Control Algorithm and Experimental Analysis for Optical Beam Stabilization System

In this paper, a optical beam stabilization system based on smart material actuators, a corresponding computer control system and experiments using adaptive filter LMS algorithm are proposed. The structure, the principle and the control strategy of the optical beam stabilization system are introduced. The experimental results and analysis are proposed. The control experiment result of the optical beam stabilization system is 20~30 dB. It proves the system principle and the correctness of the control strategy.
