Paper Title
Performance Of Fuzzy Logic Based Modal Controller In Active Vibration Control Of A Beam

In this paper fuzzy logic based modal control of cantilevered beam is done. Beam is instrumented with piezoelectric patches near the root of the beam. One piezoelectric patch act as sensor and another act as actuator. Fuzzy rule base is designed using 3 rules. Modal velocity of beam is taken as input to the fuzzy controller and modal force to be applied on the beam is taken as output from the fuzzy controller. Fuzzy logic is used to simultaneously control first two modes using principle of Modified Independent Modal Space control. Finite element model of beam is done using Hamilton’s principle and Newmark beta method is used to solve second order differential equations. Keywords— Active vibration control, Fuzzy logic, IMSC.
