Abstract
This paper proposes a current control strategy for a single-phase grid-tied inverter under conditions of parameter uncertainty and disturbance. Inductance and filter resistance deviations degrade the performance of traditional model-based control methods. To overcome this, a Radial Basis Function (RBF) neural network is used as an online observer to approximate and compensate for aggregate errors due to uncertainty and unmodeled dynamics. Simultaneously, Super-Twisting Sliding Mode Control (STSMC) is applied to reduce the chattering phenomenon and ensure finite-time convergence with a continuous control signal. The RBF–STSMC combination reduces conservatism in parameter selection and enhances system robustness. Stability is demonstrated using Lyapunov, and MATLAB/Simulink simulation results show superior performance compared to traditional SMC and PID controllers.
This study focuses on the development of robust control strategies for a photovoltaic system integrated with a grid-connected quazi-Z-source inverter (qZSI). Conventional current control methods, such as proportional–integral (PI) controllers, often fail to maintain satisfactory performance under system uncertainties....

To improve the dynamic response and disturbance rejection of the LLC resonant converter, a super-twisting sliding-mode linear active disturbance rejection control (STSM-LADRC) strategy is proposed. First, a small-signal model of the LLC resonant converter is established using the extended describing function method, an...

In PMSM sensorless control systems, conventional sliding mode observers are prone to chattering and noise during backEMF estimation, which negatively affects speed stability and estimation accuracy. To mitigate these issues, a sensorless control scheme that combines a linear super-twisting sliding mode observer with a...
