Abstract
The nonlinear factors, the external interference, and the coupling between the two hydraulic cylinders in the electro-hydraulic position servo system seriously affect the synchronous control accuracy. In this paper, based on the establishment of the state space equation of double hydraulic cylinders, the cross-coupling control structure was adopted, and the synchronous controller based on dynamic soft variable structure control was designed. The synchronous controller based on sliding mode control was used as a comparison for co-simulation and experimental analysis. The results showed that under the control of two synchronization controllers, the controlled dual cylinders could track the given positioning signal in a short time, and the synchronization error was always within the specified range. The synchronization controller based on dynamic soft variable structure control could shift smoothly without significant impact when the given positioning signal suddenly changes, avoiding the chattering problem in the sliding mode control.
