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.
