Model predictive current control with a finite set of novel voltages and modulator in permanent magnet synchronous motor drives

Finite control set model predictive (FCS–MPC) has been deployed extensively in electric motor drives and power electronics applications. Many advantages, including fast transient response, have reported. However, the improvement of its steady-state performance, that is, suppression current ripple, is one main problems a conventional FCS–MPC strategy. This article presents strategy based on using concept variable voltage smoothing. In proposed method, finite novel vectors, produced by smoothing process, are introduced as candidate input candidates, controller generates optimum output modulator integrated with scheme. Thus, candidates generated flexibly, suitable for acceptable performance determined input. addition, smoothness can be updated automatically depending drive situation, transient, or operation, thus avoiding degradation dynamic performance. Simulation experimental results obtained permanent magnet synchronous system demonstrate effective to achieve tracking while suppressing ripple.
