About me – Philip de Vaal
I am a full professor of chemical engineering at the University of Pretoria, and am a guest professor in the Future Energy Center at MDH. I specialise in process modelling and control, and have been teaching courses in process dynamics and in process control at undergraduate and postgraduate level since 1980. My specific interest is in modelling and control of large, ill-defined and difficult to monitor nonlinear systems with varying dynamics, such as found in the paper and pulp, minerals processing and petrochemical industries. A special parallel focus is on laboratory evaluation of lubricant performance and the effects this has on energy consumption in large industrial processes. A total of 37 master's degrees and three PhD's have been awarded under my supervision.
My educational and professional background
I graduated from the Department of chemical engineering, University of Pretoria, Pretoria, South Africa with a bachelor’s degree in chemical engineering in 1976, followed by a master’s (1980) and a PhD (1990) from the same institution. After some years in industry, I joined the staff of the same department in 1980 as a senior lecturer.
My research intrerest
I established a laboratory for advanced process control in the Department of chemical engineering in 1987. The apparatus in the laboratory represent unique measuring and control phenomena like interactivity, nonlinearity and dead-time. To date, more than 100 candidates have completed the postgraduate specialisation programme in control engineering, BEng(Hons)(Control Engineering), which I developed. Research focus is concerned with relating process modelling and control to plant-wide performance. In 1990 I also established a tribology laboratory where specific research is conducted on laboratory evaluation of lubricant performance. A special interest is modelling of tribological systems and the effect of lubricants on energy reduction in industrial processes.
