Adaptive Neural Network-Based Virtual Flux Estimation for Sensorless Deadbeat Control of Grid-Connected Modular Multilevel Converters
This paper presents a grid-voltage-sensorless control scheme for a grid-connected modular multilevel converter based on an adaptive-linear-neuron quadrature signal generator for virtual-flux estimation (VF-ADALINE-QSG). The proposed estimator identifies the DC offset component and extracts the in-phase and quadrature f...
