Passivity-based control applied to the dynamic positioning of ships

Passivity-based control applied to the dynamic positioning of ships

A family of passivity-based controllers for dynamic positioning of ships is presented. The authors exploit the idea of shaping the energy function of the closed-loop system to obtain different formulations of the passivity-based control law using the interconnection and damping assignment-passivity-based control (IDA-PBC) methodology. A salient feature of this study is that the proposed control...

Output Feedback Passivity Based Controllers for Dynamic Positioning of Ships

Optimization-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 –...

Fuzzy Control of Dynamic Positioning Systems for Ships

In this paper we consider the control problem of Dynamic Positioning Systems for Ships (DPSS). It interests as a case which study in nonlinear controller design because the model exhibits nonlinear interaction in three degrees of freedom (surge, sway, and yaw) by means of main propellers aft of the ship. The DPSS system considered in this paper is modeled by a Takagi-Sugeno (T-S) type fuzzy mod...
