“…So simple nonlinear methods become attractive alternatives for complex system applications where high reliability is required. Due to these characteristics, the application of the SC has been extended from simple systems such as electric motors to systems for generating electricity from renewable energy sources [19], [20], [21], [22]. These works demonstrated the efficiency and performance of the SC strategy in improving the characteristics of several systems and strategies, such as overcoming the problems and defects of both PI and DPC.…”

This work provides regulation of active and reactive power for asynchronous generator-based multi-rotor wind power (MRWP) systems using a synergetic control based on fractional order control theory. The traditional synergetic control theory achieves an undesirable chattering effect, which can damage the system. For this, it is relevant to combine the traditional synergetic control theory with fractional order control to avoid these drawbacks. Two control schemes are proposed, analyzed, and compared: traditional direct power control (DPC) and DPC based on fractional-order synergetic controllers, the latter needs only the information of the sliding surface. Their characteristics are compared in terms of current quality, active and reactive power reference tracking, robustness against generator parameter variations, and power ripple. Simulation results using Matlab software have demonstrated the characteristics and robustness of the

For the surface‐mounted permanent magnet synchronous motor (SMPMSM) drive system, a fast terminal synergetic speed control (FTSSC) is proposed to improve its speed dynamic performance and robustness. In the proposed control scheme, the ultra‐local model of SMPMSM drive system, which considers motor parameter uncertainties and unknown disturbances, is set up based on the algebraic parameter identification method. Then, the nonlinear terminal manifold is designed to achieve speed rapid convergence in finite time, moreover, the fast synergetic speed control law that satisfies the voltage and current constraints of SMPMSM drive system is derived. Meanwhile, the Lyapunov function is designed to prove the stability of the proposed fast terminal synergetic speed‐controlled SMPMSM drive system. Finally, the effectiveness and feasibility of proposed control is verified through the experimental research of SMPMSM drive system. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.

In recent years, grid-connected multifunctional photovoltaic (PV) systems have proven to be highly efficient. This system integrates PV panels with a DC–DC boost converter (DC–DC–BC) and the electrical distribution grid (DEG). Linking the PV to the AC-DEG is accomplished through a three-level multifunctional voltage source inverter (MVSI). The DC–DC–BC component in this study is engineered to perform maximum power point tracking (MPPT) irrespective of normal or abnormal conditions. The conventional MPPT technique poses several challenges and constraints on system usage. Hence, the suggestion is to adopt synergetic control (SC) and sliding mode control (SMC) to enhance the MPPT technique's performance within the proposed system framework. Moreover, predictive direct power control is applied to the MVSI-based shunt active power filter, utilizing a phase-locked loop technique to achieve multiple objectives: minimizing energy fluctuations, injecting active power, correcting power factors, compensating reactive power, and mitigating harmonic currents. To implement the proposed system, the MATLAB is used for this purpose, with several tests used to study the behavior of the controls proposed in this work. Numerical results indicate significant reductions in active and reactive power fluctuations, with estimated rates of 38.46% and 15.30%, respectively, compared to traditional strategies. Moreover, the total harmonic distortion (THD) of the source current after filtering is reduced by 31.88% under solar irradiation of G = 1000 Wm 2 . Before filtering, the THD of current experiences a reduction estimated at 97.65%. These findings underscore the superior performance of the proposed control technique across all evaluated aspects.
