Optimal placement of piezoelectric actuators in intelligent structures using genetic algorithms

Many piezo actuators can be used without increasing costs and weights of corresponding control system with common control command. Piezo actuator configurations which maximizes degrees of controllability are obtained using genetic algorithms, general optimizers. Optimal placement of piezo actuators is determined for a cantilevered plate, and it is observed that actuator pattern is closely related to the phase of modal control force of each actuator.
