Closed-loop control system
First Claim
1. A control system for operating a device, comprising:
- a plurality of command elements generating command signals; and
a control element having a plurality of control modes, each control mode including a transfer function effective with a corresponding command signal as an input to operate the device in a predetermined manner and being selectable in accordance with the status of at least one of the command signals, wherein the transfer function output of a nonselected control mode is made to substantially track the transfer function output of a selected control mode such that the transfer function output of the nonselected control mode is substantially similar in magnitude to the transfer function output of the selected mode when the control element selects the nonselected mode.

Abstract
A control system for operating a device. The control system comprises a plurality of command elements generating command signals and a control element having a plurality of control modes. Each control mode includes a transfer function output effective to operate the device in a predetermined manner and is selectable in accordance with the status of at least one of the command signals. The transfer function output of a nonselected control mode is made to substantially track the transfer function output of a selected control mode such that the transfer function output of the nonselected control mode is substantially similar in magnitude to the transfer function output of the selected mode when the control element selects the nonselected mode. A method employs the system.

17. A control system for operating a device, comprising:
-
a first command element generating a first command signal; a second command element generating a second command signal; and a control element having at least two control modes, each control mode including a transfer function output effective to operate the device in a predetermined manner and being selectable in accordance with the status of at least one of the first command signal and second command signal, wherein the transfer function output of a nonselected control mode is made to substantially track the transfer function output of a selected control mode such that the transfer function output of the nonselected control mode is similar in magnitude to the transfer function output of the selected mode when the control element selects the nonselected mode. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
