A method for the selection of sensor and actuator locations

A new and efficient technique for determining optimal locations of sensors and actuators of intelligent structures is presented. The optimization of s ensor and actuator locations is based on the Ist order singular value pertu rbations of observability and controllability. Using this method the optima l placements of sensors and actuators of the intelligent structurer can be selected. Two numerical examples are given to demonstrate the applications of the method. The impulse responses of structures due to different locatio ns of actuators with the same control law are analyzed in detail.
