Research on feedforward-feedback composite anti-disturbance control of electro-hydraulic proportional system based on dead zone compensation

HIGHLIGHTS

• What: The experiment shows that the dead zone of this proportional valve is ±20%. Combined Control Experiment Based on Dead ZoneofCompensation the red curve at points B and C, while the green horizontal dashed line representing a During the experiment, load disturbances were applied to the boom cylinder. The research findings are summarized as follows: After establishing the mathematical model of the electro-hydraulic proportional control system, a parameter identification method was used to identify the system`s transfer function, reducing the control system`s reliance on an accurate mathematical model.
