Applying Qian Xuesen’s Engineering Cybernetics to Suppress Hallucinations in Large Language Models

The paper formulates LLM hallucination as systemic noise, builds a forward‑feedback‑adaptive control loop using Prompt engineering, Retrieval‑Augmented Generation and a hallucination detector, proves global asymptotic stability via Lyapunov theory, designs an LQR optimal controller and an MRAC adaptive scheme, and demonstrates up to 5 dB SNR improvement and sub‑5% hallucination rates on standard benchmarks.
