Abstract
Hydro power stations are normally controlled by PID-controllers. One example is the Torsebro hydro power plant in Helge river. The Southern Sweden Power Supply (Sydkraft SB) initiated a research project addressing the water level control problem of hydro power plants. <br><br> The goal of this master thesis was to investigate the level-control problem.
