Two kinds of discontinuous control methods i, e., simple on-off(SOF) control and pulsating on-off(POF) control methods are implemented and compared each other for a low cast hydraulic position-control system which utilizes a solenoid-operated directional valve instead of a servovalve. Experimental work was carried out to investigate effects of control parameters and loading conditions on step response characteristics of the system for each control method. The results show that much higher accuracy and much better transient response characteristics can be achieved by POF controller than those by SOF controller. The results may be used as basic data in the selection of control parameters as well as in the design of the hydraulic position-control system.
