    OVERVIEW

    Introduction, study and analysis of the fundamental components of automation marine systems.

    AIMS AND CONTENT

    LEARNING OUTCOMES

    Automation and control are essential functions for the ship correct and efficient management. The course presents the fundamental concepts of automatic control enabling the student to deduce mathematical models and to synthetize controllers by a practical approach for the dynamic systems of plants, processes and time-varying behaviors in electric, thermal and mechanical marine applications.

    AIMS AND LEARNING OUTCOMES

    The aim of the course is to provide the fundamental concepts of marine automation systems.

    In order to understand these aspects, it is necessary to introduce the basics of the control theory, starting from the description of the system and focusing on the analysis of linear/linearizable systems. Notions for the use of transforms for linear systems and tools for the analysis and synthesis of control systems are provided. Practical examples of marine applications are illustrated in order to facilitate the comprehension of automatic controls.

    The fundamental knowledge in Information and Communication Technology (ICT) related to marine automation systems is provided with a particular attention to the most common communication systems/protocols.

    The characteristics of a generic metering system are described together with the sensors that are used on board. The main actuators and regulators are then examined.

    The course contents are calibrated following the "IMO model Courses for chief Engineer and Electrotechnical Officer".
