Abstract

Large structures used in space applications are made flexible to reduce the high cost of lifting mass to orbit. Since these structures are highly vulnerable to dynamic excitations, the incorporation of active control systems, coupled with the consideration of multiple objectives in their design, becomes important. In addition, the selection of number and location of actuators/sensors plays an important role in the performance of the active control system. This wok addresses both the aspects of actuator/sensor location and multiobjective optimization in the design of control augmented structures. The actuator/sensor location selection problem is formulated as a zero-one problem and a generalized penalty function method and a genetic algorithmic approach are studied for the solution of the problem. The multiobjective problem is studied using a modified game theory technique. The effectiveness of the methods is illustrated through simple actively controlled structural examples.
