This paper introduces an improved virtual synchronous machine (i-VSM) control concept using state-of-charge (SOC) voltage feedback as a key parameter to generate a virtual flux model within the fast-charging station (FCS) based rectifier converter. The i-VSM was modelled using VSM reactive power loop and the SOC-driven charging voltage as a reference input to the VSM. Through this approach, the i-VSM adjusts the virtual 's field excitation to produces the electromagnetic force fed to the pulse generator, which generates the switching signals to control the rectifier converter output to match grid response deviation during FCS operation. The i-VSM model was tested across 150 kW and 300 kW -rated multiple FCS setups. The comparison of the i-VSM with a conventional VSM-PI controller-based FCS, demonstrated the i-VSM's superior performance in accurately maintaining a steady power response flow, voltage tracking and frequency regulation at the rated values at PCC. The detailed voltage output variable response, stability analysis (Bode diagram) and current total harmonic distortion comparison are included in this paper.

However, despite these qualities, it is often confronted with torque ripples and harmonic currents that limit its operational efficiency. To overcome these challenges and improve the global control of the drive system, this paper proposes a novel study to improve the performance of DTC for DSIM based on a set of three techniques. Firstly, by appropriately selecting two voltage vectors at each sampling period, the impact of current harmonics is considerably reduced, but torque and flux ripples remain significant. Secondly, the method above is combined with a switching table featuring three virtual voltage groups, significantly reducing torque ripples and harmonic losses. Finally, an intelligent control based on artificial neural networks (ANNs) will replace the speed regulator, the above switching table, the two-level hysteresis flux regulator, and the seven-level hysteresis torque regulator to select an optimal virtual voltage vector. The performance of the final technique shows the following advantages: further reduction of torque and stator flux ripples, less overshoot in speed and torque, and almost complete suppression of harmonic currents.

While SDMvi models are fundamental for PV system analysis and design, this assumption may limit prediction accuracy, particularly when dealing with nonlinear and dynamic PV characteristics. This paper introduces an enhanced single-diode model (SDMvd) that accounts for the voltage dependence of its five parameters. To achieve this, two new variables, P1 and P2, are introduced to segment the I-V curve into three regions, each containing the three characteristic points: maximum power point (MPP), open-circuit voltage (Voc), and short-circuit current (Isc).

However, controlling these systems is challenging due to their nonlinear dynamics, unpredictable disturbances, parameter uncertainties, and rapid wind speed fluctuations. To address these challenges, robust control strategies are essential. This study presents a novel robust nonlinear controller for regulating the electromagnetic torque of horizontal-axis, variable-speed WPGSs with three blades connected to the grid. The proposed controller is designed to enhance system efficiency and profitability by maximizing electricity production, reducing torque ripples, eliminating peak overshoots, and achieving precise setpoint tracking with optimal transient performance. The controller combines sliding mode (SM) control with fractional calculus (FC) to exploit the benefits of both methods. SM control, known for its effectiveness in controlling nonlinear systems, stabilizes the system and ensures finite-time convergence to the desired state. The incorporation of fractional-order operators into the sliding surface introduces greater flexibility, leveraging the long-term memory properties of FC to enhance system stability and robustness while mitigating chattering effects.
