Modeling And Simulation Of Force Control System Of Triaxial Testing Machine Based On Amesim/Simulink

A servo force control system based on iterative learning control algorithm is proposed for the characteristics of nonlinear, strong cross coupling and parameter uncertainty of triaxial loading hydraulic servo system. Through the mathematical modeling of hydraulic servo force control system to determine the control parameters of the iterative algorithm, finally, the AMESim/Simulink is used to model and combine the simulation. The simulation results show that the control method can effectively improve the control accuracy of the three-axis loading servo-control system and improve the response speed of the system.
