چکیده:

Optimal placement of actuators and sensors is an important problem in control of structures that is often selected without any systematic method. Appropriate placement strongly influences on the performance of control system. This study is presented in two parts In this paper as the first part, Actuators Placement is presented. In this way, a general method is suggested based on a proposed constrained genetic algorithm to determine the optimal placement of actuators in structures. The optimal placement scheme is general for passive, active and semi-active controls. It can handle linear and nonlinear constraints and it does not depend on strategy of control and dynamics of control system such as nonlinearities. The efficiency of proposed method is evaluated on the 20-story benchmark building. The optimal scheme is applied on the sample active LQG control system to place 25 and 5 actuators. The results show that the proposed method could find the optimal placement of actuators and improve the performance of control system. Generally, the proposed method is an approach to achieve the best utilization of available resources.
