Compare the roll rate time response with and without the following aileron actuator model. Use an aileron doublet input, with 2 degree amplitude and duration of two seconds for each step. F-16 roll mode: p = 2.35 p 41.86 a (p in rad/s, delta_a in rad) aileron actuator: a = 10.0 a 10.0 ac (delta_a, delta_ac in rad)...
