摘要：
The active control of structural vibration depends not only on the design of the control law in the controller, but also on the position of the actuators in the structure. The responses of the structural vibration in the low frequency range can be suppressed due to the proper arrangement of the actuators. In this paper, the cylindrical shell was taken as the object of study based on the controllability and observability criterion of the discrete system. And then, a design of the optimal position of the actuator based on the particle swarm optimization algorithm was proposed and verified by the active control experiments. The experimental results show that the particle swarm algorithm can be applied to the optimal design of the actuator position in the cylindrical shell, and the good control effect can be achieved in the vibration control experiment. © 2019, Editorial Board of Journal of Ship Mechanics.
