Finite Element and Experimental Investigation and Control of Vibration of Piezoelectric Smart Beam
Vibration of a smart beam is being controlled. This smart beam setup is comprised of actuators and sensors placed at the root of a simply supported beam. Vibrations can be caused by various sources including human activity and nearby motorized equipment. In this case, disturbance is produced by using a Piezoelectric actuators. The piezoelectric sensors are used to detect the vibration. Simultaneously, feedback controller sends correction information to the actuator that minimizes the vibration. To optimize results, controllers were designed using LQR control theory. This theory generally results in high-order controllers. Additionally, optimal control theory is being used to directly optimize low-order controllers.
