This paper presents an on-off controller for a simple motor (UM) with a PWM chopper. Standard pace operation is required during various programs of universal motors, regardless of the ton variants. The controller is designed to run in a washing machine program that uses the spin method and needs a continuous velocity of 12000rpm. A two-pole, 230V, 450W Universal engine with a minimum velocity of 400 rpm is used in this effort. To obtain the reference speed, the motor terminal voltage is controlled. The input AC source voltage is rectified in the proposed management process, and the resulting DC voltage is chopped using an IGBT to control the voltage across the engine. For frequency calculation, a sixteen-pole tacho generator is connected to the engine shaft. A PIC 16F877A microcontroller is used to implement closed-loop regulation, which provides the switch gate heartbeat by comparing the real speed to the reference velocity. The MCT2EM optocoupler is used to achieve isolation. As compared to other management circuits, the PWM-based management circuit produces fewer harmonics, present ripple, and torque ripple. The advanced system is a simple speed controller with improved system output at a low cost. By adding a current control loop, the overall software output can be improved.

This research paper addresses a robust tilt PID controller for stabilizing frequency of an AC Microgrid under various functional conditions. The proposed tilt PID controller is structured in optimum by employing a novel harmony search algorithm (HSA). Microgrids are structured with integration of different micro sources like micro-turbine, small diesel generator, fuel cell, wind generator, solar photo voltaic (PV) cells etc. It has been verified that most of micro sources are renewable energy based and also possesses large dynamics and low inertia. The unpredictable large dynamics of wind generator and PV cell creates instability issues in the Microgrid system. On other hand these inertia less generating units are unable to capture sudden load change hence a serious frequency instability occurs in the Microrid system. In order to pertain stability over system frequency a high control action is required under various disturbances. Apart from load deviation, wind fluctuation and solar intensity variations are the main disturbances in the Microgrid system to cause frequency oscillation. So this article has proposed a novel HSA designed tilt PID controller for frequency control of an AC Microgrid under different uncertainties.

Trigate FinFETs are the most promising solutions to short channel effects in the sub 50 nm technology nodes. The analog and RF performance of these devices is an important concern and these depend on the device geometrical parameters. In this paper, we have studied the effect of FinFET geometry parameters (channel length and fin height) on the RF figure of merits by using TCAD simulations. The variation in the cutoff frequency fT, maximum frequency of oscillation fmax and gain bandwidth product (GBW) with the change in gate length and fin height are shown. We found improvement in the RF parameters by decreasing the channel length or increasing the fin height.

Microgrid(MG) provides numerous advantages such as reduced transmission losses, low carbon emission, improved system reliability. However, for the proper functioning of the MG, it should be protected from different fault conditions. Detection of fault conditions in MGs is challenging because the fault current magnitude varies in various modes of microgrid operations, types of DGs used, ratings of DGs, and bidirectional fault current flow. This article presents a signal processing-based technique to determine the faults in the Microgrids and state-of-the-art latest research on microgrid fault detection. This paper analyzes different phasor estimation techniques such as sample to sample comparison (S to S) technique, cycle to cycle (C to C) comparison, and Kalman filtering technique for Microgrid fault detection. The microgrid with various types of DGs are simulated using RTDS/RSCAD (Real-time digital simulator), and the Kalman filtering techniques can effectively detect different fault conditions in the microgrid.
微电网具有降低输电损耗、低碳排放、提高系统可靠性等诸多优点。然而，为了使磁力发电机正常工作，需要对其进行不同故障条件下的保护。由于微电网运行的不同模式、所使用的dg类型、dg的额定值以及双向故障电流的不同，故障电流的大小也各不相同，因此MGs故障状态的检测具有挑战性。本文介绍了一种基于信号处理的微电网故障诊断技术，以及微电网故障检测的最新研究进展。本文分析了不同的相量估计技术，如样本间比较(S to S)技术、周期间比较(C to C)技术以及用于微电网故障检测的卡尔曼滤波技术。采用RTDS/RSCAD (Real-time digital simulator，实时数字模拟器)对不同类型dg的微电网进行了仿真，卡尔曼滤波技术可以有效地检测微电网中不同的故障状态。

