چکیده

This paper presents a digital resolved acceleration control method for coordinated motion control of an underwater vehicle equipped with manipulators. Using this method, in spite of large position and attitude errors of the underwater vehicle, good control performances of the end-tips of the manipulators to follow a pre-planned trajectory can be achieved. In this work, theoretical work of the proposed method is described. Then, the effectiveness of the proposed method is demonstrated through experimental work using a 3-link dual-arm underwater robot in actual underwater environment.

Experiments in the coordinated control of an underwater arm/vehicle system

The addition of manipulators to small autonomous underwater vehicles (AUVs) can pose significant control challenges due to hydrodynamic interactions between the arm and the vehicle. Experiments conducted at the Monterey Bay Aquarium Research Institute (MBARI) using the OTTER vehicle have shown that dynamical interactions between an arm and a vehicle can be very significant. For the experiments ...

Nonlinear Robust Tracking Control of an Underwater Vehicle-Manipulator System

This paper develops an improved robust multi-surface sliding mode controller for a complicated five degrees of freedom Underwater Vehicle-Manipulator System with floating base. The proposed method combines the robust controller with some corrective terms to decrease the tracking error in transient and steady state. This approach improves the performance of the nonlinear dynamic control scheme a...

QFT Control of a Two-Link Rigid-Flexible Manipulator

This paper evaluates a new and simple controller design method based on QFT (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. A piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. This system is modeled as a nonlinear multi-input multi-output (MIMO) control systems whose inputs are two...

Dynamic Analysis and Active Damping Control for Underwater Vehicle-Manipulator Systems

Underwater vehicle-manipulator (UVM) systems have been suggested for inspection, maintenance, repair and construction of underwater structures. The addition of manipulators to the vehicle makes control of the system more difficult due to the interaction forces between vehicle and manipulator. So, the efficient compensation of those interactions should be considered for accurate control of both ...
