This book deals with flight control design for elastic Airplane based on the optimization of Root Locus migration. The determination of the number and location of control system components such as sensors can be critical to the robust functioning of active control systems, especially when the system of interest is a large high-speed aeroelastic vehicle. The position of the sensors affects both system stability and the performance of the closed-loop system. a new approach for sensor placement in the integrated rigid and vibrational control of flexible aircraft structures is developed....
