The Bell-Boeing V-22 Osprey tiltrotor is both an airplane and a helicopter. It's advantage is the ability to rotate its engines and rotors to vertical position for take-off, landings, and helicopter flight. Then, rotate to a horizonal position to cruise like an airplane. The altitude control system is shown below. (a) Controller Dynamics K+ 1.5+ 0.5) RG) (20 + 1)(10 + 10.5+ 1) Altitude Consider the disturbance input to be zero. MATLAB functions that might come in handy include conv, roots, rlocus, plot, axis, sgrid, rlocfind, tf, feedback, step, and grid.
