Design and control of a hydraulic composite actuator for vibration simulation

Abstract: A hydraulic composite actuator is developed for vibration simulation. The hydraulic scheme and control principle are introduced and an open-closed-loop iterative learning control method is proposed for control issue. A special composite cylinder controlled by servo valve and proportional relief valve is designed to generate static force with large amplitude and dynamic force with small amplitude but high frequency. The control subsystem for dynamic force is a zero-type system with very high open-loop gain and … Show more

“…The use of numerical calculation to analyze the deflection in the operation process is difficult, inefficient, and almost impossible to complete. The use of simulation can greatly simplify the calculation process [4,5] and can be a more realistic simulation of the process of deflection of the movable crossbeam, to carry out the correction of the deflection.…”
