Fast steering mirrors (FSMs) have been used for decades to improve the performance of electro-optical imaging systems, such as airborne systems and space-based optical surveillance systems. With advantage increasing accuracy image motion compensation efficiency scanning imaging, backscanning step-and-stare has become main approach realizing wide-area According operating mode profile FSM in system, a combined optimized (COP) is designed avoid abrupt changes velocity acceleration FSM. The...
This article proposes a comprehensive approach to achieve high-precision modeling, high bandwidth, and robust control for the voice coil actuator fast steering mirror (VCA-FSM). includes Hankel matrix identification method, <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$H_{\infty }$</tex-math></inline-formula> sensitivity control, disturbance observer (DOB), zero phase error tracking (ZPETC) algorithms....
The mechanical alignment error of the voice coil motor and its internal flexible support structure can influence modeling accuracy limit improvement control system's tracking bandwidth. To address above-mentioned issues: firstly, nominal model actuator-fast steering mirror (VCA-FSM) is obtained by frequency response identification method, quality evaluated gap metrics; secondly, an <tex xmlns:mml="http://www.w3.org/1998/Math/MathML"...
