Detailed description of topics:

Theoretical background:

Signal conditioning

* Analogous and digital signal processing, amplifiers, filtering

Measurements techniques

* Analogue and digital equipment, applicability, implications of sampling, D/A and A/D conversion

Sensors

* Working principles, interpreting sensor specifications

Actuators

* Working principles DC drives, servo acuators, determine and interpret characteristics

Dynamics

* Modelling manoeuvring of ships, control requirements for weather vaning dynamic positioning and dynamic tracking

Practical application:

Determine characteristics of available sensors and actuators and the available scale model. Design and implement a weather vaning DP/DT controller for use on the scale model in the towing tank. Demonstrate the controller in the towing tank.

Course material:

• 'Dynamic positioning of vessels at sea'; Pinkster
• 'A Study on Weather Vaning Dynamic Positioning System`; Pinkster, Hagiwara, Shoji, Fukuda
• Additional material to be determined

References from literature:

• `Feedback Control of Dynamic Systems`; Franklin, Powell, Emani-Naeini
• `Onboard Experiments on Weather Vaning Dynamic Positioning System`; Pinster, Hagiwara, Shoji, Fukuda

Remarks assessment, entry requirements, etc.:

The project assessment is based on:

* Theoretical analysis and solution (report)

* Practical results of the controller (from experiments conducted in towing tank)

Learning goals:

Understand the basic principles of mechatronics: the combination of mechanical, informatical, electronical aspects into one system

Describe sensors principles and to apply sensors for suitably measuring position (6 d.o.f.), speed, acceleration, force, torque, rpm, flow speed, sine/cosine, acoustics etc) by different means (electrical, optical, acoustical etc.)

Describe actuator principles and to apply actuators for marine purposes (load characteristics, response speeds, geometrical parameters, durability)

Apply the basics of signal processing relevant to mechatronical systems (sampling, filtering, transformation, functional processing, A/D and D/A conversion)

Apply the basics of computer based measuring and control

Analyse and interpret the performance of a simple mechatronical system

Apply the ergonomical aspects of mechatronic systems (safety, operation, access) and the organizational impacts (working conditions, lay-offs, educational requirements etc)

Evaluate the strength and weakness of a mechatronical system  

Computer use:

Matlab / Simulink, Humusoft real time toolbox

Laboratory project(s):

Implementation of the DP/DT controller in a real-time environment to control a model in the towing tank.

Experiments in the towing tank to demonstrate the solution.
