The target input is clipped to X_TARGET_LIMIT. The output of a PI controller is named dXdT because it gives
the desired derivative d/dt as a target value to the following stage: The position (x) controller gives velocity
(dx/dt). The output of the PI Controller is clipped to dXdT_LIMIT. The error integral of (20) is clipped to
dXdT_LIMIT / I in the classic controller structure, and the integrator output is clipped to dXdT_output_limit
in the advanced controller structure.
