| Abstract: | Here, optimal positioning of actuators on a flexible cantilevered plate, where PZT patches were used as actuators was investigated. A particle swarm optimizer was used as an optimization algorithm and energy-based controllable Gramian criteria were adopted as index functions. Simulation and test results indicated that the particle swarm optimizer is an effective algorithm for calculation of optimal positioning of actuators and especially fit for the case of multiple actuators;the control design based on optimal positioning of PZT actuators is effective. |
