Design of Fuzzy-PID controller using logarithmic approximations for IMC-LFC Model
Abstract
This paper provides a Artificial Intelligent controller layered to analyze the power system’s logarithmic load frequency control problems. The control system ensures the preservation of steady frequency errors and of inadvertent bonding in a tolerance limit. The proposed control system was developed for a two-area hydrothermal heating system. The approach to control design is based on the two-degree internal model control (2DOF), which combines the fuzzy control technique for model order reduction to increase frequency excursions. Different techniques of the two-area reheating hydraulic energy system are integrated into the scheme and a correct combining of energy resources is seen in different operational conditions as a pragmatic solution. The IMC- FUZZY-PID architecture of the reduced order model, proposed with the original high order framework, delivers strong dynamic response and load sturdiness.
