Beam steering element feed forward command aiding architecture
First Claim
1. A feed forward command aiding architecture method, the method comprising:
- generating angle and rate commands from a received inertial data input;
feeding the angle command into a proper order position loop producing an intermediate result;
differentiating an angle feedback producing a rate loop feedback;
feeding the intermediate result, rate command, and rate loop feedback into a proper order rate loop producing a torque command, the proper order rate loop nested inside of the proper order position loop; and
moving a two-axis beam steering element of an electro-optic sensor based on the torque command to deflect a line of sight of the electro-optic sensor by an angle approximating the received inertial angular input.

Abstract
A feed forward command aiding architecture with corresponding method, system, and computer product are provided. The feed forward command aiding architecture includes generating angle and rate commands from a received inertial data input. The angle command is feed into a proper order position loop producing an intermediate result. An angle feedback is differentiated producing a rate loop feedback. The intermediate result, rate command, and rate loop feedback are then feed into a proper order rate loop producing a torque command. The proper order rate loop is nested inside of the proper order position loop. The torque command being generated moves a beam steering element of an electro-optic sensor to deflect a line of sight of the electro-optic sensor by an angle approximating the received inertial angular input.
