In this article, proposes an adaptive multiband hysteresis modulation and its characterization based on a robust nonlinear sliding-mode control (RNSMC) strategy of a dual two-level inverter topologies for photovoltaic (PV) system subject to robust and fast-tracking characteristics and external disturbance rejection. Using the RNSMC based novel, vector control schemes are designed and implemented to improve its robustness and against the rejection of external disturbances. The control scheme ensures the active power is stable across the whole operation of the PV systems (standalone and grid-connected). The reachability and stability analysis are obtaining the robustness of the controller. Tsypkin's method is used to realize the switching frequency characterization. The development and implementation approach of the proposed control strategy is thoroughly detailed, and its effectiveness is validated on the simulation and real-time laboratory tests. Moreover, the proposed scheme is superior in keeping the enhanced efficiency, multilevel voltage waveforms, and total harmonic distortion (THD) reduction in current within the necessary standard limitations even under different operating conditions. • A novel AMHM-RNSMC strategy is proposed for dual inverter-based PV systems. • Tsypkin's frequency domain analysis method is utilized to obtain the inverter switching frequency. • The Fast and robust dynamics and control aspects of stand-alone and grid-connected PV systems are presented. • The proposed system is compared to common benchmark systems. • Simulations and real-time experiments are done to verify the performance of the proposed controller.
