This book provides a comprehensive analysis of fault tolerant control (FTC) for more-electric civil aircraft. FTC is a crucial approach to enhance the reliability and safety of aircraft in the event of actuator, sensor, or structural failures. Engineers and scientists from diverse disciplines, including aeronautics, electrical, mechanical, and control engineering, have been drawn to research on FTC. This book analyzes the impact of faults on performance degradation in dissimilar redundant actuation systems of civil aircraft and presents the FTC methods to ensure reliable actuation and efficient control. Additionally, this book addresses surface damage issues, such as the loss of elevator, horizontal stabilizer, and rudder, by providing representative FTC methods. The book’s major highlight is its comprehensive and systematic approach to FTC design, making it an ideal resource for readers interested in learning about FTC design for civil aircraft. The book benefits researchers, engineers, and graduate students in the fields of FTC, adaptive control, flight control, etc.
