Design example: Elevator augmentation

• Solution Insight: To verify your solution, check if the short period natural frequency ($\omega_n_sp$) is approximately $\sqrt-M_\alpha Z_\alpha$ and check if the phugoid frequency ($\omega_n_p$) is approximately $\sqrt-g Z_u / u_0$. If these approximations don't match your full matrix solution by an order of magnitude, you likely made a sign error in $Z_u$ or $M_\alpha$.

• Translational: m(du/dt + qw - rv) = X m(dv/dt + ru - pw) = Y m(dw/dt + pv - qu) = Z
• Rotational: I_x d p/dt - (I_y - I_z) q r = L I_y d q/dt - (I_z - I_x) p r = M I_z d r/dt - (I_x - I_y) p q = N
