Motion-control system
First Claim
1. A motion-control system, comprising:
- an operator interface, includingan operator-input member;
a controllable force feedback device drivingly connected to the operator-input member; and
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 being based at least in part on the motion of the operator-input member; and
wherein the controls 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.

Abstract
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.

11. A method of operating a motion-control system, comprising:
-
adjusting the value of a first operating parameter of the motion-control system based 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; determining the target value of the second operating parameter of the motion-control system based at least in part on the motion of an operator-input member of an operator interface of the motion-control system; and operating a controllable force feedback device drivingly connected to the operator-input member 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 as a function of the control error. - View Dependent Claims (12, 13, 14, 15)

16. A steering system for a mobile machine, comprising:
-
an operator interface, including an operator-input member; a controllable force-feedback device drivingly connected to the operator-input member; controls that operate the controllable force feedback device to provide feedback force on the operator-input member based at least in part on a control error between a target value of an operating parameter of the steering system and an actual value of the operating parameter, wherein the controls regulate the feedback force in a manner such that the derivative of the feedback force with respect to the control error decreases at a first positive control error value, and the derivative of the feedback force with respect to the control error increases at a second positive control error value, the second positive control error value being higher than the first. - View Dependent Claims (17, 18, 19, 20)
