Abstract
A control system for positioning an implement using a power steering unit. Instead of connecting a rotary spool of the power steering unit with a steering wheel, the rotary spool is connected with a DC motor through reduction gears. An angular displacement of a control lever is detected by an angular position detector and an angular displacement of an implement is detected by another angular position detector. Signals from both detectors are fed into a comparator which is connected with an amplifier for rotating the DC motor in either direction in response to signals therefrom.
