The identification of parameters of the permanent magnet synchronous machine (PMSM) is considered. The paper uses a discrete model of the permanent magnet synchronous machine. The proposed algorithm makes it possible to consider the errors in measurements of current, voltage, and electrical angular speed. Extended instrument variables are used to identify parameters. To solve the overdetermined system, total least squares are used. This makes it possible to improve the accuracy of estimates of extended instrumental variables on a finite sample. The simulation results confirmed the high accuracy of the resulting estimates. © 2022 IEEE.

Data-driven controller synthesis methods allow finding controller parameters based only on the system input-output response. Among these methods, Virtual Reference Feedback Tuning (VRFT) is accepted thanks to its reference-model based direct parameters synthesis, including robustness and noise rejection considerations for integer and fractional-order controller design. However, for fractional-order VRFT controller synthesis, a direct solution is harder to reach involving a complex optimization problem to solve. This paper presents a recursive VRFT method for synthesizing arbitrary degree fractional-order controllers with feedforward based on a integer or fractional-order reference model. This methodology leverages existing optimization tools for fractional-order systems identification to obtain integer and fractional-order controller gains when integer and fractional-order reference models are used for the virtual error computation. The proposed method synthesizes a set of feedforward VRFT controllers implemented to control a uniform temperature control system. The results show that combining a fractional-order model or compensator improves the energy consumption of the controller and the transient temperature response in tracking and regulation tasks.

This study aims to develop an Automatic Generation control (AGC) algorithm that enhances load-frequency control performance for multi-Area power systems taking the network splitting conditions into account. The AGC algorithm includes adaptive control capability for increasing the network Area control Error (ACE) performance and manages multiple operation states for robust real-Time frequency control operations. Basically, in case of a network splitting, the algorithm evaluates conditions of generating units and determines manageable control areas based on the sufficient reserve availability. The operation and performance of algorithm are verified during and after the splitting without an interruption via software-in-The-loop simulations. During this study, the simulation and test platform including a real time power system simulation platform, a graphical user interface, and a communication interface are built and used in order to evaluate the proposed algorithm. © 2023 IEEE.

The protection and control system in substations has undergone significant evolution since the era of hardwired systems. In recent years, the increasing trend of digital transformation (DX) across various fields, including protection and automation systems, has led to the promotion of IEC 61850 process bus-based digital substations. However, recent analysis and evaluation have revealed numerous challenges in various aspects, such as technical issues, system performance, test methods, maintenance, and economic considerations. Moreover, many of these challenges lie outside the scope of international standards like IEC 61850 and IEC 61869. As a result, the worldwide implementation of digital substations has been hindered. This paper aims to describe the issues encountered during the implementation of process bus technology and propose solutions that focus on optimizing system configuration based on our experience in implementing digital substation projects and developing MU and IED. Addressing these issues is crucial to fully unlocking the potential of digital substations. One of the most promising advantages is the availability of digital data collected from substation equipment. By utilizing this data, overall power system operational efficiency can be enhanced, and equipment management can be optimized. Predictive maintenance can be implemented, enabling the early detection of potential equipment failures, minimizing unplanned outages, and reducing the need for emergency repairs, which contribute to unnecessary carbon emissions and equipment downtime. Ultimately, digital substations empower end-users to reduce greenhouse gas emissions, improve energy efficiency, and seamlessly integrate power systems, thereby supporting the carbon-neutral initiative and facilitating the transition towards a sustainable energy future. © 2023 IEEE.

One of the effective options to achieve higher power density and lower-weight electric motors for electric vehicle (EV) applications is to replace the conventional winding with a hairpin configuration. This novel concept has several advantages, but the biggest drawback is high AC loss. Therefore, as this type of winding utilizes in EV motors for high-speed application, the correct estimations of this loss are essential during the design procedure. This paper presents three primary approaches to model and calculate the AC loss of hairpin windings: analytical, hybrid model, and FEA methods. In addition, the FEA method is used to validate and evaluate the accuracy of two other methods. Accordingly, both analytical and hybrid model results agree with FEA results. However, the hybrid model has higher accuracy rather than the analytical method. © 2023 IEEE.

The increasing concern about climate change has been leading researches in many areas to investigate solutions for this issue. An emerging subject related to it is electric vehicles (EV). Although it is an important topic, there is still a lack of review papers about EVs modeling. In this context, this paper aims to bring a review about EV modeling to fulfill this gap. A wide bibliography review is made to cover different kinds of EVs modeling, in many aspects. As a conclusion, in some areas, authors do not diverge from each other, while in others may exist a large range of different ways to model the EVs. In this case, researchers should choose the modeling that fits the best for their research, which may vary in simplicity and computational effort. © 2023 IEEE.

Optical fiber displacement sensors (OFDS) offer several advantages over conventional sensors due to their compact size and immunity to electromagnetic interference. These are particularly useful for applications in confined spaces, including aeronautical turbines. The critical component of OFDS is the fiber bundle, whose response depends on the arrangement, radius, and number of fibers. We developed a straightforward yet effective method for designing OFDSs based on sensor specifications: working point, range, and sensitivity. This allows to determine the bundle geometry directly from the specified requirements. Among the explored designs, the tetrafurcated bundle stands out, composed by a transmitting fiber at the center, surrounded by three collections of receiving fibers. This paper demonstrates that tetrafurcated OFDS designs significantly enhance both the range and linearity. Additionally, they effectively reduce the dead zone of the sensors, enabling precise measurements even at very short distances. The design has been manufactured and experimentally validated. Simulation and measurements are in good agreement with an MSE of 0.26%. Our findings highlight the practicality and reliability of tetrafurcated OFDS designs, opening new possibilities for advanced displacement sensing applications. © 2024 SPIE.

This paper introduces the design of a Prescribed Performance Neural Network Model Predictive control (PPNNMPC) tailored for a 4 Degrees of Freedom (DoF) robot manipulator in trajectory tracking applications. The design of the proposed controller is formulated using Model Predictive control (MPC) methodology, which has the advantage of predicting the system's future behavior to achieve optimal robot control. Then, the prescribed performance function is incorporated into the control law by integrating the transformed error in the optimization process. The Prescribed Performance Function (PPF) maintains the tracking error within predefined limits, enhancing the system's transient response. Furthermore, integrating Neural Networks (NN) and prescribed performance functions into the control law design mitigates the common computational time drawback associated with MPC. Simulation results emphasize the superior efficiency of the suggested controller in contrast to the traditional model predictive control, demonstrating reduced overshoot, small settling time, improved computational efficiency, and accurate tracking of desired set-points. © 2024 IEEE.
