Comparative Experiments in the Dynamics and Model-Based Control of Marine Thrusters
نویسندگان
چکیده
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.

Preliminary experiments in the model-based dynamic control of marine thrusters
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. ...
متن کاملPreliminary Experiments in Model-Based Thruster Control for Underwater Vehicle Positioning
This paper reports comparative experiments with two novel and one conventional thrust control algorithms for the unsteady (transient) control of thrust generated by conventional bladedpropeller marine thrusters. First, comparative experiments with three different thrust control algorithms over a wide range of unsteady operating conditions suggest that model-based control algorithms offer transi...

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 کاملInvestigation of stepped planning hull hydrodynamics using computational fluid dynamics and response surface method
The use of step at the bottom of the hull is one of the effective factors in reducing the resistance and increasing the stability of the Planning hull. The presence of step at the bottom of this type of hulls creates a separation in the flow, which reduces the wet surface on the hull, thus reducing the drag on the body, as well as reducing the dynamic trim. In this study, a design space was cre...
متن کاملA Comparative Study on the Formability Prediction of Two-Layer Metallic Sheets
Two-layer metallic sheets have wide applications in aerospace, marine, automotive and domestic industries due to their superlative characteristics. In this paper, the formability of two-layer sheet is investigated through analytical, experimental and numerical approaches. An analytical model is developed based on Marciniak-Kuczynski method associated Hill’s non-quadratic yield criterion. Formin...
