It has been accepted that the new network architecture needs to separate the locator from its identifier. Identifier is used to present the information source and information sink while the locator is used for routing. It is necessary to use replacement, not encapsulation,...
Predictive current controller is often adopted to compensate time delays caused by digital control. But traditional predictive current control algorithm for four-quadrant converters is an open-loop current observer essentially. Current value predicted is affected by many factors such as grid voltage extrapolation error, inductance error and dead-zone time. All of them will aggravate the grid current...
