APPLICATION OF HYBRID GENETIC ALGORITHMS FOR OPTIMUM ARRANGEMENT OF ACTUATORS TO INITIALLY STRESSED BEAM STRING STRUCTURES

Abstract

The method to determine the members to be initially stressed on beam string structures has to be discussed to effectively reduce the control forces or energy. This study treats the problem of optimal arrangement of actua- tors on beam string structures by using hybrid genetic algorithms combined with heuristic algorithms. Genetic algorithm based on the principle of genetics and natural selection is efficient for such problems, since it is possible to obtain the global optimum solution without using function gradients. The performance of the hybrid algo- rithms for solving the optimum arrangement problems is illustrated by the results of numerical simulations.
