An adaptive modal positive position feedback (AMPPF) method is presented for controlling the vibration and shape of flexible structures. The proposed strategy combines the attractive attributes of the independent modal space control (IMSC) of Meirovitch and the positive position feedback (PPF) of Go
The vibrations of flexible structures are controlled by an optimal modal positive position feedback (OMPPF) algorithm whose control forces are generated by only using modal position signals to provide damping action to undamped structural modes. The suboptimal parameters of the OMPPF controller are
