The wide range of applications of underwater vehicles might motivate researchers to study control system design problems for autonomous underwater vehicles. Model predictive control is a well-known control methodology in which a performance index over a finite future is optimized and its performance index has moving initial and terminal times. This paper examines the stabilization problem of unsteady motion of underwater vehicle dynamics. The paper aims to propose a stabilization method based on model predictive control for rotational nonlinear dynamics of underwater vehicles. This paper provides a numerical solution method based on so-called C/GMRES algorithm to solve the model predictive control problem for stabilization of underwater vehicle nonlinear dynamics. The usefulness of the proposed method is verified by the results of numerical simulations.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116705758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system includes two models. First, the surface roughness prediction model is built by adopting a backpropagation neural network (NN). The model inputs include 3 cutting parameters, the inclined surface angle, and the characteristics of the acceleration for the spindle, while the output is the surface roughness. 0° and 30° machining inclination angles are considered. The backpropagation NN is also utilized for the feed rate modulation model. The model inputs include 3 cutting parameters, the error between the targeted and real surface roughness (i.e., ΔRa), and the inclined surface angle, and the output is the modulating value of the feed rate. Finally, some case study is conducted to show that the proposed NN feed rate modulation strategy can provide a more suitable feed rate to realize demanded surface roughness in inclined surface machining.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116248505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Boumaiza","doi":"10.1109/ICMT56556.2022.9997618","DOIUrl":"https://doi.org/10.1109/ICMT56556.2022.9997618","url":null,"abstract":"In order to accommodate the growing amounts of integrated renewable production, including wind and solar PV, energy networks are undergoing significant adjustments. In recent years, the growth of renewable energy sources (RES) has been greatly accelerated thanks to the privatization and deregulation of the energy industry, as well as financial incentives and energy policy measures. As decentralized energy generation is developed through residential and commercial PV applications, a new position described as an energy prosumer is produced. The traditional division between energy users and producers is eliminated as a result. Blockchain technology automate direct energy transactions inside a distributed system architecture based on consensus-based verification and cryptographic hashing, providing utilities, prosumers, and consumers with a one-of-a-kind, cost-effective, and secure energy-trading system. The objective of this project is to implement a general ABM simulation framework for energy exchange and demonstrate the operation of any blockchain process as well as the expected power profiles of homes. A robust multi-agent structure was constructed and simulated for a Transactive Energy (TE) type Distributed Energy Resources (DER) within the ECCH microgrid that is dependent on blockchain engineering. Auction systems are used in recent blockchain-based LEM plans to balance supply and demand in the future. These blockchain-based LEMs rely on accurate short-term forecasts of the energy generation and consumption of particular homes as a consequence. Such accurate estimations are usually only assumed. In the present study, this assumption was tested by first evaluating the forecast accuracy that can be obtained for particular families using state-of-the-art energy forecasting methods, and then by examining the effects of prediction mistakes on market outcomes in three alternative supply scenarios. The evaluation showed that an LSTM model may provide rather little predicting errors. The prediction process will be modified to fit the design of a blockchain-based LEM. Because of this, the current study differs greatly from past investigations that make a thorough effort to predict the time sequence of smart meters generally.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129649538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a single-phase VSM with a single-phase park transform unit (SPPTU). the SPPTU can perform park transformation on the single-phase current and voltage signals to obtain the dq components of the current and voltage signals and offer a dq coordinate system for the single-phase VSM algorithm. The results after the calculations of the electromagnetic torque Te, active power P and reactive power Q in VSM algorithm based on this dq coordinate system do not have the second harmonic component. Thence, the algorithm in the single-phase VSM with SPPTU can delete the second harmonic filter compared to the old algorithm of single-phase VSM without SPPTU, and improve the control accuracy furthermore. The single-phase VSM is based on paper [5] introduced in Section I with improvements, so it also includes fast current loop proposed by the paper. We present the performance of the novel features of single-phase VSM through a series of simulations. In addition, we also present the design of the current controller. The results show that the single-phase VSM leads to a performance as good as the VSM from [5] in terms of output active power oscillations and stability.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126325117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The robot test bench is built with four arms driven by four AC servo motors that perform torque control mode. Four motors work together to control the trajectory tracking moving platform and create a closed kinematic chain structure. Therefore, the problem of synchronous control between the arms is a challenge. To solve this problem, the synchronous Proportional-Integral-Derivative (SPID) controller is proposed based on the Proportional-Integral-Derivative (PID) controller to improve the quality of the system. The cross-coupling error of the synchronization algorithm provides the motion information of itself and adjacent joints. The synchronous controller drives both of the synchronous error and the tracking error of the system simultaneously to zero. The results of the experiment on the 4-DOF parallel robot model are compared with conventional PID controllers to demonstrate the efficiency.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130001807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vehicle can lose its controllability during critical maneuvers and conflicting environmental conditions. Hence, to improve the stability of an EV having multiple motors, torque vectoring becomes very essential. This paper aims to develop a torque vectoring control scheme based on Nonlinear Model Predictive Control (NMPC) for four-wheel drive (4WD) EVs (using in-wheel motors). This control scheme, while considering constraints, ensures the vehicle stability by achieving objectives such as tracking desired yaw rate, total torque demand and minimizing the rate of change of consecutive torque inputs. In addition, to minimize the computational effort of the NMPC when dealing with this kind of complex systems, a simple control-oriented model has been built and implemented within the NMPC to enhance the desired objectives. Simulations using a physical vehicle model have been carried out to evaluate the effectiveness of the proposed control approach.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127621836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
