Abstract

Electrical noise in gimbal control loops can directly impact gimbal drift and Line-of-Sight motion in electro-optic systems. When electrical noise saturates the control loop, the loop operates non-linearly, and changes the loop's ability to reject disturbances. Should the requirement for this loop noise stay below the saturation point for adequate gimbal control? This paper provides an avenue to study Line-of-Sight stabilization performance in the presence of saturating loop noise. The rate feedback device is a two-axis piezoelectric gyro that senses gimbal structural flexure and linear vibrations.
