Dynamic Surface Adaptive Robust Control of Unmanned Marine Vehicles with Disturbance Observer

Abstract EN

This paper presents a dynamic surface adaptive robust control method with disturbance observer for unmanned marine vehicles (UMV).

It uses adaptive law to estimate and compensate the disturbance observer error.

Dynamic surface is introduced to solve the “differential explosion” caused by the virtual control derivation in traditional backstepping method.

The final controlled system is proved to be globally uniformly bounded based on Lyapunov stability theory.

Simulation results illustrate the effectiveness of the proposed controller, which can realize the three-dimensional trajectory tracking for UMV with the systematic uncertainty and time-varying disturbances.
