The performance is satisfactory but the linear responses showed a significant amount of
cross-coupling between axes and we could not quite meet the stability margins target at
the corner points of the (alpha,beta) range. Would it be beneficial to use a MIMO
architecture that combines all three measurements of phi, alpha, beta to calculate the
surface deflections? This idea is further explored in Part 4 of this series (“Attitude Control
in the HL-20 Autopilot - MIMO Design” (Control System Toolbox)).
