    • Automated control of mine dewatering pumps 

      Smith, Tinus (2014)
      Deep gold mines use a vast amount of water for various purposes. After use, the water is pumped back to the surface. This process is energy intensive. The control is traditionally done with manual interventions. The purpose ...
    • Best practices for automation and control of mine dewatering systems 

      Oberholzer, Phillip Johannes (2015)
      Typical deep level mines use up to 27 ML water per day for mining operations. Multistage centrifugal pumps up to 2500 MW are used in an upward cascading manor to dewater the shaft. The dewatering systems at some mines are ...
    • Deterministic micro-controller selection method for complex control algorithms 

      Bloem, Johannes Hendrik Daniël (North-West University (South Africa), 2019)
      This dissertation presents a method for selecting a micro-controller unit (MCU). The driving force behind this method is to determine whether or not a MCU will have enough processing power for a complex control algorithm ...
    • Load shift through optimal control of complex underground rock winders 

      Buthelezi, Mzwandile Arthur (North-West University, 2009)
      South Africa's national power utility, Eskom, initiated a Demand Side Management (DSM) drive to help alleviate the electricity supply shortage experienced in South Africa. The focus of this study is on a load-shifting ...
    • Model based predictive control for load following of a pressurised water reactor 

      Human, Gerhardus (North-West University, 2009)
      By September 2009 the International Atomic Energy Agency reported that the number of commercially operated nuclear reactors in 30 countries across the world is 436, around 50 reactors are currently being constructed, 137 ...
    • Model predictive control of a Brayton cycle based power plant 

      Lusanga, Peter Kabanda (2012)
      The aim of this study is to implement the model predictive control in order to optimally control the power output of a Brayton cycle based power plant. Other control strategies have been tried but there still exists the ...
    • Reducing energy consumption on RSA mines through optimised compressor control 

      Booysen, Walter (North-West University, 2010)
      South Africa experienced a severe shortfall in electricity supply during 2008. Eskom, the national electricity supplier, implemented several strategies to alleviate the situation. The Power Conservation Programme set the ...
