I want to design a missile with tails while controlled with canard fins. The question is how to make the missile of critical damping in its pitch-mode response to the elevator (actuator-fin) deflection? I mean I want to meet a critically damped response of pitch-angle dynamics to canard-fin deflections (actuation). Although the missile is spinning but if you answer about spin-stabilized missile, your answer is also welcomed. I do not want any oscillatory motion in pitch-mode (only pure damping is sought). You can imagine rolling-airframe missile RIM116 as my design goal and reply with regard to that.
