Paper Abstract

The vast majority of gimbaled line-of-sight stabilization systems involve inertial angular rate sensors located on the gimbal assembly. These sensors are mounted to follow the line-of-sight as the gimbals move, thus allowing them to serve as direct feedback elements for the stabilization rate-control loops. For systems in which on-gimbal configurations are not possible, feedforward control configurations using strapdown inertial sensors are required. The gimbal control commands in these systems are calculated in real- time form the inertial sensor outputs and the transformation matrices between the sensor, gimbal, and line-of-sight reference frames. A testbed for the development and test of a feedforward line-of-sight stabilization systems is described. The system includes a three-axis, mirror-stabilized gimbal, a servoamplifier unit, and inertial measurement system, a digital controller, and a personal computer for software development.
