Design and simulation of LQR controller based on fast steering mirror used in compound-axis system

In this paper, we introduced the principle of using fast steering mirror (FSM) in compound-axis systems. Based on the modeling of a fast steering mirror, the linear quadratic regulator (LQR) controller design process is demonstrated. Several simulation experiments were done using the LQR controller that was designed, and the results were compared with two commonly used classical control theory controllers. The result of comparison and system analysis shows the effectiveness of the LQR algorithm.
