Fault tolerant control of flexible smart structures using robust decentralized fast output sampling feedback technique

Active vibration control is an important problem in structures. One of the ways to tackle this problem is to make the structure smart, adaptive and self-controlling. The objective of active vibration control is to reduce the vibration of a system by automatic modification of the system's structural response. This work features the modeling and design of a robust decentralized controller for a smart flexible system using fast output sampling feedback control technique when there is a failure of a system component (say, an actuator) to function. In this proposed control law, the control inputs to each actuator of the multimodel is a function of the output of that corresponding sensor only and the gain matrix has all off-diagonal terms zero. The designed robust controller provides satisfactory stabilization of the multimodel smart structure system.