To enhance the output efficiency of the photovoltaic (PV) arrays, it is indispensable to track the maximum power point (MPP) to extract maximum power in the energy conversion process. However, this has become a challenging issue in the past many years due to the nonlinear characteristics of the PV cell and the adverse impact of temperature variation, irradiance change, partial shading, dust, and aging effect on the output generation. In maximum power point tracking (MPPT), the duty cycle of the DC-DC converter is adjusted in a way that the maximum possible power is extracted from the PV system. This paper has two major objectives to present as a brief review of the methods suggested in recent times and comparing the two classical techniques Perturb & Observe (P&O) and Incremental Conductance (IC) technique used most in real-time applications. A discussion on possible challenges and issues has been entailed at the end to serve as a vital reference to guide the system engineers to develop better techniques for MPPT control in the future.

This article examines ideal shaking covering of a cantilever column using gathered piezoelectric patch units. A rectangular aluminum salver demonstrated fit as a fiddle with one set of piezoelectric patches as transducer has been utilized to explore the viable trembling regulator. A state space model to reproduce reaction interval methods with a pillar mounted piezoelectric transducer sets is created. Absolute coordinated work done in the framework is limited by shifting situation of piezoelectric transducer sets having consistent dimension whereas maintaining criticism acquires steady. COMSOL Multiphysics 5.4 variant programming is utilized to determine the limited component plate framework. As indicated by framework, areas of optimum sensitivity are identified and positive pillar is molded. A suitable recreation control methodology has been explored through MATLAB programming by which the addition of the regulator has been advanced to accomplish proficient dynamic trembling concealment with least control input.

In this paper, a group III-V channel material In0.53Ga0.47As/InP based hetero dielectric trench-gate (HD-TG) power MOSFET (HD-TG-MOSFET) is presented for low voltage application. This model is employing band-to-band tunneling phenomena at the interface of n- In0.53Ga0.47As drift region and n+InP drain region. The proposed device contains a trench within both sides of the source of In0.53Ga0.47As body and n-In0.53Ga0.47As drift region which makes the parallel conduction of the channel from the source to drain. So, there is a reduction of surface field effect in the channel which improves the other device performance parameter. HD-TG-MOSFET offers low Ron and improved transconductance due to the use of high mobility material In0.53Ga0.47As in the channel region. From the 2D TCAD device simulation, it is demonstrated that the proposed device shows improved device performance in terms of On-resistance, peak trans-conductance, and drain current which is suitable for high speed and low power applications as compared to the conventional trench gate (C-TG) power MOSFET.

During the spread of the Corona epidemic, everyone started wearing masks as protection in public places. Therefore, this causes a major challenge in authentication and safety systems, such as face recognition systems in railway stations, airports, and payment systems based on facial recognition technologies. Face recognition systems are safer than touch-based biometric systems. However, the face recognition systems are ineffective in the presence of a face with a mask. Therefore, we developed an efficient algorithm using the MTCNN and VGGF model to improve the efficacy of face recognition systems in partially occluded face images. The proposed approach produced 90% accuracy in the top half of the facial images.

The Utilities and the users of electricity are very much perturbed about the quality of power. Since the 1980s the word power quality is becoming one of the most copious terms in the particular industry. Mainly, power quality involves different issues like sag, swell, power factor variation, power pollution due to harmonics and lots more. The uses of power electronic loads (non-linear loads) are the main cause of such issues. Here power factor variation one of the main power quality issues is being considered which rises in a PV grid connected system. To check variations in power factor fuzzy logic control is implemented with a DC-DC boost converter. The power factor is calculated for 3 phase and simulation was carried out using MATLAB/SIMULINK. The outputs were studied and the results were verified.
