measurement & control
KEY-enabling TECHNOLOGY
Measurement, control and analysis are essential for acquiring knowledge from numerical and experimental studies. This programme provides the tools and techniques needed to gain insight into full-scale and model-scale physics.
COLLECT DATA TO INCREASE KNOWLEDGE
The current trends in measurement and control (M&C) technologies for hydrodynamic testing are towards the application of new sensor technologies, data fusion, vision based measurements and the interaction with control systems. In addition, the application of Model-in-the-Loop (MIL) tests is growing and enabling complex experiments with a hybrid solution consisting of physical and simulated system parts.
Mathematical analysis and the application of data science is used to gain information from large amounts of measured data. This information can then be used to help research programmes improve their knowledge of theoretical models, control system, numerical tools and marine designs.

SUB PROGRAMMES
MEASUREMENT
Measurements are performed to extract quantitative information from both physical processes and simulated system parts in Model In the Loop experiments. Applied technologies range from transducers which directly convert sensed quantities into electric signals to optical or camera based measurement systems with dedicated processing. In addition to measuring the physical processes, a vital role is played by data collection, post-processing, hardware engineering and software engineering to deliver instrumentation and registrations that are fit for purpose.

Control
Control is used to let a system behave as we require, or to create a stable environment for experimentation. The aim of this sub-programme is to systematically, but more importantly transparently, design and tune controlled systems.

QUALITY
Quality aims at quantifying the uncertainty in measurement results and improving the quality of measurement chains by improving the understanding of:
- the contributions to measurement uncertainty from individual system components and from environmental conditions.
- methods to combine these contributions to a confidence interval of the higher levels of information provided by the experiment including the analysis.
- the contributions to measurement uncertainty from individual system components and from environmental conditions.
- methods to combine these contributions to a confidence interval of the higher levels of information provided by the experiment including the analysis.

STEREO PARTICLE IMAGE VELOCIMETRY
PIV is an advanced, optical measuring technique for obtaining 3D velocity information in a plane. The flow measurement with PIV is based on the measurements of the displacement (Δx) of a particle in a target plane between two successive light pulses with time delay (Δt). The flow is seeded with particles and the target plane is illuminated with a laser light sheet. Then the particle positions are recorded by two digital cameras.
