The Modular Multilevel Converter is a good alternative for high power, medium voltage drive applications due to its modularity and scalability. However, the control complex typically involves several highly-coupled circulating current feedback loops implemented using Single-Input Single-Output design tools. Additionally, each has many different frequency components electrical sequences increase...

At present, model predictive control (MPC) is widely used in power electronic converters. The objective function typically utilized to select the optimal voltage vector, but switching frequency not fixed or too high during selection process. Therefore, address this issue, a novel vector strategy for Vienna rectifier proposed paper. Specifically, hysteresis link introduced into finite set-model ...

Abstract Finite control set-model predictive (FCS-MPC) is employed in this paper to the operation of a three-phase grid-connected string inverter based on direct PQ scheme. The main objective achieve high-performance decoupled active and reactive powers injected grid from distributed energy resources (DER). FCS-MPC scheme instantaneously searches for applies optimum switching state that can cer...

In the neutral point clamped (NPC) three-level inverter-permanent magnet synchronous motor system, traditional model predictive current control (MPCC) uses system to traverse 27 basic voltage vectors, achieve d-q axis component and of multi-objective optimal control. Finite set predicts state change target at future moments based on a finite number switching states inverter. The principle this ...

A speed tracking control method for induction machine is shown in this paper. The consists of outer loop and inner current loop.
