Aims

To develop knowledge and understanding of:

A1. Mathematical modelling and its fundamentals
A2. Control theory and its basic applications
A3. Rationale and procedures for modelling, simulation and analysis of marine machinery systems
A4. integrated analysis of steering, propulsion, transmission and stabilisation systems

Outline Of Syllabus

The lecture material will cover:

Introduction to control engineering, open and closed loop systems, mathematical modelling of mechanical, hydraulic and electrical system components, linearisation, solution of 1st and 2nd order differential equations, Laplace transforms and their application, initial and final value theorem, state- space representation, transfer functions, block diagrams, poles and zero, time response, Routh- Hurwitz stability theorem, frequency response methods, relative stability, design of feedback control systems, bode diagrams, nyquist diagrams, gain and phase margins, closed loop analysis, root locus diagram and controller design. Marine system identification. Modelling, control and simulation of hydraulic (actuators, motors and pumps) and electric systems (passive and active networks, DC/AC motors and actuators), on-board ships for applications of governing speed of an engine, power transmission, ship dynamic stability and manoeuvring, system identification, controllability and observability assessment techniques.

The laboratory study will cover:
the modelling of engineering systems in a micro controller, Labview and Matlab/Simulink to study control system design to improve dynamic performance.

Intended Knowledge Outcomes

On completing this module, students will be able to demonstrate knowledge and understanding of:

IKO1. Limiting criteria affecting design and implementation of control systems,
IKO2. Control system design principles and rationale,
IKO3. Performance characterisation and stability of closed loop systems,
IKO4. Application of systems analysis and synthesis to marine machinery systems,
IKO5. Interaction of control systems with mechanical, electrical and hydraulic systems.

Intended Skill Outcomes

On completing of this module students will be able to develop the following subject specific skills:

ISO1. Application of modelling and simulation procedures,
ISO2. Simulation and analysis of systems performance,
ISO3. Identification of the limitation on conventional control system designs,
ISO4. Selection of appropriate control system for a wide range of marine machinery types,
ISO5. Definition, calculation and analysis of the effects of nonlinearities in control system design and marine
system operations,
ISO6. Integration of the effects of various operational conditions into marine machineries performance
characteristics.

Teaching Rationale And Relationship

The use of lectures as the principal teaching method is justified by the need to assist students in the acquisition of a knowledge base that will facilitate understanding of a sizeable and detailed body of materials. (IKO1-5)
Tutorials provide a forum in which students are given opportunity to develop subject-specific skills, negotiate their problems with tutors and their peers in a less formal approach. (ISO1-3)

Coursework which is based on development of a simulation and analysis program will provide a platform for active participation to exercise cognitive skills, planning, problem-solving, numeracy skills and computer literacy. (ISO1-6)
Independent study includes: Directed study following lectures,

Self-directed and directed study relevant to assessed project, which affords an opportunity to bring together relevant knowledge, subject specific and assessed key skills.
Alternative will be offered to students who are unable to be present in person.

Assessment Rationale And Relationship

The examination affords students an opportunity to demonstrate knowledge, understanding and possession of subject specific and key skills. The medium also allows students to demonstrate intended learning outcomes across a wide range of topics within a syllabus under time-limited conditions, this being a valuable metric for any subsequent employer.

The computer-based simulation laboratory work (the coursework) assess their ability to perform dynamic modelling simulation, interpretation and presentation, without a tight time limit.
