ROBUST CONTROL OF CHAOTIC VIBRATION OF COMPOSITE PLATE IN THE PRESENCE OF NOISE USING SLIDING MODE METHOD

Abstract

Robust control of chaotic vibration in composite plate in the presence of noise using sliding mode control methodology is considered in this paper. The composite plate system has a combination of linear, quadratic and cubic stiffness terms. Robustness of the controller is analyzed with reference to the parametric variations of the system and external disturbances due to noise and compared with Pyragas control method. The composite plate considered is a six-layered rectangular antisymmetric cross-ply plate with immovable edges. The plate is assumed to be viscously damped and harmonically excited.
