Automatic voltage regulators(AVR)are designed to manipulate a synchronous generator’s voltage level *** integral derivative(pid)controllers are typically used in AVR systems to regulate *** advanced pid tuning methods have been proposed,the actual voltage response differs from the theoretical predictions due to modeling errors and system *** requires continuous fine tuning of the pid ***,manual adjustment of these parameters can compromise the stability and robustness of the AVR *** study focuses on the online self-tuning of pid controllers called indirect design approach-2(IDA-2)in AVR systems while preserving *** particular,we indirectly tune the pid controller by shifting the frequency *** new pid parameters depend on the frequency-shifting constant and the previously optimized pid *** the frequency-shifting constant modifies all the pid parameters simultaneously,thereby improving the control performance and *** evaluate the robustness of the proposed online pid tuning method by comparing the gain margins(GMs)and phase margins(PMs)with previously optimized pid parameters during parameter *** proposed method is further evaluated in terms of disturbance rejection,measurement noise,and frequency response analysis during parameter uncertainty calculations against existing *** show that the proposed method significantly improves the robustness of the controller in the AVR *** summary,online self-tuning enables automated pid parameter adjustment in an AVR system,while maintaining stability and robustness.
