  abstract =     "the parameters of vibration control system of smart
                 beams, including the placement and size of
                 piezoelectric sensors and actuators (S/As) bonded on
                 smart beams and the feedback control gains of the
                 control system, have been simultaneously optimised for
                 vibration suppression of beam structures. Since the
                 sizes of the S/As are selected from a prescribed patch
                 pool provided by the manufactures, the size design
                 variable is then discrete, but the locations and
                 feedback gains are continuous. Thus, the resulting
                 optimization problem has discrete-continuous design
                 variables which is difficult for the conventional
                 optimisation methods to solve. An integer-real-encoded
                 genetic algorithm has thus been developed to search for
                 the optimal placement and size of the piezoelectric
                 patches as well as the optimal feedback control gains.
                 The criterion based on the maximisation of energy
                 dissipation was adopted for the optimisation of the
                 control system. The optimal distributions of the
                 piezoelectric patches based on specific controlled
                 vibration modes have also been addressed. The results
                 showed that the control effect could be significantly
                 enhanced with appropriate distribution of piezoelectric
                 patches and selection of feedback control gains, and
                 meaningful observations have been obtained for
                 practical design.",
