    • Comparison of Recursive Parameter Identification Techniques for Computer Control of Power Systems 

      Sheirah, M. A.; El-Sayed, M. A. H. ( Qatar University , 1988 , Article)
      This paper outlines the main features of parameter identification in electric power systems. A series of recursive parameter identification techniques is presented, this containing the generalized — and extended least ...

    • Control Algorithms Of Digital Automatic Voltage Regulators For Synchronous Generators 

      Badr, M. A. L.; Eteiba, M.B.; El-Zawawi, A.M.O. ( Qatar University , 1990 , Article)
      The main concepts of the application of digital controllers to a power system as automatic voltage regulators are presented in this paper. An experimental study using a physical model of a limited size power system has ...

    • A Model Reference Adaptive Control Scheme with External Controllers 

      Al Salman, Riyadh; Nagarajan, R.; Jerwe, Dakhil H. ( Qatar University , 1989 , Article)
      A new model reference adaptive control scheme, suitable for linear multivariable discrete time systems, is proposed. A set of parameter adaptation algorithms are developed based on the validity of perfect matching between ...

    • Simulation of Cross-Current Extraction Processes 

      Salem, A. B. ( Qatar University , 1988 , Article)
      Extraction processes dealing with partially miscible solvents are usually calculated by graphical methods to estimate the number of stages required, flow rates and compositions of the streams. Such procedures may be lengthy. ...
