DotX is developing the control system for a novel wind turbine design. This design is different from conventional ones for several reasons. For one, it carries multiple rotors. 

DotX has succesfully developed, implemented and tested the fine-tuning of the 0-pitch angles. This angle is initially set by a mechanic using a screwdriver, or a button and it sets the angle at which the balde is supposed to be at 0 degrees. The mechanic aligns the markers on the blade and in the nose-cone of the turbine. After that, a computer slowly adjusts the relative angles to rotor unbalance. After that, the computer slowly adjusts all blade angles in unison to find the angle that maximises power output of the turbine. 

 

Tests show that oscillations can be reduced by more than 80%, while yield can be improved 1 -2 % per year.

The PID Tuner software has now extended with a verification part. After the tuning, the PID Tuner guides the user in a verification procedure, where the behavior of the re-tuned PID response to a setpoint change is checked againts the simulated response. In addition, the user can verify the improvements, by toggling between 'old' settings and 'new' ones. After the toggle test, the statistics of the improvements are presented. 

All of the aformentioned features are presented in a report that the PID Tuner generates automatically. For an example of this report, click on this link to see an example: Click here to open a new tab with an example report

 

 

 

DotX is developing control software for a 3D printers to be used on-board of ships. When (small) ship parts break down, the part can be scanned and copied on board. This saves the shipping companies time and money. 

DotX and ABID (Alexander Bannink Industrial Design) are developing a novel 3d manufacturing machine. DotX develops all software to control the machine, while ABID takes care of the rest (mechanical design, and prototype building). The first prototype is planned to be ready in December 2019. 

The EU project TESTBED aims at developing innovative solutions for Smart Grids. Smart Grids are new methods of electricity distribution. The current way of electricty distribution consists, roughly speaking, of centralised electicity producers, and decentralised consumers of electricity. However, there is an ever increasing number of decentralised electricity generators, such as wind turbines, solar panels, etcetera. Furthermore, their electricty generation depends on the wheather. The traditional electricty supplier method: just make sure to meet the demand, is inefficient: if there is no demand, one has to get rid of the electricity. The idea of Smart Grids (Smart electricty distribution) is to allow (some of the) consumer appliances to adjust their demand based on the price of electricity. Smart Grids are not yet widespread. However, there are locations where these ideas are likely to be explored soon, such as islands with local electricity networks.

DotX is not likely to actively contribute to Smart Grid research, but instead, we will pick the brains of the researchers involved and try to 'steal' their ideas and convert them into commercial applications. Is that bad? No, this is what the EU and the researchers want us to do!
