【Abstract】 In view of the features of such controlled parameters as pressure and flowrate and changeful test conditions including nonlinearity,time-varying uncertainty and certain hysteresis,an integrated control method was proposed for the testing system of solenoid valve. The mathematical models based on the testing system of the solenoid valve loop with oil as medium were developed,and the integrated intelligent control algorithm was introduced to implement the accurate control of parameters. An electro-hydraulic control simulation was done with the algorithm via Matlab/Simulink,and the results were analyzed comparatively to verify the effectiveness of the control algorithm. Then,the control algorithm was introduced into the test of solenoid valve,and an optimal integrated control strategy was determined for the system via comparative analysis.更多还原
