In this paper a method of finding optimal positions for piezoelectric actuators and sensors ondifferent structures is presented. The genetic algorithm and multi-objective genetic algorithm are selected foroptimization and H∞ norm is defined as a cost function for the optimization process. To optimize theplacement concerning the selected modes simultaneously, the multi-objective genetic algorithm is used. Theoptimization is investigated for two different structures: a cantilever beam and a simply supported plate.
Vibrating structures are controlled in a closed loop with feedback gains, which are obtained using optimalLQ control strategy. Finally, output of a structure with optimized placement is compared with the output ofthe structure with an arbitrary, non-optimal placement of piezoelectric patches.
