Building on a disturbance-observer-based Linear Quadratic Integral architecture with output-only autoregressive identification, the approach removes the need for explicit disturbance input measurements while preserving modeling accuracy. A lightweight neural module, implemented via a custom-designed Transformer model, is incorporated as a bounded residual compensator to refine control performance under non-stationary disturbances, and is further safeguarded by a gating mechanism to ensure stable fallback operation. Experiments on a production-grade optical terminal under representative multi-condition disturbances show consistently high identification correlation (up to 0.9997) and a substantial reduction in RMS jitter from 0.324918 to 0.04841\n                    <jats:italic>\u00b5<\/jats:italic>\n                    rad, with only 0.3% additional computational overhead, outperforming conventional control approaches.
