This paper presents the design of a 36kW V-type rib-less Interior Permanent Magnet Synchronous Machine (IPMSM) for EV propulsion, with a focus on optimizing motor efficiency through a PWM harmonic-based approach. The core of this design is an innovative analytical current harmonic model (ACHM) that specifically addresses iron losses in 3-phase 2-level voltage-source inverters. This model effectively captures the effects of PWM harmonics, significantly enhancing motor efficiency across various operating points. The efficiency improvements are vividly demonstrated in maps that highlight the impact of PWM harmonics on motor performance. The practical application of this PWM harmonic-focused design is validated through rigorous electromagnetic FEA and prototype testing, confirming its suitability for high-performance EV propulsion systems.

The paper solves the problem of building a control system for steam pressure at a Combined Heat and Power Plant (CHP). Functioning of the regulator in terms of practical implementation is analyzed. The main features of the technological process which affect the effective management of the automation object are identified. It is considered complex coal-fired CHP plants with common steam line and drum boiler in a combined cycle of generating electricity and heat which provides a common primary frequency control in the power system. Authors was obtained the mathematical model of the plant for one of the boiler units of the Blagoveshchensk CHP. Data processing was carried out by authors with the help of the method of passive experiment. Analysis of the system operation was shown that the control plant can be described with a sufficient degree of accuracy by a parametrically undefined model with changing structure and delay. Various Matlab simulation sessions demonstrate the good quality of the proposed solutions when changing both the parameters and structure of the system. © 2022 IEEE.

The application of unmanned vehicles in industrial cargo transportation is becoming increasingly widespread, particularly playing a significant role in transporting heavy-duty goods. However, when performing such tasks, whether in single-vehicle transportation or multi-vehicle collaborative transportation, the occurrence of wheel failures can potentially lead to serious safety accidents. Therefore, this paper proposes a fault-tolerant control scheme, establishing a kinematic model considering disturbances and failures, and adopts model predictive control for trajectory tracking. Additionally, an extended state observer is introduced to observe system states and counteract disturbances. To address potential failure issues, a controller reconstruction strategy is proposed. Finally, the effectiveness and superiority of the controller is validated through numerical simulation and comparative experiment. © 2024 IEEE.

In this paper, we investigate the trajectory tracking control problem for autonomous underwater vehicles (AUVs) with time-varying external disturbances of currents and waves in the sea. To solve the problem, a fixed-time extended state observer (FTESO)-based tracking controller is proposed. Firstly, by using the extended state observer, the FTESO is proposed for estimating the external disturbances and the velocities of the AUV within the fixed convergence time. Based on the FTESO, the fixed-time controller is proposed for reducing the tracking errors and improving robustness performance. Theoretical analysis is given, which shows that the unknown external disturbances can be compensated and tracking error can converge to zero within the fixed time. Simulation results show that the proposed FTESO controller not only guarantees the fixed-time convergence but also reduces the trajectory tracking errors of the AUV. © 2021 Chinese Automatic control Society and John Wiley & Sons Australia, Ltd.

In variational quantum algorithms (VQAs), the most common objective is to find the minimum energy eigenstate of a given energy Hamiltonian. In this paper, we consider the general problem of finding a sufficient control Hamiltonian structure that, under a given feedback control law, ensures convergence to the minimum energy eigenstate of a given energy function. By including quantum non-demolition (QND) measurements in the loop, convergence to a pure state can be ensured from an arbitrary mixed initial state. Based on existing results on strict control Lyapunov functions, we formulate a semidefinite optimization problem, whose solution defines a non-unique control Hamiltonian, which is sufficient to ensure almost sure convergence to the minimum energy eigenstate under the given feedback law and the action of QND measurements. A numerical example is provided to showcase the proposed methodology. © 2023, CC BY-NC-ND.

Electric vehicles (EVs) have experienced an unprecedented increase in their penetration; in well developed countries; due to the advancement of battery technology and the need to make transportation more environmentally friendly. As a result of this trend, EVs have become an integral part of those countries power grid ecosystem, where they may be used as both a source, and a consumer of energy. However, cybersecurity risks associated with large fleets of EVs within the power grids can significantly impact the normal operation of distribution systems. This paper considers the cyber-attack consequences, from attackers’ perspective. The cyber attackers under study target the charging price (CP) by increasing the CP in off-peak hours and accordingly subsiding it in on-peak hours. A two-stage optimization framework is proposed to identify the most important ultra-fast charging stations (XFCs) under the cyber-attack, meanwhile, the EV users’ response to the compromised CP is considered. Then, the proposed model is implemented on a modified IEEE 123-bus distribution test system, and the effectiveness of the model is proved through some case studies. In particular, they demonstrated that the amount of load shedding is increased by 8.198 MW when the EV user response is taken into account.

On the Equilibrium of a Class of Leader-Follower Games with Decision-Dependent Chance Constraints

arXiv 2024年

作者： Wang, Jingxiang Wang, Zhaojian Yang, Bo Liu, Feng Guan, Xinping The Key Laboratory of System Control and Information Processing Ministry of Education of China The Department of Automation Shanghai Jiao Tong University Shanghai China The State Key Laboratory of Power System The Department of Electrical Engineering Tsinghua University Beijing100084 China

In this paper, we study the existence of equilibrium in a single-leader-multiple-follower game with decision-dependent chance constraints (DDCCs), where decision-dependent uncertainties (DDUs) exist in the constraints of followers. DDUs refer to the uncertainties impacted by the leader’s strategy, while the leader cannot capture their exact probability distributions. To address such problems, we first use decision-dependent ambiguity sets under moment information and Cantelli’s inequality to transform DDCCs into second-order cone constraints. This simplifies the game model by eliminating the probability distributions. We further prove that there exists at least one equilibrium point for this game by applying Kakutani’s fixed-point theorem. Finally, a numerical example is provided to show the impact of DDUs on the equilibrium of such game models. Copyright © 2024, The Authors. All rights reserved.

The article studies algorithms synthesis of a multiply connected system for controlling non-affine plants, the state variables of which are not available for direct measurement. It is shown that the decentralized control law constructed on the basis of the hyperstability criterion eliminates the influence of non-linearities and compensates external and parametric perturbations in the tracking multiply connected system with the required accuracy. © Published under licence by IOP Publishing Ltd.

Euler-Lagrange (EL) systems represent a crucial and large class of dynamical systems, and a precise model of the true system would be beneficial in planning and tracking problems. This work aims to learn an unknown EL system using noisy measurement data to achieve improved data utilization efficiency. Specifically, for the considered EL system, a linear representation of the system is constructed using the Koopman operator, which is further characterized by sample data using Willems’ fundamental lemma. Moreover, an event-triggered learning mechanism is proposed to improve data utilization efficiency, and it is designed based on the analysis of the learning error bounds. The effectiveness of the proposed event-triggered learning approach is validated through a manipulator example.
