FPGA-based Model Predictive Control for High Frequency Variable Speed Generating Units 基于fpga的高频变速发电机组模型预测控制
V. Sabatini, L. Bigarelli, M. di Benedetto, A. Lidozzi, L. Solero, G. Brown
This paper deals with the design and implementation of high performance Model Predictive Control (MPC) strategy for stabilizing the output DC-link of an AC-DC converter in generating applications. The system is composed of a permanent magnets synchronous machine which is directly driven by a prime mover (i.e. internal combustion engine, gas turbine, etc..) and an AC-DC power converter. In such application, the control structure must be able to regulate the DC-link voltage as well as the dq-axes currents. Complete design of the Model Predictive Control strategy is described and tested, with reference to the internal reference generation and FPGA implementation. Being the system characterized by non-linear behaviors, the MPC approach is considered particularly suitable to overcome that issue.

D. Wilson, W. Weaver, G. Bacelli, R. Robinett
The purpose of this paper is to investigate Wave Energy Converter (WEC) technologies that are required to transform power from the waves to the electrical grid. WEC system components are reviewed that reveal the performance, stability, and efficiency. These WEC system individual components consists of; control methods, electro-mechanical drive-train, generator machines, power electronic converters, energy storage systems, and electrical grid integration. Initially, the transformation of energy from the wave to the electric grid is explored in detail for an individual WEC system. A control design methodology is then presented that addresses high penetration of Renewable Energy Sources (RES) and loads for networked AC/DC microgrid islanded subsystems. Both static and dynamic stability conditions are identified for the networked AC/DC microgrid system. Detailed numerical simulations were conducted for the electro-mechanical drivetrain system which includes; the dynamic responses, power generation for multiple wave conditions, and total efficiency of the energy/power conversion process. As a renewable energy scenario, the AC/DC microgrid islanded subsystem is employed to integrate an array of WECs. Preliminary Energy Storage System (ESS) power requirements are determined for the renewable energy scenario.

Micro Kinetic Energy Harvesting for Autonomous Wearable Devices 自主可穿戴设备的微动能收集
M. Magno, Dario Kneubuehler, Philipp Mayer, L. Benini
For wearable devices, the availability of energy is one of the main limiting factors of performance and lifetime. To overcome this issue, micro-energy harvesting circuits, which extract energy from the environment, are very promising. Among other environmental sources, kinetic energy could significantly improve the energy availability in wearable applications. However, the majority of kinetic energy harvesting circuits do not perform well with the low-frequency patterns found in human motion and are therefore not suited for wearable devices. This paper aims to overcome this limitation by developing a high-efficiency energy harvesting system, which is optimized for frequencies occurring in human motion. A Micro Generator System (MGS) 26.4, by Kinetron, has been exploited as a kinetic transducer to generate energy. The implemented kinetic harvesting system has been designed to maximize the energy conversion efficiency and supply and recharge wearable devices. The final design has been implemented and field-tested in different positions on the human body. Experimental measurements demonstrate the end-to-end efficiency of up to 84%, and an average power of up to $mathbf{624mu W}$, which is superior to the state-of-art for the type of MGS. Moreover, a preliminary evaluation of the correlation between acceleration and power harvested is presented. Using the values obtained from experimental data, we estimate that two hours of walking and 30 minutes of running per day can provide 1.4 joules of electrical energy.
对于可穿戴设备来说,能量的可用性是其性能和寿命的主要限制因素之一。为了克服这个问题,从环境中提取能量的微型能量收集电路是非常有前途的。在其他环境资源中,动能可以显著提高可穿戴应用的能源可用性。然而,大多数动能收集电路在人体运动中发现的低频模式下表现不佳,因此不适合可穿戴设备。本文旨在通过开发一种高效的能量收集系统来克服这一限制,该系统针对人体运动中出现的频率进行了优化。Kinetron公司开发的微型发电机系统(MGS) 26.4已被用作动能换能器来产生能量。所实施的动能收集系统被设计为最大限度地提高能量转换效率和可穿戴设备的供电和充电。最终的设计已经在人体的不同位置进行了实施和现场测试。实验测量表明,端到端效率高达84%,平均功率高达$mathbf{624mu W}$,优于目前最先进的MGS类型。此外,还对加速度与收获功率之间的关系进行了初步评价。利用实验数据得到的值,我们估计每天步行2小时和跑步30分钟可以提供1.4焦耳的电能。

