In this paper, a three-phase grid-connected inverter is modelled as a switched affine system with both continuous and discrete dynamics. Based on the model, a novel switching control law, which can track reference current generated by power reference and grid voltage, is proposed by using the switched Lyapunov theory and the matrix inequality technique. A main advantage of this method is that the...
In this paper, a grid-connected single-phase neutral point clamped inverter is represented by a hybrid model with both continuous and discrete dynamics. A novel state-feedback switching control law is proposed in terms of linear matrix inequalities (LMIs) which can drive the output current to track a sinusoidal reference. The main advantage of this method is that the switching states of the inverter...
In this paper, a novel output feedback control approach is proposed for DC-DC Cuk converters. To compensate the information loss due to limited access to the state, a multiple sampling scheme is employed to derive a discrete-time switched affine model with an augmented measurement output. Based on the model, an output-feedback switching control law, which drives the system state to a set of attainable...
In this paper, a novel prediction-based switching control approach is proposed for DC-DC buck converters. This approach can be implemented directly with digital devices, and no complicated modulation is involved. The buck converter is modeled as a sampled-data switched affine system. In order to avoid the delay of switching signal, a novel prediction approach is adopted. The switching law is designed...
