Abstract This thesis addressed model identification and the design of two different controllers applied to load frequency control of single and two interconnected areas of non-reheat steam turbine. The first controller used in this thesis is PI controller with two methods for tuning its parameter, Ziegler -Nichols (Z-N) Method and fuzzy logic controller.The other controller in this thesis is variable structure control (VSC) with sliding mode and using genetic algorithm to find the optimum switching vector and feedback gains. Problems in VSC were considered, chattering and feedback gains. Finally compare between the conventional PI controller and variable structure control |
