Preliminary experiments in the model-based dynamic control of marine thrusters

چکیده
This paper presents experiments with a new algorithm for the unseady (tranient) thrust control bladed-propeller marine thrusters. Comparative experiments over a wide range of unsteady operating conditions with three different thrust control algorithms demonstrate the model-based control algorithm to offer transient thrust-control performance superior to that of its non-model-based counterpart. The use of improved unsteady thrust control on underwater vehicles promises to reduce the well-documented limitcycling of dynamically-positioned marine vehicle position during low-speed manuevering.

Comparative Experiments in the Dynamics and Model-Based Control of Marine Thrusters
This paper examines dynamical models for bladedpropeller type marine thrusters. Previously reported thruster dynamics models are reviewed, and a new simplified model is proposed. Experimental testing of both the transient and steady-state performance of a marine thruster corroborates previously reported data, validates the simplified thruster model, and raises new questions.

Biomimetic underwater vehicle design has attracted the attention of researchers for various reasons such as ocean investigation, marine environmental protection, exploring fish behaviors and detecting the leakage of oil pipe lines. Fish and other aquatic animals have good maneuverability and trajectory following capability. They also efficiently stabilize themselves in currents and surges leave...
متن کاملOptimization-based control of diesel-electric ships in dynamic positioning
Recent advances in computer hardware and algorithms make it possible to consider more computationally demanding control methods, allowing more effective exploitation of the equipment under control. This thesis explores new ways of controlling ships (or other marine vessels) that are designed to keep a predetermined position and heading automatically exclusively by the means of their thrusters –...
