Performance Comparison of Numerical Methods in a Predictive Controller for an AC–DC Power Converter

The use of model-based predictive control in power converters has substantially increased recent years. This technique always needs a discrete system model to be implemented. There are several methods obtain model; this paper, all common examined from practical point view. Their precision, simplicity, and implementation requirements analyzed establish their advantages disadvantages. From analysis, it is shown that different discretization result closed-loop converter performance. A AC–DC used show procedures total harmonic distortion. For evaluation, simulation 1 kW three-phase active rectifier was performed Matlab-Simulink.
