- This paper studies the optimal design of piezoelectric actuators for suppressing
noise transmission of a vibration plate. The optimal placement of the actuators to reduce the
global noise levels is still a significant design problem, especially placement limited to
discrete locations. With the increase of the alternative locations and number of actuators, a
large number of placement possibilities exist. These multi-dimensional nonlinear problems
are very difficult for traditional optimization methods. In this paper, genetic algorithms have
introduced to solve the problem of optimal discrete placement of piezoelectric patches. In
order to improve the diversity of the population, a new selection factor is presented that is
based on immune diversity, which is dependent on the string denseness and its function value.
The survivor probability of the string with higher denseness will be reduced. Several cases
for a simple supported plate under different load conditions show that the improved
algorithms are efficient.
