The purpose of this research is to develop the electric assist wheelchair system for hemiplegic users. The proposed system is able to move in any direction by operating only one hand rim on one side. The hand rim can detect the user's operational intention by measuring contacting force and status of grasp and its style. The proposed system enables straight ahead, go back, gradual turn, pivot turn and stop based on the force being applied to the hand rim, whether the hand rim is grasped or not, and rotational speed of the hand rim. After the user operates the hand rim and releases it, the moving mode shifts to the deceleration mode. In the deceleration mode, the pseudo inertia deceleration is reproduced by motors. In this paper, we focus on the proposal of the system and the inertia deceleration by controlling motors, and verify how much it can reproduce in the outdoor environment.

At present, the researches on metal object detection (MOD) of magnetically coupled resonant wireless power transfer (MCR-WPT) system are mostly based on the alignment of the transmission coils and large size metal object, and MOD will fail when the transmission coils are misaligned or the metal object is small. In this paper, the fundamental and 7-th harmonic component of the square wave voltage source are used for energy transmission and MOD, respectively. A double resonance and a single resonance structure are adopted by the transmitting (Tx) end and the receiving (Rx) end respectively, and the fundamental and 7-th harmonic component of the Tx current are large, and the 7-th harmonic component of the Rx current is extremely small. The conversion circuit is used to filter out the fundamental component of the induced voltage of the detection coil group, so that the Rx current has little influence on the filtered detection voltage, and the MOD allows the transmission coils to be misaligned. The 7-th harmonic component of the Rx current is used to increase the detection sensitivity, and a double-layer balanced detection coil set is designed to further increase the detection sensitivity. Finally, the co-simulation of electromagnetic field and circuit by Maxwell and Simplorer software verifies that the metal object can be effectively detected regardless of whether the transmission coils are aligned.

Industry 4.0 follows the goal of promoting digitalization of manufacturing. Thereby converging information technologies and automation play a crucial role. These goals do not only require new softwares and information models but also require hardwares that offer more intelligence and bring more agility in production systems. The current developments in field of sensors introducing sensor 4.0 is an example of adapting the hardwares to industry 4.0 requirements. This is also necessary for other participating hardwares such as control devices. The control devices must be also designed to act more intelligent and provide interfaces to the other technologies like cloud computing and Cyber Physical Systems. In this paper, a new architecture for control devices will be introduced that operates as a bridge between industrial automation applications and IT technologies and provides a virtual platform for tests and simulations that run parallel to the control procedure. We refer to this architecture as “PLC 4.0”.

In this paper, a robustness evaluation of Unscented Kalman Filter (UKF) in comparison with the Extended Kalman Filter (EKF) for State of Charge (SOC) estimation of a lithium-ion battery based on capacity degradation model is investigated. To more comprehensively evaluate the performance of EKF and UKF, A first-order RC equivalent circuit model was used to characterize the dynamic behavior of a 30Ah lithium-ion battery. Based on the relationship between the Arrhenius formula, battery capacity, temperature and charge-discharge current accelerated stress, a fitting formula is obtained to predict the battery capacity degradation rate. The simulation results show that UKF outperforms EKF in terms of estimation accuracy and convergence rate against temperature effects, current and voltage noises.

In this paper a new rotor eccentricity fault detection method is proposed for the first time for brushless doubly-fed induction machines (BDFIMs). Due to the fact that BDFIMs are attractive alternatives to doubly-fed induction machines for wind power generation, paying attention to their fault detection is essential. Existing fault detection methods for conventional induction machines can not be directly applied to the BDFIM due to its special rotor structure and stator winding configurations as well as the complex magnetic fields. In this paper a new fault detection technique based on stator current harmonic analysis is proposed to detect rotor eccentricity faults in the BDFIM. The validity of the proposed fault detection method is verified by analytical winding function method and finite element analysis on a prototype D180 BDFIM.

Impedance-based stability analysis of voltage-source-converter-based high-voltage direct current (VSC-HVDC) systems evaluates interactions between power electronic converters and AC/DC systems by using their small-signal input admittances. Such an analysis requires an accurate calculation of the input admittance of the converter. This paper presents a method to approximate the input admittance of the modular multi-level converter (MMC) observed from its AC and DC terminals using a linearized dynamic phasor model. A nonlinear dynamic phasor model using variables in the stationary ABC frame is developed and linearized. The linearized dynamic phasor model is verified against a detailed nonlinear benchmark PSCAD model including submodule switching. Frequency scans are applied at corresponding inputs of the linear model to obtain small-signal transfer functions representing AC and DC input admittances of the converter. The resulting transfer functions are also verified against the PSCAD benchmark model.

In the last years, Renewable Energy Sources (RESs) have increasingly contributed to the power delivered by the grid. Despite the environmental benefits made by RESs, their unpredictable power production is responsible of variations in the voltage of the distribution lines that can be disruptive for the functioning of the supplied loads. Electric Spring (ES) is a device that faces such an issue by stabilizing the supply voltage of the critical load of a user in a simple but effective way. This paper is concerned with the stabilization characteristics of a user load supplied by a low-voltage distribution line and equipped with a reactive power-operated ES. After working out an ES model that facilitates the analysis of an ES-equipped user load, its stabilization characteristics are found for three types of line impedance, namely pure resistive, pure inductive and resistive-inductive. Comparison of the resultant characteristics shows the different performance of the ES-equipped user load under various types of line impedance.

Requirement engineering is a crucial part of the engineering process. The traditional methods of requirement engineering are time-consuming and human-centered. A well-established software requirement description model needs to ensure the accuracy and integrity of the transformation and is also hoped to be scalable, versatile, and efficient in transformation and transmission. This paper presents a method of requirement engineering, including constricted nature language requirement input pattern, and the formalized requirement description JSON model. This method provides convenience for requirement modification and validation that can satisfy the real-time constraints of industrial cyber-physical systems.

This paper proposes the auxiliary magnetic repeater-aided dual-output wireless charging with coupling analysis and power transfer capability considerations, in which the coupling resonance under different gap distances are concerned as well. This study analyzes the circuit architecture based on the simplification of equivalent models, by which parameters of resonant circuit are determined. Through the proposed design of a dual-output system, the balanced output power is seen to be achieved with higher flexibility. Experimental outcomes indicate that this proposed approach exhibits a satisfactory efficiency under various test scenarios. Test results concluded from comparisons between the proposed system and conventional system further supports the effectiveness of the auxiliary magnetic repeater for the increment of power transfer efficiency and system stability. The outcomes gained from practical tests are anticipated to serve as useful references for automated guided vehicles applications.
