  abstract =     "In this paper, modelling of the vibration of
                 cylindrical shell components of space structures
                 incorporating piezoelectric sensor/actuators (S/As) for
                 optimal vibration control is proposed and formulated.
                 The parameters of the control system, which include the
                 placement and sizing of the piezoelectric S/As and the
                 feedback control gains, were considered as design
                 variables and optimised simultaneously. The effect of
                 the amount of piezoelectric patches was investigated as
                 well. The criterion based on the maximisation of energy
                 dissipation was employed for the optimization of the
                 control system. A modified real-encoded genetic
                 algorithm (GA) dealing with various constraints has
                 been developed and applied to search for the optimal
                 placement and size of the piezoelectric patches as well
                 as the optimal feedback control gains. The results of
                 three numerical examples, which include a simply
                 supported plate, a simply supported cylindrical shell,
                 and a clamped-simply supported plate, demonstrated
                 significant vibration suppression based on the optimal
                 design of the control system. It was also found that
                 for specific controlled vibration modes, the optimal
                 distribution of the piezoelectric S/As should be
                 located at the areas separated by the nodal lines to
                 achieve the optimal control effect. This finding would
                 be useful for the practical design of smart
                 structures.",
