The Permanent magnet synchronous motor (PMSM) drive has emerged as one of the most preferred motor drives for industrial applications. Its distinguished advantages include high torque density, high efficiency, and vast speed range operation. This paper presents, first, details of PMSM drives and their components. Second, explains the modelling of PMSM. Third, discusses the needs of position sensors, their applications, Read More

Introduction: Rural electrification in India is planned with high-capacity distribution transformers which supply the isolated location loads of various categories like agricultural, household, small business, etc. This distribution system planning with non-optimal distribution transformers leads to poor voltage profiles and high power losses in the distribution network. This paper presents that a High-Voltage Distribution System (HVD Read More

Background: With the access to large-scale distributed energy, the voltage off-limit problem of the distribution network has become more and more serious, and the traditional centralized voltage control method has been difficult to meet the demand of distribution network control and market development. Methods: In this paper, a voltage regulation strategy based on decentralized wind power clustering is proposed. C Read More

Background: Image denoising methods based on partial differential equations have attracted much attention due to their "infinite" local adaptation capabilities, high flexibility, and strong mathematical theoretical support. Methods: This paper proposes a mixed higher order partial differential equation denoising model for the step effect caused by the second-order denoising model and the edge blur caused by the fourth-order Read More

Background: With the continuous penetration of renewable energy in modern power systems, the problem of excessive frequency deviation of power systems, which is caused by the integration of wind power into electricity grids, needs to be solved urgently. Objective: Make up for frequency fluctuations when AC systems fail, improve the frequency characteristics of main system networks, and reasonably distribute Read More

Background: Reliability analysis of logic circuits has been widely investigated due to increasing fault occurrence in modern integrated circuits. Simulation-based and analytical methods are developed to estimate the reliability of logic circuits. Methods: In this paper, a signal probability-based method is presented to estimate the reliability of logic circuits. In the proposed approach, four signal probabilities (correct 0, correct 1, i Read More

Background: Accurate identification and positioning of sugarcane buds is not only the prerequisite for the automatic cutting of sugarcane buds, but also the premise of intelligent directional planting of sugarcane. Objective: In this study, a feature extraction and recognition method for sugarcane buds was proposed based on the S component in HSV model to identify the position of sugarcane bud center in the sugarcane seed ima Read More
