DEVELOPMENT OF DYNAMIC MODEL FOR VIBRATION CONTROL OF FLEXIBLE BEAM

The present study aims at developing a new dynamic model for vibration control of a composite carbon cantilever beam. The finite element method (FEM) is used to derive the introduced model. Modal analysis is performed on the cantilever beam using ANSYS software package and results were compared with similar published work using ABAQUS software package to validate the results obtained from ANSYS. The theory behind the extraction of flexible beam model from the finite element model is introduced. The eigenvalues and eigenvectors resulting from this analysis are integrated into MATLAB, which is used to derive the state space model of the system. Through MATLAB/ SIMULINK tools a PID controller was designed and controlled system performance under different system inputs is studied to test the efficiency of the controller. The results show similar responses and similar error percentage signals to various step input angles. In addition, the system shows a good performance to sine wave input signal despite the presence of a minor lag.
