This paper investigates the feasibility of using active force control (AFC) method for the problem of active vibration control (AVC) of a flexible thin plate structure through simulation. The plate system was first modeled and simulated using Finite Difference (FD) method. Then, the validity of the obtained computational model was investigated through comparative studies between the plate natural frequencies predicted by the model and the exact values of resonance modes found in literature. The AFC algorithm was then embedded within the FD simulation platform to study the performance of the control scheme. An appropriate value of the mass gain in the AFC algorithm was estimated to be 14 kg through crude approximation technique which was later shown to be close to the real mass of the plate system. Different types of disturbances were applied to excite the plate system at different excitation points so that the robustness of the proposed control algorithm can be evaluated in terms of its performance in reducing the vibration at observation point. Results of the study clearly demonstrated the effectiveness of the proposed control strategy to attenuate the unwanted vibrations of the flexible thin plate system.
