Abstract
This article explores optimal vibration suppression of a cantilever beam using collocated piezoelectric sensor/actuator pairs. A rectangular aluminium plate modelled in cantilever shape with one pair of piezoelectric patches as sensor and actuator has been used to investigate the effective vibration control. A state-space model for simulating time response of modes of a beam with piezoelectric sensor/actuator pairs has been developed. Total integrated energy stored in the system was minimized by varying the position of piezoelectric patches of constant length while kee** feedback gains constant. COMSOL Multiphysics 5.4 version software has been used to derive the finite element model of the plate. According to this model, the locations of the ideal sensor are found and a definite beam is shaped. An appropriate simulation control procedure has been investigated through MATLAB software by which the gain of the controller has been optimized to achieve efficient active vibration suppression with a minimum control input.
