Vibrations caused by thermal control system severely affect the Chinese Large Solar Telescope (CLST). The linear quadratic Gaussian (LQG) controller has been tested on the solar adaptive optics (SAO) system equipped in the CLST to mitigate these vibrations. An automatic identification method based on the particle swarm optimization (PSO) algorithm is used to compute the parameters of the LQG controller and verified on the CLST. Experimental results are presented in this paper, which show a significant reduction in vibrations in both X and Y axes, illustrating the superior performance of the LQG controller compared to the conventional proportional-integral (PI) controller.
