PARAMETER IDENTIFICATION OF FLEXIBLE PLATE BASED ON THE ACCELERATION OUTPUT

This paper studies the parameter identification using a flexible plate as research object. An eigensystem realization algorithm (ERA) based on the output of acceleration sensors is investigated and the optimal positions of sensors on the plate are studied using the particle swarm optimization (PSO). Simulation results indicate that the PSO may effectively determine the optimal positions of sensors on the plate, and the plate parameter may be identified accurately using the ERA.
