センサ・アクチュエータの最適配置に基づくCFRP積層板の振動計測・振動制御

The present paper treats a technique of vibration measurement and control based on the optimal placement of sensors and actuators. In the second report of this paper, the experimental verification of vibration measurement and control for CFRP laminated plates is carried out using a modal sensor and a modal actuator. The modal sensor is constructed using accelerometers, based on the criterion of minimum observation spillover, while the modal actuator is constructed using PZT piezoelectric materials, based on the criterion of minimum control spillover. Some experimental results demonstrate that the optimal placement of sensors and actuators is very important to stabilize a control system for a limited number of sensors/actuators, and the vibration of laminated plates can be suppressed effectively by state feedback control for each mode using the modal sensor and actuator.
