Quality has become a very important part of the production process, as well as for the company PT Siemens Indonesia. Modern advances and developments change the consumer's perspective in choosing a desired product. Improvement and improvement of product quality in the hope of achieving a product defect rate close to zero defects. The strategy that can guarantee quality is a strategy that is able to maintain process stability, so that the process can be controlled with the aim of minimizing defective products in this final project, the background of the problem is the high voltage panel data, where there are still many panel products that are not suitable. Then from these problems, identification of the types of defective products that often occur, the factors that cause the defective products along with the proposed improvements using the define, measure, analyze, improve, control (DMAIC) method with the aim of reducing and preventing these defects. [1]. The results of identifying the types of defects that often occur show that component shortage is the highest contributor to the data with a percentage of 35%. Therefore, improvements are needed to the problem, namely conducting daily briefings and checking materials regularly, more intensive supervision so that material planning and procurement are still well fulfilled. © 2023 IEEE.

The influence of the end clamping plates on the induction machine performance is generally ignored in the initial design stage, resulting in the inaccurate calculation of the machine torque, loss and power factor. In this paper, a novel calculation method of end leakage inductances is proposed based on the frozen permeability approach. Considering the influence of the end clamping plates, the main performances of the induction machine are estimated and discussed. Moreover, according to the results from 3D finite element analysis, an improved equivalent circuit is proposed and compared with the traditional one taking the end region structures into account. © 2023 IEEE.

The manufacturing domain relies on Digital Twins (DTs) to mirror physical systems digitally, facilitating simulation, monitoring, and optimization. However, existing DTs may fail to capture the rich contextual knowledge essential for decision-making in complex manufacturing processes. The evolution to knowledge-enhanced DTs is essential, as it integrates domain-specific knowledge models, enabling a profound understanding of processes. To address this gap, this research introduces a knowledge-enhanced DT framework for the production process. This framework utilizes the ontology-based approach to aid the knowledge integration with the manufacturing DTs. The designed framework consists of three essential layers: The source layer, the Streaming data and knowledge coupling layer, and the Service layer. The proposed framework was further implemented in a lab-scale manufacturing setting and validated through several tests. The results demonstrated the seamless integration of knowledge and streaming data in the production process. © 2024 IEEE.

In the Robotic Palletizer System there is a subsystem, namely the Automatic Mobile Sheet Layer Inserter. This sub-system functions to place sheets in the form of thick cardboard on each layer of the box. The main driving components of the Automatic Mobile Sheet Layer Inserter are 2 single phase induction motor units which are controlled using an inverter and receive commands from the PLC as the main controller. The induction motor acts as a driver for the Arm Lifter and Gantry Arm. During the running process, the Arm Lifter motor experienced a problem, namely that the motor had an unstable speed, namely around 1413 RPM to 1467 RPM, the motor start time was relatively long, namely 6.25 seconds, and there was vibration in the arm lifter so that it could affect the time when placing the sheet. on each layer box. By using SVCU (Sensorless Vector control) mode on the inverter and setting parameters using the PID controller, the motor can go fast at the start, namely 4.8 seconds, has a stable speed of around 1503 RPM - 1509 RPM, and has minimal vibration. © 2023 IEEE.

The application of Particle Swarm Optimization (PSO) tuning for Artificial Neural Networks (ANNs) is an effective method for maximizing power output from photovoltaic (PV) panels in a DC microgrid system under changing irradiance conditions. This technique can be used to optimize the performance of a PV system, particularly in locations with variable weather conditions. This study proposes a new approach of implementing ANN that is tuned using practical swarm optimization technique. The ANN is trained using data generated by MATLAB Software on the weather conditions and the power output of the PV system and the PSO algorithm is then used to tune the parameters of the ANN model. The optimized ANN model can then be under severe proposed changes in irradiance and to adjust the power converter to achieve the maximum power output. The DC microgrid system used in this study is composed of multiple PV panels and battery along with a super capacitor for a storage system to feed a resistive load. The results of this study illustrate that the PSO tuning of ANNs is an effective method for maximizing power output from PV panels in a DC microgrid system under changing irradiance conditions reaching a precision of 99.7% from the PV panels and response time of 0.11s. © 2023 IEEE.

This article utilizes the flatness property of the nonlinear model of the continuous stirred tank reactor (CSTR) to design a Flatness-Based Trajectory-Tracking control (FBTTC). Focusing on the Single input single output (SISO) case, first principles of mass and temperature balance of the reactor are used in the modeling and control design. The flatness-spaces modeling task is carried out assuming two cases of selected flat outputs along with a finite number of their time derivative. The reactor temperature and the concentration are selected as flat output in each case separately. For trajectory tracking control problem, both differential flatness-based control and Feedback Linearization-Based control (FBLBC) are derived and simulated, enabling a comparison between the two methods. The chosen approach emphasizes the simplicity and high accuracy of control design using flatness property for the examined nonlinear system. © 2024 IEEE.

This paper proposes an optimal electric load forecasting technique by applying several activation functions and optimization methods in the internal structure of the Long Short-Term Memory (LSTM) algorithm to forecast mid-term electric load in Korea. As the activation function, the rectified linear unit (ReLU) and hyperbolic tangent (Tanh) are used. Optimization methods such as stochastic gradient descent (SGD) and adaptive moment optimization (Adam) are compared in the paper. In the input data, daily peak load over past seven days, maximum and minimum temperatures are used. In order to increase the efficiency of learning, special weeks and special day load data are replaced. The proposed method shows stable and great performance with small average errors, compared to the RANN based forecasting method which is a previous study. Especially, the estimated error is improved in the summer and winter where the temperature changes significantly. Copyright © 2022 The Korean Institute of electrical Engineers.

Effective control Strategy for Energy Storage System based on Measuring Rate of Change of Frequency

引用

Transactions of the Korean Institute of electrical Engineers 2022年第10期71卷 1351-1357页

The paper describes an effective control strategy for energy storage system (ESS) according to the severity of occurring in power system. ESS is generally used to mitigate the frequency oscillation against the power system disturbances. However, ESS can frequently operate even in situation where it is not necessary to operate due to small load change or small fluctuations in renewable energy. It can cause the frequency variations of the state of charge (SOC) of ESS and shorten the lifespan of the ESS. Therefore, the paper proposes effective control method to reduce the unnecessary operation of ESS by categorizing three control modes based on measured rate of change of frequency (ROCOF). The performance of the proposed method is verified through time domain simulation by applying it to the microgrid system. © 2022 Korean Institute of electrical Engineers. All rights reserved.

Feedback-based methods combining proportional-integral and/or resonant controllers are the most common option for Active Power Filter (APF) control. Alternatively to classical feedback-based control, state-feedback current control could be used, potentially enabling better dynamic performance. State-feedback current control has been previously proposed for grid-connected converters;however, reference tracking response of multiple harmonic components of the controlled current has not been reported. This is highly relevant to comply with grid codes. This paper analyses the design and implementation of state-feedback current control for harmonic current compensation in APFs. © 2024 IEEE.

This paper proposes a H∞ control scheme for the multiphase permanent magnet synchronous motor (PMSM). The H∞ scheme is designed through frequency domain indicators to significantly enhance the dynamic performance of the system and reduce its sensitivity to parameter perturbations. The comparison between the proposed control method and the traditional PI controller were conducted on a dual three-phase PMSM simulation. The results demonstrate that the proposed method has a faster dynamic and greater robustness, validating its effectiveness over the conventional approach. © 2024 The Institute of electrical Engineers of Japan.
