| Abstract: | How to eliminate the superfluous force of a loading system is one of the key problems to design a load simulator. In order to analyze the load simulator, using the bond graph modeling and simulation method, the expanded bond graph model of the load simulator combined with a ship steering electrohydraulic position servo system was established. And then, a hybrid control based on CMAC neural network was proposed. The performances of the proposed controller were evaluated through simulations. The simulation results show that the proposed controller can effectively eliminate the superfluous force and fairly improve the dynamic loading performances of the electrohydraulic load simulator than that of conventional constant PID controller with the compensation network based on the structure invariance principle. |
