Abstract

In this paper, optimal position of actuators on flexible cantilever plate is investigated, where PZT patches are used as actuators, particle swarm optimizer is used as optimization algorithm and energy-based controllable Gramian criteria is adopted as index function. Simulation and experimental results indicate that particle swarm optimizer is an effective algorithm for the calculation of optimal positions of actuators and is especially fit for the case of multiple actuators; the control design based on the optimal position of PZT actuator can obtain good control effectiveness.

Key words
