| Abstract: | A new method for determining optimal locations of the distributed piezoelectric actuators of intelligent structures was presented. The main idea is that element sensitivities of singular values are used to identify optimal locations of actuators. In order to determine optimal locations of piezoelectric actuators, following steps can be done: firstly, the measurement of modal controllability of intelligent structures is discussed; secondly, formulas of element sensitivities of singular values of controllable matrices with distinct and repeated singular values are developed; lastly, the optimal criterion of locations of actuators is presented according to the actuator element sensitivities of the singular value of controllable matrice. A numerical example was given to illustrate the validation and application of the presented method. |
