摘要

The placement optimization of piezoelectric actuators and active vibration control of a membrane structure are studied in this paper.The classical linear quadratic regulator controllers are designed to suppress the unwanted vibration.Simulation results indicate that the optimal locations of piezoelectric actuators are affected deeply by the additional mass and stiffness of actuators,the computational efficiency of particle swarm optimizer is higher than that of genetic algorithm for this particular problem,and the control performance of optimally placed actuators is better than that of non-optimally placed actuators.
