Man's extensive need for clean energy sources is one of the basic issues in human life, and he has always looked for an endless source of power in his imagination that can be used at any time and place and has no impact on the environment. Piezoelectricity They are one of the sources of endless electrical energy production. In recent years, due to the possibility of using piezoelectric materials in various fields such as shape control, vibration and sound depreciation, and structural defect detection, these materials have attracted the attention of many researchers and scientists. In this research, induced oscillations caused by vortex shedding around the cylinder and piezoelectric blade are controlled. In this way, the desired model is considered for two modes with controller and without controller. In addition, for the given problem, three different values ​​for the activation criterion of the control system in the state with the presence of the controller are investigated. The displacement parameter of the tip of the blade is considered as the criterion for the activation of the controller. In other words, if the displacement of the tip of the blade exceeds a certain value, the control system enters the circuit. The results of the comparison show that the use of the controller can reduce the fluctuations of both components of the problem, i.e. both the cylinder and the blade. Also, the comparison of the results obtained from three different values ​​for the displacement of the tip of the blade shows that the control performed on the problem has a better efficiency in smaller displacements because in smaller displacements, a shorter time is spent until the controller is applied. Therefore, in these cases, the controller enters the circuit faster and prevents blade oscillations in a shorter time, which results in better system control.
