This work deals with speed estimation in electric drives that include a Permanent Magnet Stepper Motor. On the one hand a nonlinear observer is designed, whereas on the other hand the rotor speed is estimated by using the dirty derivative from the measured position. By assuming model uncertainty and noisy measurements a comparison from the robustness point of view is presented. Advantages and disadvantages of both techniques are commented.

In the paper the radial and axial permanent magnet synchronous machines (RPMSM, APMSM) are classified in accordance with the types of design topologies and degree of active electromagnetic materials utilization. To realize an express comparison analysis of these machines the generalized geometric method is presented. Unlike the other methods this approach is distinguished by very small time for calculation of the ratio of radial and axial machines volumes as well as the similar ratio of mechatronic modules based on these machines. Derived a simple analytical expression enables to draw 3D plot of the volume ratio of compared machines at different number of poles and various geometrical sizes. The comparative study shows, that at the increased number of poles and at certain stator and rotor configuration the APMSM confidently exceed the RPMSM in term of torque/power density.

Fuel cell power conditioning systems consist of one or several voltage converters as well as energy storage devices. For generation of required voltages and controlled energy transfer appropriate converter topologies are necessary. Low-voltage power MOSFETs often can be used as switching devices for such converters. Possible ways of utilisation of low-voltage MOSFETs in different topologies and the resulting requirements are discussed.

The bus architecture consisting of bus converter and Point of Load (POL) is generally used as distributed power supply system for IT infrastructure equipments. The most important factor is the system stability in bus architecture design. The overlap between the output impedance of bus converter and input impedance of POL causes system instability, and it has been an actual problem. Increasing the bus capacitor, system stability can be reduced easily. However, due to the limited space on the system board, increasing of bus capacitors is impractical. The urgent solution of the issue is desired strongly. This paper presents the stability design for on-board distributed power system consisting of full-regulated bus converter and POLs. The output impedance of the bus converter and the input impedance of the POL are analyzed, and it is conformed by experimentally for stability criterion. As a result, the standard of the discrimination of stability on a frequency response of input and output impedance is clarified. Furthermore, the design process for system stability is proposed.

This paper proposes a new current regulator for IPMSM sensorless drives under high speed region. It has been pointed out that the conventional current control system for IPMSM becomes unstable under high speed region, which caused by position estimation error. First, this paper shows that this phenomenon is caused by position estimation error, and this instability is especially emphasized under high speed region. To overcome this instability, two degrees of freedom (2 DOF) controller is proposed in this paper. Stability using the proposed current regulator is then analyzed theoretically, and the proposed controller can enlarge stable region of position sensorless control for IPMSM drives, which can conclude that the proposed controller is superior to that using conventional one

Partnership for education will be one of the most important key points with respect to our information transfer for future students yet staying in high schools. Cooperation between universities of applied sciences and high schools gives the basis for transferring true messages about our study curriculum, best study behaviour and optimum profession chances to the kids. High school professors are the key personal partners for that information transmission and contact circle. Therefore, we give special trainings in engineering sciences to carefully selected teachers and assist them in technology, modern measurement systems, electronics, and robotics. This contribution describes some projects for training the teachers and assisting in education at high school level. The method to teach and help these partners is considered highly efficient in supporting the students to select the appropriate study in convergence to their abilities and interest.

In this work a fuzzy inference system is employed for the control of a PWM based direct torque control (DTC), driving an induction machine, to reduce ripple torque while limiting the current during start-up or when the stator flux magnitude changes. The proposed control scheme uses a fuzzy inference system to modulate the stator voltage vector applied to the induction motor, in magnitude and phase. This scheme allows for amplitude regulation according to the requirements of ripple reduction or stator current limitation. The proposed scheme performance was analyzed using simulation programs written in the C computer language and executed on a prototype system called PLATAFORMA III, developed by the SIEP Group at Universidad Simon Bolivar
