Abstract
The mathematical model of a flexible beam covered with shape memory alloy (SMA) layers is presented. The SMA layers are used as actuators that are capable of changing the elastic modulus and recovery stress, thus changing the natural frequency of and adjusting the excitation to the vibrating beam. A linear control law is determined based on optimal regulator theory. The control results are discussed.
