“…To improve the performance of the conventional PSSs, many approaches for tuning the parameters have been proposed such as classical methods, variable structure and adaptive control method (Ghany and Shamseldin, 2020), intelligent control methods (Baadji et al, 2019), robust control method (Sharma and Mishra, 2018) and gradient methods for optimization (Guo et al, 2019). However, designing a PSS system is a difficult assignment because it involves a heavy volume of system modeling and a substantial optimization computational time on the system (Ibrahim et al, 2019; Setiadi et al, 2019). Other PSS design procedures employed in the literatures are optimal control technique, (Yousefian et al, 2017), adaptive control approach, (Kulkarni et al, 2015), numerical programming method (Naghshbandy and Faraji, 2019), robust control method (Zhou et al, 2018), H ∞ technique and eigenvalue method (Gomes et al, 2018) and so forth.…”
