Abstract
A position control system having dual controllers, each capable of operating in either a proportional or a proportional plus integral gain mode, is normally operated with one controller in the proportional plus integral mode and the other in the proportional mode, each controller contributing its proportionate part of the output position control signal to the position controlled device, and each controller capable of operating alone in the proportional plus integral mode in the event of a failure.
