Abstract—In this issue we try to control the free vibration response of aluminum or iron or other substance cantilever beam with 2 Piezoelectric patches (Actuator & Sensor) attached on the top and bottom surfaces of the beam. On the other hand we also want to reduce the amplitude of the vibrating beam in a controlled manner. In order to achieve these tasks we model the smart structure by using the Euler-Bernoulli beam theory. The concept of finite element (FE) theory is used in this issue. In this method the beam is divided into several equal segments (for example in this paper the beam is divided into 4 equal part), which is also equal to the length of the actuator and sensor or not equal to them and Piezoelectric patches are attached to the second element. In this method the beam is divided into several equal segments (for example in this paper the beam is divided into 4 equal part), which is also equal to the length of the actuator and sensor or not equal to them and Piezoelectric patches are attached to the second element.
