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 PBMR.

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 8 full time academics across the engineering disciplines of electrical, mechanical and chemical and numerous postgraduate students. Up to the end of 2016 the group has delivered in excess of 50 Masters students and 13 PhD students. In terms of publication, in excess of 35 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 Pebble Bed Modular Reactor (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.

Research Focus

  • Energy-based analysis of large-scale industrial plants.

  • Energy-based control and fault detection and diagnosis of large-scale industrial plants.

  • Modelling of high speed AMB-supported rotor drops onto backup  bearings; a qualitative approach to rotor drop severity.

  • Pattern recognition applied to condition monitoring and medical  screening tests.

  • Modelling of electrical machines; with a special emphasis on thermal modelling.
