Finite element analysis and active vibration control of a cantilever beam

Abstract

Summary form only given. Finite element modeling of a cantilever beam and active vibration control are implemented within the MATLAB environment. Using classical root locus design techniques, a lead-lag compensator is designed to stabilize the beam and to eliminate the effect of a step disturbance. This utilization of the finite element method and control system theory in a common software environment has valuable applications in active vibration control of more complex mechanical systems such as space structures and lasers.
