“…Based on the definition of PIO, it can be designed as follows: truextruê̇goodbreak=Atruex̂goodbreak+italicBugoodbreak+Kp()ygoodbreak−trueŷgoodbreak+Ki2w;$$ \dot{\hat{x}}=A\hat{x}+ Bu+{K}_p\left(y-\hat{y}\right)+{K}_{i2}w; $$ trueẇgoodbreak=Ki1()ygoodbreak−trueŷ,$$ \dot{w}={K}_{i1}\left(y-\hat{y}\right), $$ where w$$ w $$ in reality is known as the integral of the difference between actual and estimated terminal voltage ()ytrueŷ$$ \left(y-\hat{y}\right) $$, while vectors Kp$$ {K}_p $$, Ki1$$ {K}_{i1} $$, and Ki2$$ {K}_{i2} $$ are the proportional and integral gains, respectively, and instead of the gain vector L$$ L $$ of the Luenberger observer (Amir et al, 2018). The PIO is straightforward to install owing to its basic structure paired with great efficiency and accuracy when compared to other methods like KF or fuzzy logic (Rahul et al, 2017). Nevertheless, trial and error adjustment of the gains is required (Manthopoulos & Wang, 2020).…”

“…Therefore, data-driven approaches are advantageous for estimation of systems for which mathematical models are unknown, have high uncertainty, cannot be modeled by empirical equations, or are not suitable for analysis [13]. Fuzzy logic controllers [14], support vector machines (SVM) [15], genetic algorithms (GA) [16], and neural network (NN) algorithms [17] are used in black-box models. Estimation accuracy is highly dependent on the training data set and training method.…”
