【Abstract】 An active control strategy is discussed which utilizes a Modal Filter(MF) and optimal control theory to implement Independent Modal Space Control(IMSC) of intelligent truss space structures.The control scheme makes IMSC no longer be confined to the control of simple and low degree of frieedom systems.An experimental example through numerical simulations demonstrates that the strategy solves perfectly the problem of state decoupling in classical IMSC.The results show that the active control utilizing MF based IMSC for intelligent space truss structures is feasible and effective.更多还原
