Robust control of automatic voltage regulator (AVR) with real structured parametric uncertainties based on H and μ-analysis.

Within this work, a novel controller in terms of H infinity (H) and structured singular value decomposition has been presented to provide the robust performance of the Automatic Voltage Regulator (AVR) system Six real structured uncertainties in actuator, exciter and generator have been assumed for the linear transfer functions of the AVR system. Each uncertain parameter varies between a minimum and a maximum value due to the load variations in a period of time and aging effects over the life time. The efficiency of the presented design lies on two main reasons.
