Fuzzy -PLC PID Simulink implemented AVR system to enhance the transient response of synchronous generator

摘要

A novel design a fuzzy proportional integral derivative (PID) controller is using Matlab and programmable logic controllers (PLCs) for a set point voltage control problem in the automatic voltage regulator (AVR) system. The controller objective is to maintain the terminal voltage all the time under any loads and operational conditions by attaining to the desired range via the regulation of the generator exciter voltage. The main voltage control system uses PLCs to implement the AVR action. The proposed fuzzy controller combines the genetic algorithm (GA), radial-basis function network (RBF-NN) identification and fuzzy logic control to determine the optimal PID controller parameters in AVR system. The RBF tuning for various operating conditions is further employed to develop the rule base of the Sugeno fuzzy system. The fuzzy PID controller FPID is further designed to transfer in PLCs (Step 75.5) for implementing the AVR system to maintain the terminal voltage all the time under any loads and operational conditions for synchronous generator constant.
