A motion-control system includes an operator interface with an operator-input member and a controllable force feedback device drivingly connected to the operator-input member. The motion-control system may also include controls that regulate the motion of one or more moveable components, including adjusting a first operating parameter in a manner that depends at least in part on a control error between a target value of a second operating parameter and an actual value of the second operating parameter. The target value of the second operating parameter may be based at least in part on the motion of the operator-input member. The controls may also operate the controllable force feedback device to provide feedback force on the operator-input member in a manner that depends at least in part on the control error and such that the derivative of the feedback force with respect to the control error varies dependent at least in part on the control error.
