Based on the experiential avoidance (EA) model, we explored the impact of fear of COVID-19 (FOC) on adolescents’ mobile phone addiction (MPA) as well as the sequential mediating effect of depression and EA. We recruited a sample of 1,132 middle school students; they filled out the Fear of COVID-19 Scale,...

This paper proposes a parallelization method for meta-heuristic particle swarm optimization algorithm to obtain a convincingly fast execution and stable global solution result. Applied the proposed method, the searching region is efficiently separated into sub-regions which are simultaneously searched...

The paper introduces the field oriented control (FOC) and voltage space vector pulse wide modulation (SVPWM) arithmetic, develops a suit of Digital Vector Controlled frequency -variable speed-adjustable system based on digital signal processor (DSP) TMS320LF2407 of TI company, and research and analyze...

In isolated and linked power systems, load frequency control (LFC) is critical in delivering high-quality power. The LFC must be resilient to the system's parameter uncertainties and have a strong disturbance elimination capacity to maintain high-quality power. In the presence of wind Power generation...

The usage of Fractional Order (FO) controllers for an electrical vehicle system is examined in this research (EVS). The auxiliary batteries, controller, charging port, onboard charger, electric motor, power in veelectriction battery pack, DC-DC converter, transmission, and thermal cooling system are...

The current technology for PMSM (Permanent Magnet Synchronous Motor) drive controllers in electric go-karts focuses on achieving high efficiency, precise torque control, and superior performance. Modern PMSM drive controllers utilize advanced FOC techniques to ensure smooth operation and optimal speed-torque...

The zero crossing detection is essential in twelve sensors-less control using back-EMF. To increase output power of Brushless DC motor (BLDCM), traditional twelve step control has extended active angular period. It has drawback which become unstable the performance of the drive system in rated load condition...

The article discusses the significance of high-performing Permanent Magnet Synchronous Motors (PMSM) in industries such as transportation, robotics, and industrial sectors due to their small size, high efficiency, and fast responsiveness. Field Oriented Control (FOC) is used in PMSM drives to achieve...
