systems for distributed generation sources. In three-phase systems, using three-phase conversion
to the synchronous reference frame, linear controllers can be easily used to control the inverter due
to the conversion of AC parameters in the synchronous frame to dc components. The design of
linear controllers in single-phase systems is often difficult because of the oscillating nature of these
systems. In some cases, single-phase conversion to synchronous frame is used, which has its
problems, such as delays in converting single-phase values to two-phase. To tackle this problem,
proportional-resonance (PR) instruments can be used at a specific resonant frequency. However,
for single-phase systems where all the harmonies are present in the inverter current, an unlimited
number of PR instruments are required. Therefore, not all harmonies can be controlled in this way.
To overcome this, a iterative control system can be used. The control method presented in this paper
uses delay intervals with positive feedback. Under these conditions, the control gain in the dynamic
model of the iterative control system is very high for all harmonies and allows tracking the reference
current and voltage values with a zero steady-state error in all harmonies. In addition, the
performance of the iterative control system in the face of single-phase systems will be very
favorable.

ANF-GTA demonstrated superior performance compared to ANF-HBA, with a 50% higher performance in the learning phase and an 80% higher performance in the evaluation stage, as measured by the MedSE index values. The ANF-GTA obtained lower SMAPE index values of 5.2192 and 5.39 compared to the values of 8.0622 and 9.3783 obtained by the ANF-HBA during the learning and assessment phases, respectively.

Traditional empirical and theoretical methods for estimating USS based on field tests often rely on correlation assumptions, leading to imprecise results. These conventional strategies are also limited in terms of efficiency, both in time and cost. To address these limitations, this study introduces innovative machine learning techniques, employing the Support Vector Regression (SVR) model to accurately predict USS. To enhance model performance, three meta-heuristic optimization algorithms Differential Squirrel Search Algorithm (DSSA), Golden Section Search Optimization (GSSO), and Northern Goshawk Optimization (NGO) were utilized. The frameworks were trained using four key input metrics: plastic limit (PL), liquid limit (LL), sleeve friction (SF), and overburden weight (OBW). The performance of the proposed frameworks was evaluated using five criteria: R², RMSE, MSE, SI, and SMAPE. Among the three hybrid frameworks developed for estimating USS, the SVR optimized with the Northern Goshawk Optimization (SVNG) algorithm outperformed the others, achieving the lowest RMSE value of 39.30 in the testing step and the highest R² value of 0.9980 in the testing step. These results demonstrate the superiority of the SVNG model in providing precise and efficient predictions of USS, surpassing conventional methods.

systems for distributed generation sources. In three-phase systems, using three-phase conversion
to the synchronous reference frame, linear controllers can be easily used to control the inverter due
to the conversion of AC parameters in the synchronous frame to dc components. The design of
linear controllers in single-phase systems is often difficult because of the oscillating nature of these
systems. In some cases, single-phase conversion to synchronous frame is used, which has its
problems, such as delays in converting single-phase values to two-phase. To tackle this problem,
proportional-resonance (PR) instruments can be used at a specific resonant frequency. However,
for single-phase systems where all the harmonies are present in the inverter current, an unlimited
number of PR instruments are required. Therefore, not all harmonies can be controlled in this way.
To overcome this, a iterative control system can be used. The control method presented in this paper
uses delay intervals with positive feedback. Under these conditions, the control gain in the dynamic
model of the iterative control system is very high for all harmonies and allows tracking the reference
current and voltage values with a zero steady-state error in all harmonies. In addition, the
performance of the iterative control system in the face of single-phase systems will be very
favorable.

ANF-GTA demonstrated superior performance compared to ANF-HBA, with a 50% higher performance in the learning phase and an 80% higher performance in the evaluation stage, as measured by the MedSE index values. The ANF-GTA obtained lower SMAPE index values of 5.2192 and 5.39 compared to the values of 8.0622 and 9.3783 obtained by the ANF-HBA during the learning and assessment phases, respectively.
