Research on intelligent test system for solenoid valve

Abstract

The solenoid valve is a key control element of hydraulic system which plays a decisive role in the reliability and the level of automation of the equipment. An intelligentized, comprehensive and high efficient test system of solenoid valve is designed in this paper. The mathematical model of the test system is built after ignoring the unimportant factors, and the visual modeling is built with the AMESim software. Fuzzy turning PID controller which changes the three parameters of PID controller by the error and error's varieties of systems is used to control the system pressure; the performance of system is obtained by simulating with combining MATLAB/Simulink and AMESim. 5Bar, 15Bar and 25Bar are given as the target value, and the best controlling strategy after the analysis and comparison is got to improve the test efficiency and test results of solenoid valve.
