Networked sliding mode control for leveling subsystem of multi-axle transportation vehicles

Multi-axle transportation vehicles usually adopt distributed electro-hydraulic proportional systems based on network to perform the complicated manipulation and control functions. Aiming to the adverse effects caused by network induced time delay, a networked sliding mode control strategy for leveling subsystem of multi-axle transportation vehicles is presented. The model of distributed leveling subsystem is established. By combining the augmented state function with discrete sliding mode control, the time-varying network induced delays in feedback and forward loops are compensated to promote the robustness of system. Simulation study on actual leveling subsystem (DCY100) is carried out to verify networked sliding mode control strategy.
