Nagiredla, S.Joladarashi, S.Kumar, H.2026-02-062024Lecture Notes in Mechanical Engineering, 2024, Vol., , p. 175-18121954356https://doi.org/10.1007/978-981-97-0900-7_14https://idr.nitk.ac.in/handle/123456789/29040Vibration control is a rapidly developing field and research is being carried out on different methods to attenuate the harmful vibration levels. Composite materials carry the advantage of providing enhanced material properties compared to that of conventional materials. This work mainly focuses on conducting the transient analysis on hybrid composite sandwich beams with viscoelastic core and to implement the linear quadratic regulator (LQR) and Proportional, Integrate and derivative (PID) controllers. The transient response of the hybrid composite sandwich beam with the viscoelastic core is presented and the active vibration control study was implemented on the sandwich beam’s transfer function which is obtained by using system identification technique. It was found that there is a substantial change in settling time as well as vibrational amplitude. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.LQR controllerPID controllerSandwich beamTransfer function
