Simulation studies of three synchronous reluctance motor (SynRM) control strategies are presented: field-oriented (FOC), direct torque (DTC), and finite-set model-predictive (FS-MPC). FOC uses linear controllers pulse-width modulation to the fundamental components load voltages vectors. In contrast, DTC FS-MPC nonlinear wherein voltage vectors directly generated in absence a modulator. Theoreti...

AbstrakBakteri endofit yang terdapat di tanaman pisang Klutuk dan keterkaitannya dengan sifat ketahanan pada cekaman biotik abiotik belum dilaporkan dalam publikasi ilmiah. Sebanyak 93 isolat bakteri telah diperoleh dari Klutuk, tetapi diketahui kemampuannya sebagai pendukung pertumbuhan (PPT). Penelitian ini bertujuan untuk mengetahui karakter isolat-isolat tanaman. Kelompok Gram positif negat...

Particle Swarm Optimization (PSO) has potential applications in electric drives. The excellent characteristics of PSO may be successfully used to optimize the performance of electric machines in many aspects. In this chapter, a field-oriented controller that is based on Particle Swarm Optimization is presented. In this system, the speed control of two asymmetrical windings induction motor is ac...

We present two new high-precision physics-based radiation force models for the In-Orbit Validation (IOV) and Full Operational Capability (FOC) spacecraft (s/c) of Galileo Global Navigation Satellite System (GNSS). In both cases, s/c bus surfaces are covered in material types, i.e., Laser Retro-reflector Array (LRA), Optical Surface Reflector (OSR) Single-Layer Insulation (SLI) coverings, that w...

During the last years, different methods for identifying permanent magnet synchronous motor (PMSM) parameters have been developed. Such allow a better characterization of PMSMs, thus enabling control. This article presents novel PMSM parameter estimation method based on differential power factor due to harmonic distortion, which allows identification from data acquisitions representing entire t...

The effectiveness of a permanent magnet synchronous motor (PMSM) drive managed by an automatic voltage regulator (AVR) microcontroller using field oriented control (FOC) with space vector modulation (SVM) and diode clamped multilevel inverter (DCMLI) is investigated. Due to its efficacy, FOC would be widely implemented for PMSM speed regulation. primary drawbacks 3-phase classic bridge appear r...

A Caputo-type fractional-order mathematical model for "metapopulation cholera transmission" was recently proposed in [Chaos Solitons Fractals 117 (2018), 37--49]. sensitivity analysis of that is done here to show the accuracy relevance parameter estimation. Then, a fractional optimal control (FOC) problem formulated and numerically solved. cost-effectiveness performed assess studied measures. M...

Electric vehicles are regarded as a significant way to mitigate the global energy crisis and environmental pollution problem. Motor control is very important part for electric vehicles. As hardware, motor controller usually has components such power module, microprocessor unit, IGBT driver, sensors, resolver-to-digital convertor. software, field-oriented (FOC) with space vector pulse width modu...
