摘要：
To achieve the highly reliable and highly accurate adjustment for electrohydraulic proportional pump A4VSO, an adjustment system is established, in which a servoproportional valve replaces a servo valve or a proportional valve. Then its mathematic model is obtained and simulated on Matlab/Simulink, and performance tests about pump displacement and output flow of the pump are carried out under different pressures. Both simulation and experimental results indicate that the adjustment system controlled by servoproportional valve is characterized by higher steady accuracy and more reliability, both the pump displacement and output flow of the pump A4VSO maintain proportional to the control signal, respectively.
