- Abstract
Closed-loop control or open-loop control of proportional valve can be completed when the drive current of electro-hydraulic proportional valve is provided by electro-hydraulic proportional amplifier. The control performance of proportional valve can be directly decided by the electro-hydraulic proportional amplifier. Electro-hydraulic proportional control amplifier is an important part of the control system of electro-hydraulic proportional. so the application research of electro-hydraulic proportional control amplifier has an important value and significance. In this article, development and composition of proportional control amplifier are simply introduced; Working principle of proportional control amplifier is discussed; Working principle of electro-hydraulic proportional amplifier on control circuit and driver circuit is analyzed; Working principle of the key components of the electro-hydraulic proportional control amplifier are described, and the application foreground of electro-hydraulic proportional amplifier is prospected. Combined with some new technologies of PID control, the state feedback control, adaptive control, variable structure control and fuzzy logic control, it is pointed out that electro-hydraulic proportional amplifier will be in this direction of state feedback control, adaptive control, variable structure control and fuzzy logic control, etc.
