The paper introduces the novel discrete feedback control called here impulse-based. It is believed that the proposed control scheme can be an adequate alternative to other existent robust control methods, like sliding-mode or bang-bang control, when solving the motion control problem with damping uncertainties. The impulse-based control paradigm is introduced while been close related to the well-known impulsive hybrid systems. The stable control convergence is shown for the bounded but unknown positive damping. Also the design of appropriate control parameters is provided in the closed analytic form. Numerical simulation example demonstrates the main control principles and helps to understand its advantages and drawbacks. An experimental case study of the motion control with nonlinear frictional uncertainties in vicinity to position settling discloses the practical relevance of the proposed method.

The dual-inverter fed Open-End Winding Induction Motor drive offers interesting possibilities for multilevel inversion. It needs two isolated power supplies to feed individual inverters to avoid the flow of zero-sequence current. Three Space Vector PWM schemes have been reported in the earlier literature, which facilitate the operation of the dual-inverter drive with a single power supply. This paper critically compares the performance of these three Space Vector PWM techniques for a dual-inverter fed Open-End Winding Induction Motor drive, which requires only one DC power supply. The criteria of comparison are: (i) the Total Harmonic Distortion (THD) in the voltage waveform (ii) the Total Harmonic Distortion (THD) in the phase current waveform (iii) RMS value of the stator flux ripple and (iv) switching and conduction losses of the switching devices. The relative merits and demerits of each SVPWM technique in these four aspects are presented. The performance of dual-inverter fed OEWIM drive with two isolated DC power supplies in these four aspects is used as a benchmark for comparison.

A hybrid electric vehicle (HEV) composed of an internal combustion engine (ICE) and a permanent magnet synchronous machine (PMSM) is considered in this paper. Batteries supply power to the PMSM. Referring to previous studies, other than delivering driving forces, PMSM can be exploited as an "active flywheel" and compensate the torque ripples generated by the ICE. These ripples are thus delivered to the DC bus, and result in an oscillating current in the battery, which will severely reduce the battery lifetime. Taking this into consideration, this paper aims to design an "active damping" so as to attenuate the oscillations in the DC bus voltage. This is achieved by connecting a supercapacitor in parallel with the battery, and constructing an effective controller. The influence of the current ripples is modeled as an external current perturbation. Moreover, transients and nonstationary fluctuations of the vehicles are considered as another perturbation. In order to realize perturbation rejection, a nonlinear control strategy with an inner fast loop and an outer slow loop is proposed. The controller is based on system passivity and energy distribution. The effectiveness of the control algorithm is verified through simulation.

Single-phase transformerless photovoltaic (PV) inverters have become more widespread in the solar energy market. This is due to the higher efficiencies they achieve together with the very low ground currents, which are their main advantages. In this paper a multilevel transformerless single-phase topology, based on the H-bridge with an active clamping, is proposed. Multilevel output voltage is achieved by using a split DC link and an active bidirectional switch to clamp the first leg in the H-bridge circuit. Therefore, a good behavior is achieved regarding total harmonic distortion (THD). A sinusoidal based pulse width modulation (PWM) strategy is also proposed to control the power converter. Numerical results show that the proposed PV inverter complies with the transformerless norms and regulations, operating with high efficiency, and being suitable for the transformerless PV inverters market.

In this paper, a general multirate approach is proposed for direct closed-loop identification of mechanical resonances above the Nyquist frequency without injecting any external persistently exciting (PE) signals. Based on the polynomial transformation technique, an extended least-squares (ELS) algorithm is designed to estimate parameters of the mixed-rate model, from which parameters of the fast-rate model is extracted. Convergence properties of the ELS algorithm are analyzed, and the parameter identifiability is ensured if the plant output sampling rate is non-integer multiples of the controller sampling rate. The performance of the proposed approach is evaluated by simulation results on the head-positioning servo control system of a hard disk drive (HDD) during track-following mode, where no external PE signal is added on.

Nowadays, the importance of real time condition monitoring and control for wind turbine (WT) is increasing because WTs are installed on remote site such as mountains and offshore. In this paper, we implement a monitoring and control system for a small-scale wind turbine. The monitoring and control system consists of data collection units, control unit and coordinator. The data collection units collect data from various sensors: temperature, humidity, atmospheric pressure, wind direction, wind speed and vibration. And the data collection units transmit sensing data to a coordinator. A ZigBee is used to communicate between a coordinator and data collection units. The coordinator is also communicate with PC and smart device through RS232 and Bluetooth, respectively. The GUI is implemented based on Android and LabVIEW to show the sensing data. The GUI based on LabVIEW can control the wind turbine direction using control unit.

The use of proportional resonant (PR) current controller in grid side wind power converters instead of the traditional proportional integral (PI) controller has gained a large popularity. Particularly its capability for compensating harmonics in the current waveforms is an essential feature. Due to the replacing of the generator side converter by a simple diode rectifier, harmonics with variable frequencies into dependence of the generator frequency appear in the current waveforms. To reach the IEEE standard for the total harmonic distortion (THD) a frequency adaptive PR-controller for compensating these harmonics is required.

Achieving high efficiency with improved power transfer range and misalignment tolerance is the major design challenge in realizing Wireless Power Transfer (WPT) systems for industrial applications. Resonant coils must be carefully designed to achieve highest possible system performance by fully utilizing the available space. High quality factor and enhanced electromagnetic coupling are key indices which determine the system performance. In this paper, design parameter extraction and quality factor optimization of multi layered helical coils are presented using finite element analysis (FEA) simulations. In addition, a novel Toroidal Shaped Spiral (TSS) coil is proposed to increase power transfer range and misalignment tolerance. The proposed shapes and recommendations can be used to design high efficiency WPT resonator in a limited space.

In this paper coupled inductor based high step up converter for dc micro grid is proposed. Switched capacitor based improved voltage extension cell is utilized to obtain high voltage gain. By using extended and improved voltage doubler cell, the voltage stress on the main switch and output diode are reduced. So active switches of low Rds(on) can be used and thus overall efficiency of the system is improved. Active clamp technique is incorporated to limit the voltage excursion on main switch and also to obtain zero voltage switching for both main and auxiliary switches which further improve the efficiency and power density. Design and analysis of the proposed converter is carried out and the result are verified by using PSIM Simulation package. Finally, a 500 W experimental prototype is build to verify the theoretical and simulation results.
