The simulation results show that adaptive backstepping sliding model controller has high steady-state precision and strong anti-interference ability, therefore, it＇s suitable for hydraulic drive system speed control. The results proved that the modeling and control research is reasonable and effective, which lays the foundation for the effective control of the underwater tension leg platform and can provide reference for the research of similar products.
