STUDY ON PARALLEL CONNECTED HYDRAULIC POSITION CONTROL SYSTEM

Abstract

Abstract: One type of hydraulic control system is discussed. It consists of two valves, one is a small flow rate valve, which can control the hydraulic flow continuously and has high dynamic performance, the other is a large flow rate valve, which only has on-off capacity. They are parallel connected to control the hydraulic cylinder. The control strategy, stability conditions and position control performances are discussed. As an example, a parallel connected proportional valve and directional valve position control system is studied.

Key words: Electrohydraulic proportional control, Parallel connected control, Position control, Stability
