This work presents a dead-time compensation technique for robust predictive current control of grid-connected voltage source inverter. Among current controls, dead-beat predictive controllers are one of the fastest, but are extremely sensitive to inconsistencies between the model and the actual plant. Dead-time modifies the plant model and is one of the main sources of distortion in high dynamic range...
This paper presents a self tuning robust predictive current controller that can be applied to both single and three phase grid tie voltage source inverters. Due to its adaptive capability, this control has a great robustness to paremetric variations, presents low steady-state current error and lowers dead time distortion in contrast with its nonadaptive variant (RPCC). Both simulation and experimental...
This study presents a new software-based plug-in dead-time compensator for grid-connected pulsewidth modulated voltage-source inverters of single-stage photovoltaic (PV) systems using predictive current controllers (PCCs) to regulate phase currents. First, a nonlinear dead-time disturbance model is reviewed, which is then used for the generation of a feed-forward compensation signal that eliminates...
