Question: Using the Dutch roll approximation, determine the state feedback gains so that the damping ratio and frequency of the Dutch roll are 0.3 and 1.0

Using the Dutch roll approximation, determine the state feedback gains so that the damping ratio and frequency of the Dutch roll are 0.3 and 1.0 rad/s, respectively. Assume the airplane has the following characteristics:

Y = -19.5 ft/s Ng=1.5s- = 4.7 ft/s uo = 400 ft/s

Y = -19.5 ft/s Ng=1.5s- = 4.7 ft/s uo = 400 ft/s Yor Y,= 1.3 ft/s N,= -0.21 S- Nor= -0.082 s-
