Design of FOPID Controller for Optimizing AVR System using Harris Hawk Algorithm

Abstract

The Automatic voltage regulator (AVR) system maintains the terminal voltage of the generation unit within safe limitations. But the performance is irregular and delayed. A controller is used in conjunction with the AVR system to improve this. In AVR, the FOPID Controller is the main component. FOPID beats the other controllers in terms of its control capabilities and tuning adaptability. The basic role of this examination is to decide how best to utilize this idea while making AVR, But the Tuning is more complicated due to FOPID's additional parameters (λ and μ). To overcome complexity in this research, the Harris Hawk optimization (HHO) technique is based on a bionic intelligent optimum tuning approach. Gains in FOPID efficiency may be maximized by eliminating absolute error in integral time (IATE), or fitness function. MATLAB/SIMULINK is used to double-check the findings, which the findings of a comparison between the suggested HHO-based optimum AVR design and a previously published GBO-based optimal design of AVR demonstrate that the former delivers the superior dynamic response and increased stability.
