Almost all people who get laryngeal cancer are treated by laryngectomy. However, this treatment affects their voice since the larynx will be removed. This research presents a technique which can recover their voice to communicate with others again. The technique is esophageal speech;this technique does not require any additional device but it needs only a continuously training from speech therapist. In additional, the training software for esophageal speech is designed and developed based on three speech characteristics which are tempo, loudness and duration of speech. For more attractive, we developed into computer game-based. The experiment is divided by two groups of users;normal speakers and esophageal speakers. The results of experiments are evaluated by using Mean Opinion Score, and the score are 4 from esophageal speakers and 3.7 from normal speakers.

A Droop controller is intrinsically a Phase-Locked Loop

Annual Conference of the IEEE Industrial Electronics Society

作者： Qing-Chang Zhong Dushan Boroyevich Dept. of Automatic Control and Systems Engineering The University of Sheffield Center for Power Electronics Systems Virginia Polytechnic Institute and State University

ISBN: (纸本)9781479902255

This paper demonstrates that a droop controller, which is fundamental to the operation of power systems and now the parallel operation of inverters, is intrinsically the same as a phase-locked loop (PLL), which is widely adopted in modern electrical engineering. This bridges the gap between the two communities working on droop control and PLLs. As a result, droop controllers and PLLs can be improved and further developed via adopting the advancements in the other community. This also offers insightful understanding to power systems that have inverters and generators mixed together and leads to significant technological breakthrough for the grid connection of renewable energy. For example, there is no longer a need for grid-connected inverters to have a phase-locked loop and a droop controller at the same time.

International Symposium on Advanced Topics in Electrical engineering

This paper presents a comprehensive study on the wind power impact with increasing penetration on frequency stabilization in restructured power system scenario. The focus of the study is on faster and smoother settlement of frequency and tie-line power. A large penetration of wind power generation causes imbalance in power system because of its intermittent output. The wind power generation system does not provide inertia and isolates from the grid during disturbances but this possibility becomes milder if wind power generators also contribute to system inertia. The proposed control scheme with fuzzy logic uses frequency deviations to provide fast active power support, which blocks the fall in frequency and tie-line power during transient conditions. The simulation studies have been conducted in a two-area interconnected power system in restructured environment.

Differential power processing (DPP) isolated-port architecture with submodule integrated converters (subMICs) enables improved energy capture in photovoltaic (PV) power systems. This paper describes a control scheme for flyback subMICs operating in discontinuous conduction mode (DCM). The duty-cycle is driven in proportion to a voltage error, with no further processing, thus eliminating the need to measure or to control the current explicitly. The approach is well suited for very simple, analog PWM controller implementation, but the resulting control loops become nonlinear. The system stability is demonstrated using the Lyapunov stability theorem. Experimentally measured module-level efficiency is greater than 95% for a 72-cell PV module having 3 substrings with solar irradiation of 80%, 60% and 40%, respectively.

ISBN: (纸本)9781479902255

This article aims to present the design of a 4.5-V, 450-mA low drop-out (LDO) voltage linear regulator based on a two-stage cascoded operational transconductance amplifier (OTA) as error amplifier. The aforementioned two-stage OTA is designed with cascoded current mirroring technique to boost up the output impedance. The proposed OTA has a DC gain of 101 dB under no load condition. The designed reference voltage included in the LDO regulator is provided by a band gap reference with the temperature coefficient (T_γ) of 0.025 mV/℃. The proposed LDO regulator has a maximum drop-out voltage of 0.5 V @ 450 mA of load current, and has the worst case power supply rejection ratio (PSRR) of [54.5 dB, 34.3 dB] @ [100 Hz, 10 kHz] in full load condition. All the proposed circuits are designed using a 0.35 μm CMOS technology. The design is checked in order to corroborate its performance for wide range of input voltage, founding that the circuit design works fine meeting all the initial specification requirements.

A study on filtering aspects of airborne wind energy generators is presented. This class of renewable energy systems aims to convert the aerodynamic forces generated by tethered wings into electricity. The reconstruction of the wing's position and velocity is investigated here. Different sensor setups are considered, and the related sensor fusion algorithms are presented. The different approaches are compared through experiments on a small-scale prototype. The designed filtering algorithms rely purely on kinematic laws, hence the results obtained are representative also of systems with larger size and different wing designs.

The rise of global competition and the demands for mass customization observed in recent years are the main shaping forces of the manufacturing domain. Current approaches to industrial production automation are not suitable to cope with the resulting increasing requirement in term of system agility and sustainability. While a quite large amount of innovative and sound technical solutions for automation address such an issue, it is not clear how the new generation of automatic production system will be economically connoted. This work proposes a first step towards an economical characterization of the Evolvable Paradigm: one among the most promising aforementioned innovative industrial automation technologies. A basic description of the state-of-the-art of the related Evolvable Assembly/Production system allows inferring a cost model able to account for such an installation. This, in turn, enable a quantitative description of how the focal innovative approach enables a more effective and rational use of industrial automation.

This paper presents two modern modulation techniques applied to three phase inverters from a hardware implementation point of view. The considered techniques are the sinusoidal pulse width modulation with zero sequence injection and the space vector modulation. Both these techniques conduct to the same result regarding supply voltage usage efficiency and harmonic content of the resulted signals. The implementation was developed in Matlab-Simulink, using the system Generator software, and validated through simulation. Both the modulation algorithms were implemented in hardware on a low cost FPGA, and the resulted designs are compared for resource usage efficiency, obtained speed and easiness of integration within a complex AC drive control system.

In this paper has been designed an optimal permanent magnet synchronous motor (PMSM) by using a coupled procedure composed by electric circuit equivalent scheme and finite elements method (FEM). The optimal solution is based on a minimization of specific cost of active materials by genetic algorithms. For this approach was taken into consideration different restrictions according to electromagnetic stress limits. The final solution is checked by running the operation characteristics.
