I agree with much of what John Denker wrote. I would add to my comments above that: 1) Don't filter pilot inputs artificially for normal flight activities, 2) You can rate-limit actuators (in JSBSim aircraft models) where it is appropriate to model such things. In a C-172, for instance, that would not be needed, because there is a direct connection between the stick and rudder. For the space shuttle or a modern launch vehicle, you would of course need a higher fidelity actuator model that includes hysteresis, deadband, bias, and rate- and position-limiting.
