An Emerging Controlling Process of Vibration with help of Fuzzy Logic Controller for a Cantilever Plate
نویسنده
چکیده
The purpose of this work is to control the vibration of the plate with the help of fuzzy logic controller. A finite element model of a two-dimensional cantilever plate instrumented with a piezoelectric patches sensor-actuator pair is derived. The contribution of piezoelectric sensor and actuator layers on the mass and stiffness of the plate is considered. Fuzzy logic optimal control scheme have been designed to study the control effectiveness. Tip displacement and tip velocity are taken as the inputs and the control forces are taken as the output to tune the fuzzy logic controller. Rule base of the fuzzy logic controller consists of nine rules. It is observed that fuzzy logic controller is found suitable and give effective control to suppress the first three modes of vibration of cantilever plate. With the help of MATLAB simulation the frequency and peak gain values are obtained.

The aim of this work is to optimise the vibration of the plate with the help of Adaptive neuro-fuzzy inference system (ANFIS) controller. The contribution of piezoelectric sensor and actuator layers on the mass and stiffness of the plate is considered. As the plate is square so we get total 64 squares. To validate the present code, frequency response has been compared with exact solution as wel...
