Article Preview

There are some problems in the control for a large flexible spacecraft on orbit such as the coupling, destabilization, and performance of the control system. To solve the problems, an active tuned mass damper (ATMD) is developed utilizing the piezoelectricity smart material, and an optimal output feedback control strategy is proposed based on the positive position feedback (PPF) method. The numerical simulations show that the developed ATMD/PPF method can suppress the flexible structural vibration induced by disturbances effectively. Using the method, the stability of the control system can be ensured and a good performance can be maintained even in case that the ATMD is in failure.
