Question

8.5(C). The Wright Flyer was statically and dynamically unstable. However, because the Wright brothers incorporated suficient control authority into their design they were able to fly their airplane successfully. Although the airplane was difficult to fly, the combination of the pilot and airplane could be a stable system. In [8.5] the closed-loop pilot is represented as a pure gain, kp, and the pitch attitude to canard deflection is given as follows 11.0(s 0.5)(s 3.0) 6. (s2 + 0.72s + 1.44)2 5.9s - 11.9) Determine the root locus plot of the closed-loop system shown in Figure P8.5. For what range of pilot gain is the system stable? Pilo Airframe kp eo Visual feedback FIGURE P8.5
