Robust H∞ Missile Autopilot Design

I need a complete H∞-based control solution that lets my missile autopilot remain stable and reliable across a wide envelope of flight conditions and model uncertainties. The work starts from the nonlinear or linearised dynamics I will supply; from there, I expect you to derive or refine the state-space model, set up the weighted mixed-sensitivity formulation, and tune the H∞ controller so it meets industry-standard robustness and performance margins.

Please implement and simulate everything in MATLAB/Simulink, documenting the exact toolbox functions and scripts you use so I can reproduce every step. When the design is closed, deliver:

• Clean, well-commented MATLAB/Simulink files for the plant model, weighting functions, synthesis, and time-/frequency-domain analyses
• A concise technical note that explains design choices, achieved γ value, gain/phase margins, and key plots (step, Bode, Nichols, Monte-Carlo uncertainty sweeps)

I will run an independent Monte-Carlo batch on my end; acceptance hinges on the controller keeping the closed-loop system stable and within my envelope limits across that sweep.
