Modeling and Co-Simulation for Hydraulic System of Test-Bed of Semi-Automatic Coupler Draft Gear Based on AMEsim/Simulink
When the test-bed tests semi-automatic coupler draft gear of the metro vehicle in the case of maximum lateral swinging angle, it requires a hydraulic motor to move the adjustable bearing base which is linked with coupler draft gear in a certain distance until it achieves the desired Angle. In this article, we adopt the valve-control motor electro-hydraulic position servo control system, in which it has the angular measuring device. Besides we optimize the effection of control system by using the fuzzy strategy. Through the AMEsim/Simulink co-simulation and analysis, the level swinging angle of coupler draft gear shows accurate, reliable and stable, which reaches the expected effection completely. With the more and more complex of the controlled object, this kind of intelligent control strategy gives an effective solution for solving complex problems.
