% Design the pitch controller

% Design the yaw controller
t_settle = 8;
[N_y, ssobsctrl_y, sscl_y] = ss_design(yaw_sys, t_settle, ...

% Design the roll controller

% Set up the horizontal position controller gains

Kd = 5; % PD derivative gain

% Set up the cross coupling reduction gains
Cp =  0.10; % Roll Torque Compensation
Cq =  0.15; % Pitch Torque Compensation

% Set limits used in the controllers
