In this paper a new method of estimation of the induction motor electric parameters is presented and discussed. The proposed method uses the indirect approach that consists in estimating the continuous-time parameters by first fitting a discrete-time model to the data and then converting this model to a continuous-time version. The main contribution is that by using a polynomial pre-filter it is possible to compute the induction motor equivalent circuit parameters via an inverse transformation between the discrete-time and the continuous-time models. The procedure is potentially useful for the design of self-commissioning drives and may provide initial estimates to extended Kalman filtering type of procedures. The effectiveness of the proposed method is verified by simulated tests and results of the method are discussed.

A single-phase multilevel inverter with.-the function of power factor corrector and active power filter is proposed to reduce harmonic currents flowing into the power system and to draw a nearly sinusoidal line current with unity power factor. The circuit topology of the proposed inverter is based on a conventional full-bridge inverter with one AC power switch. The switching signals of the power switches are derived from the voltage balance compensator, current controller and detected operation region of mains voltage. A three-level PWM voltage pattern on the AC side of the inverter in each half cycle of mains frequency is performed. Simulation results are implemented to verify the validity and effectiveness of the proposed inverter with the function of power factor corrector and active power filter.

The paper presents an approach to sensorless speed control of a salient rotor permanent magnet synchronous motor, based on a high frequency signal injection scheme improved by the use of Kalman filtering. The rotor position estimation error signal is extracted from both the d- and q-axis components of the high frequency current in the estimated rotor position reference frame. Then it is processed by a Kalman filter which yields position and speed estimates, based on a parameter independent mechanical model. The problem of carrier recovery is addressed and a simple but effective solution is presented and analysed. Realistic simulations accounting for the inaccuracy of the digital implementation are presented and discussed.

Device descriptions are necessary for the integration of intelligent field devices in commissioning & maintenance tools, engineering systems or MES/ERP systems. Device descriptions comprise of device models and presentations based on the models (e.g. ASCII files). The XML concept may help to enlarge the application scope of device description because it is becoming one of the basic technologies of the fast growing internet and various e-engineering activities. Other realisations have to be based on the same device model (e.g. component interfaces). These issues are addressed from a modelling and implementation/realisation point of view.

The energy-storage of the static series compensator (SSC) dictates its capability to mitigate voltage dips. Capacitors are considered the most feasible energy storage for the SSC, particularly in high power applications. However, charging techniques of such energy-storage capacitors (ESC) have not been reported in literature. This paper proposes and describes the self-charging, technique that uses the voltage source converter of the SSC to charge its ESC. The active power, used in charging, is taken at the expense of the load active power. Thus two different cases are considered. One case considers that the phase angle of the load voltage is not allowed to jump during the charging process but the magnitude of the load voltage is reduced to 95-99% of its rated value. The other case assumes that the phase angle of the load voltage is allowed to jump. In this case, the VSC of the SSC extracts active power from the grid and injects reactive power into the grid. In both cases, a proper control algorithm is presented. PSCAD/EMTDC simulation verifies the validity of the proposed technique.

This paper describes the design of manufacturing objects done with the EXPRESS modeling language, and its implementation in a suite of Java classes. The Java suite constitutes an open manufacturing information system and a set of services, which are used to modify it. The rationale behind the objects model of the manufacturing information system is the fact that computer applications (CAD, CAM, CAPP or PAC) require static data from manufacturing objects like machine-tools, robots, ASRSs or AGVs but they use proprietary formats to store it. The proprietary formats lead to incompatibilities and interoperability problems among the applications. The proposed manufacturing objects and their implementation constitute a solution to facilitate data sharing and exchanging of flexible manufacturing resources.

This paper presents digital signal processor (DSP) based direct torque control scheme using space vector modulation (DTC-SVM) for permanent magnet synchronous motor (PMSM) drives. The analysis of PMSM shows that the increase of electromagnetic torque is proportional to the increase of the angle between the stator and rotor flux linkages and therefore fast torque response can be obtained by increasing the rotating speed of the stator flux linkage as fast as possible. The presented control strategy DTC-SVM is implemented in software of the DS1103 board. Simulations and experimental results well demonstrate the effectiveness of the proposed control scheme. Also comparison with conventional DTC scheme are given.

This paper proposes a soft-switching cell, based on the concept of input voltage cancellation or switching input supply, performed with a resonant commutated pole at the input of any bridge converter. The proposed auxiliary switching cell permits soft switching in all bridge topologies (half bridge, full bridge and 3-phase), in any load conditions, even with hi-directional input current. A simple control circuit, sampling the input current of the bridge converter, enables the adaptive operation of the soft switching cell, minimizing the circuit power losses.

This paper proposes a sensor-fusion technique where the data sets for the previous moments are properly transformed and fused into the current data sets to enable accurate measurement, such as, distance to an obstacle and location of the service robot itself. In the conventional fusion schemes, the measurement is dependent on the current data sets. As the results, more sensors are required to measure a certain physical parameter or to improve the accuracy of the measurement. However, in this approach, instead of adding more sensors to the system, the temporal sequence of the data sets are stored and utilized for the measurement improvement. The theoretical basis is illustrated by examples and the effectiveness is proved through the simulations. Finally, the new space and time sensor fusion (STSF) scheme is applied to the control of a mobile robot in an unstructured environment as well as a structured environment.

Input filters are usually adopted in electrical drives in order to improve the input current quality and to reduce the input voltage distortion. These filters; can determine instabilities, depending on the converter topology and drive control strategy. In this paper the stability of an electrical drive fed by a three-phase to three-phase matrix converter is analyzed considering two different input filter structures. A state average model of the whole system, assuming a constant power load, is proposed. The stability of the system is evaluated by analyzing the migration of eigenvalues of the system, which is linearized around the operating point. The analytical approach allows the determination of relationships showing the maximum output power of the matrix converter as function of the parameters of power supply and input filter. Theoretical considerations are supported by simulation results.
