Research on Load Displacement Tracking Control of Shock Absorber Test Bench Based on Robust Adaptive Control
Damping dampers are the core components used for vibration reduction in buildings,bridges,wind power,pipelines,and other fields.The damping damper test bench is a testing device for testing the dynamic/static characteristics of damping dampers.In response to the problem of large tracking errors between the actual displacement and the expected displacement of the shock absorber test bench during displacement loading,a mathematical model of the hydraulic servo displacement control system of the test bench is established,a robust adaptive controller is designed,and the stability of the controller is verified based on Lyapunov theory.A displacement tracking control method based on robust adaptive is proposed.Build a Simulink and AMESim joint simulation model to simulate and analyze the control methods of the electro-hydraulic servo system on the test bench;Build a test bench and compare and verify the control performance of robust adaptive controllers and traditional PID controllers.The experimental results show that the robust adaptive controller has strong anti-interference ability,reduces tracking error by 55％,improves response speed by 66.7％,and greatly improves the displacement tracking control accuracy of the loading system of the test bench.
