In order to resolve the problem of frequency characteristic test of electrohydraulic proportional directional valves
a scheme for test control based on digital signal processor(DSP) is proposed.The overall structure and working principle of the test system is presented.The hardware system and software system are also designed.The experiment system of frequency characteristic test of electrohydraulic proportional directional valves is developed.Frequency characteristic of a kind of proportional directional valves is tested.The results show that the frequency characteristic test and control system of electrohydraulic proportional directional valves based on DSP is reliable and roboticized apparently
and the frequency characteristic test efficiency is also improved.
