The name McTronX is an acronym after the field of mechatronics and was chosen due to the strong developments in the area of AMBs, a product of mechatronics, in the initial years since the establishment of the research group. This drive resulted in numerous laboratory demonstrator systems that today provide platforms for continued research. An equally strong activity involved the Modelling and Control and Condition Monitoring of different Brayton-cycle based configurations of the Pebble Bed Modular Reactor (PBMR) project.

The core activity of the McTronX research group is the Dynamic Modelling and Control of large-scale industrial systems or processes. Characteristic of the group is the multi-disciplinary nature of its projects. In terms of research capacity, the research group constitutes 7 academics across the engineering disciplines of electrical, mechanical and chemical and numerous postgraduate students. Up to the end of 2019 the group has delivered in excess of 60 Masters students and 16 PhD students. In terms of publication, in excess of 50 accredited journal articles have culminated from the research.


Prof. George van Schoor founded the research group in 2003 due to the research needs of the PBMR project under way in South Africa at the time.  The needs involved Dynamic Modelling and Control on the main thermohydraulic cycle as well as Active Magnetic Bearings (AMBs) that was seen as an enabling technology. 


Modelling and Control contributes to the improvement of industrial processes. The improvement can be quantified in terms of specific objectives of which energy efficiency, product quality or plant reliability is most prominent.
