For high-power converters, the low switching frequency (SF) modulation represented by selective harmonic elimination pulse width (SHE-PWM) is crucial to reduce loss and enhance efficiency with a good steady-state performance. However, since advantages of SHE-PWM mainly come from fixed angle distribution limited non-linear equations, angles should be adjusted slowly. This requires that bandwidth...

Grid faults are found to be one of the major issues in renewable energy systems, particularly wind conversion systems (WECS) connected grid via back-to-back (BTB) converters. Under such faulty conditions, system requires an effective regulation active (P) and reactive (Q) power accomplish low voltage ride through (LVRT) operation accordance with codes. In this paper, improved finite-control-set...

This paper proposes an MPC - based (model predictive control) scheme to control active and reactive powers of DERs (distributed energy resources) in a grid - connected mode (either through a bus with its associated loads as a PCC (point of common coupling) or an MG (micro - grid)). DER may be a DG (distributed generation) or an ESS (energy storage system). In the proposed scheme, the set - poin...

typical production objectives in distillation process require the delivery of products whose compositions meet certain specifications. the distillation control system, therefore, must hold product compositions as near the set points as possible in faces of upset. in this project, inferential model predictive control, that utilizes an artificial neural network estimator and model predictive cont...

In the past years, finite-set model predictive control (FS-MPC) has received a lot of attention in power electronics field. Due to very simple inclusion objectives and straightforward design, it been adopted different converter topologies. However, computational burden often imposes limitations implementation if multistep predictions are deployed or/and multilevel converters with many possible ...

An effective finite control set model predictive (FCS-MPC) is introduced for single-phase three-level T-type rectifiers supplying resistive as well constant power loads (CPL). The main problem of CPL the negative resistance phenomenon that endangers rectifier's stability. Hence, proposed FCS-MPC method based on Lyapunov's stability theory such rectifier guaranteed under all operating points. Un...