Hydraulic PTO model emulator for WEC tank tests 用于WEC油箱试验的液压PTO模型模拟器
S. Giorgi, Costello Ronan, Bacelli Giorgio, Coe G. Rvan
In order to accelerate the overall power take off (PTO) design effort and to cheaply evaluate alternative designs, the construction of the real hydraulic PTO can be replaced with the design of a hydraulic PTO model emulator. This has the added advantage that it can be applied at model testing scales, where real hydraulic hardware would not give performance, representative of the full scale PTO (most likely, the scale PTO hardware and the full PTO hardware would be completely different but, even if similar, the operating points and performance would be very dissimilar). Finally, and most importantly for this work, the emulated PTO presents realistic interface to the controller while the emulated force signals are actuated by an electric motor. This paper reports the main results from a collaborative project between Wave Venture Ltd. and SANDIA National Laboratories, focused on the development of a hydraulic PTO model emulator, in order to carry out wave tank tests with the new SANDIA wave energy converter (WEC).
为了加快整体动力起飞(PTO)的设计速度和降低备选设计的成本,可以用液压动力起飞模型仿真器的设计来代替实际液压动力起飞(PTO)的构造。这还有一个额外的好处,即它可以应用于模型测试规模,真正的液压硬件不能提供性能,代表全尺寸PTO(最有可能的是,规模PTO硬件和完整PTO硬件将完全不同,但即使相似,操作点和性能也会非常不同)。最后,也是本工作最重要的一点是,仿真的PTO与控制器呈现真实的接口,而仿真的力信号由电动机驱动。本文报告了Wave Venture Ltd.和SANDIA国家实验室合作项目的主要成果,该项目重点是开发液压PTO模型仿真器,以便使用新的SANDIA波浪能转换器(WEC)进行波浪箱测试。

Improved Detection of Inter-turn Short Circuit Faults in PMSM Drives using Principal Component Analysis 基于主成分分析的永磁同步电机匝间短路故障改进检测方法
Frank Landry Tanenkeu Guefack, A. Kiselev, A. Kuznietsov
In this paper, a new online algorithm for detection and location of inter-turn short circuit fault in permanent magnet synchronous motor (PMSM) drives is presented. The developed algorithm is based on the well-know classical Park's Vector Approach (PVA), extended by the Principal Component Analysis (PCA) method. The PCA extension provides a significantly better robustness of the detecting performance against signal noise and allows to locate the fault phase. The detection, location of interturn short circuit fault as well as the noise tolerance is proven by simulation results under real-time conditions.

Configuration of Current and Speed Controllers for a Simplified Sensorless Vector Control System of IPMSM 简化IPMSM无传感器矢量控制系统的电流和速度控制器配置
M. Tsuji, S. Hamasaki, Kosuke Nakamura, A. Del Pizzo
Extended electro motive force (EMF) based sensorless vector control of IPMSM is one of the representative methods. We have proposed a simplified sensorless vector control system without using an observer on the basis of the extended EMF. In this paper, we have considered the transient characteristics for different combination of current and the speed controllers. A lineal model of proposed system is derived by considering those controllers and system stability is clarified by the root loci. Furthermore, simulation and experimental results are compared and discussed.

A Novel Control Scheme to Mitigate Unbalanced Magnetic Pull due to Eccentric Rotor in Three Phase Induction Motors 一种减轻三相异步电动机偏心转子不平衡磁拉力的控制方法
G. R. Bindu, Jasna Basheer
Rotating machines with low air gap are always prone to Unbalanced Magnetic Pull (UMP) due to eccentric rotors. As a consequence, rotor-stator rub contact occur leading to complete outage of the machine. This paper proposes a control scheme to reduce the effects of eccentricity in 3 phase induction motor by introducing Feedforward (FF) and Feedback (FB) control. Active Magnetic Bearings (AMB) are incorporated to implement this scheme. To analyse the UMP for statically eccentric rotor and also for conical rotor motion in a 3 phase induction motor, Finite Element (FE) method is utilised. These values are used to design the proposed controller.
