligent attitude control systems in modern flight and satellite missions.
