    • Design synthesis of LCC HVDC control systems. 

      Chetty, Leon. (2011)
      From the early days of HVDC system applications, the importance of mathematical modelling of the dynamics of Line Commutated Converter (LCC) HVDC systems has been appreciated. There are essentially two methodologies used ...
    • Quantitative Feedback Theory design of line current commutated HVDC control systems. 

      Chetty, Leon.; Ijumba, Nelson M. (SAIEE Publications., 2013)
      Line Current Commutated (LCC) HVDC systems consists of uncertain plants. These uncertainties are result of changes/disturbances in the ac networks or in the LCC HVDC system itself. Further uncertainties can be introduced ...
    • Rural electrification using overhead HVDC transmission lines. 

      Chetty, Leon.; Ijumba, Nelson M. (Energy Research Centre., 2012)
      One of mankind’s greatest modern challenges is poverty alleviation. The provision of electricity can greatly assist in this regard. The tapping of small amounts of power from an HVDC transmission line represents a solution ...
    • System identification of classic HVDC systems. 

      Chetty, Leon.; Ijumba, Nelson M. (SAIEE Publications., 2011-12)
      Determining models from observations and studying the models’ properties is essentially the functionality of science. Models attempt to link observations into some pattern. System identification is the art of building ...
