Quantile-Based Command-Reserve MPC for Current-Command Gimbal Pointing Control

This paper studies line-of-sight pointing control for a two-axis current-command gimbal under mismatched mechanical disturbances. It proposes a quantile disturbance predictor and a tube-inspired model predictive controller that reserves command headroom according to prediction uncertainty. On a two-axis embedded platform, the proposed configuration achieved a 2D pointing RMS error of 3.94 ± 0.10 mrad, with no command-saturation samples within the evaluation window; solve times and cycle overrun records are reported separately for a 100 Hz nominal implementation.
