This article proposes an improved line-constrained explicit model predictive control (EMPC) method for interior permanent magnet synchronous motors by utilizing the constraint processing capability of EMPC. Despite substantial advantages that EMPC provides motor drives, its memory occupancy and complex weight factor calculation make it limited in tackling only small-scale issues. To address these challenges, incorporates a variable converts area constraints conventional strategy into line...
Compressive sensing (CS) based sparse channel estimation requires optimal pilot patterns, whose corresponding matrices should have small mutual coherences, so as to efficiently exploit the inherent sparsity. For purpose of minimizing coherence matrix, we introduce a new distribution algorithm (EDA) optimize pattern improve performance. The proposed scheme guides optimization process by building and sampling probability model promising indexes, approaches iteratively. is able not only...
The as-built 17-4PH steel manufactured by powder bed fusion (PBF) generally requires solution and aging post heat treatments to improve performance meet service requirements. This is because the Cu-rich phase in microstructure has no time precipitate grow due high cooling rate of PBF process. For first time, this study proposes using inherent treatment environment realize in-situ optimization specimen, thus avoiding expensive post-treatment costs. Tensile tests were conducted on specimens...
In search of next-generation solar cells, silicon nanowire arrays have attracted great attention since they are costeffective and may absorb more light compared to thin-film cells. Theoretical studies using finite-different time-domain transfer matrix methods been performed investigate the optical properties (SiNW) arrays, however, computationally intensive require periodic condition, which not be satisfied with most fabricated samples. present study, an effective medium analysis is study...
This paper proposes an improved line-constrained Explicit Model Predictive (EMPC) single q-Axis current reference control strategy for surface-mounted permanent magnet synchronous motors (SPMSMs). The traditional EMPC algorithm is challenging to run on low-cost devices due its high memory consumption. adopts the of directly constrain d-axis 0A, eliminating need information about in state variables. Compared algorithm, further reduces model dimensions. In this way, usage and execution time...
This paper proposed a new control method which combines the explicit model predictive (EMPC) with field weakening strategy, and linearization approach corresponding to interior permanent magnet synchronous motor (IPMSM) mathematical is established. In order employ robustness dynamics of system, parameter tuning based on closed-loop pole analysis its experimental results are given. The upon has been verified by simulation results.
