The basic structure of the rotating omega network do not contain mechanisms for ensuring sufficiently high quality of service for the selected group of messages. For this reason, an attempt has been made to develop a new transmission protocol utilizing the same transmission ring configuration and at the same time meeting the requirements of real-time applications. The article describes the new version of the transmission protocol, equipped with the CSMA mechanism. A essential feature of the proposed solution is to introduce different handled message classes, ensuring some of them priority in accessing the common base channel. The article also contains the most significant results of completed simulation tests, at the same time comparing them with the results obtained for earlier solutions

This article reports the main problem and the corresponding solution of the co-evaporation of Bi2Te3 and Sb 2Te3 films for the fabrication of Peltier elements. This main problem consists in the control of the deposition rates of the two elements: Bi or Sb and Te, which have very different vapor pressures. The control of the deposition ratio was achieved by means of a PID controller, which permitted the fabrication of thin-film Peltier elements that produce a temperature gradient in the order of 2degC between their hot and cold junctions, when measured at free air conditions

In advanced motor control systems, an accurate knowledge of motor parameters is essential in order to achieve good performances. Some of these parameters, such as stator resistances, are sometimes given by constructors, but they vary according to the operating conditions. This paper presents and compares two parameter identification methods of an actuator used in haptic interfaces which, in this case, is a permanent magnet synchronous machine (PMSM). Using these methods, the electrical parameters of the PMSM can be determined during different operating conditions. Physical parameters estimation of a dynamic 4-parameter model is performed on the one hand, using an output error identification method based on a non linear programming algorithm and on the other hand, using an identification method based on least-squares techniques and inverse models

Variation of switching frequency over the entire operating speed range of an induction motor (IM) drive is the major problem associated with conventional two-level three-phase hysteresis controller as well as the space phasor based PWM hysteresis controller. This paper describes a simple hysteresis current controller for controlling the switching frequency variation in the two-level PWM inverter fed IM drives for various operating speeds. A novel concept of continuously variable hysteresis boundary of current error space phasor with the varying speed of the IM drive is proposed in the present work. The variable parabolic boundary for the current error space phasor is suggested for the first time in this paper for getting the switching frequency pattern with the hysteresis controller, similar to that of the constant switching frequency voltage-controlled space vector PWM (VC-SVPWM) based inverter fed IM drive. A generalized algorithm is also developed to determine parabolic boundary for controlling the switching frequency variation, for any IM load. Only the adjacent inverter voltage vectors forming a triangular sector, in which tip of the machine voltage vector lies, are switched to keep current error space vector within the parabolic boundary. The controller uses a self-adaptive sector identification logic, which provides smooth transition between the sectors and is capable of taking the inverter up to six-step mode of operation, if demanded by drive system. The proposed scheme is simulated and experimentally verified on a 3.7 kW IM drive

Software component has been a main stream technology used to tackle issues such as software reuse, software quality and, software development complexity. In spite of the proliferation of component models (CORBA, .Net, JavaBeans), certain issues and limitations inherent to components are still not addressed adequately. For instance, composing software components especially those provided by different suppliers may result in faulty behavior. This behavior might be the result of incompatibilities between aging components and/or freshly released components and their respective interfaces. This paper, present an approach to tackle component interface incompatibilities via the use of a component and interface versioning scheme. This approach is designed as an extension to the compositional structured component model (CSCM), an ongoing research project. The implementation of this extension makes use of code annotations to provide interface versioning information useful in detecting interface incompatibilities

This paper presents a novel electromagnetic MEMS based micro-power generator with power density of 95 muW/cm3. The power density under careful design can be doubled to 190 muW/cm3. In addition, a complete design procedure for the micro-power generation system is presented. The procedure starts from the load power and voltage requirements and going backward in order to design the structure of the micro-power generator based on the available vibration input source (under known acceleration and fundamental resonant frequency). An example is assumed in order to demonstrate the design steps

The authors analyze high-frequency electromagnetic and acoustic scattering problems by the finite element coupled to Pade-type absorbing boundary conditions (ABCs). These new ABCs are local and can furthermore be applied on arbitrarily convex-shaped boundaries. The accuracy of the proposed method is investigated through different model problems. The obtained results show that relatively small computational domain can be considered in comparison with the classical second-order Bayliss- Gunzburger-Turkel ABCs while yielding accurate computations.

A new robust compliant motion control technique is presented for robot manipulator with certain hard nonlinearities. The control technique incorporates both time-delay estimation technique and ideal velocity feedback: the former is used to cancel out soft nonlinearities and uncertainties in dynamics model; the latter is used to mask hard nonlinearities. As a result, the proposed controller has simple structure and yet possesses robustness in the presence of certain hard nonlinearities. The same control structure can be used for both free space motion and constrained motion of robot manipulator. Through experiments on a 2-DOF SCARA type robot, the proposed controller has been compared favorably to other competent controllers, thereby confirming its effectiveness

The objective of this paper is to explore the time-optimal control problem arising in manufacturing applications involving point-to-point positioning. In such applications the motive forces are provided by electric motors, and the resulting current flow generates heat that leads to temperature rise. Manufacturing productivity is thus linked to a trade-off between the desire to reduce travel time and the need to avoid excessive temperature rise. This fundamental trade-off is explored for motion systems driven by two types of synchronous motors

Although piezoceramic actuators can generate extremely large forces, they normally exhibit small strokes in the range of tens of micrometers. A typical method to amplify these small strokes without sacrificing bandwidth has been to utilize a flexure-based leverage mechanism, where a piezo stack actuator deforms a specially cut metal block. In this paper, a new high-stroke piezoelectric actuator is presented, that employs a hydraulic amplification mechanism with a cylindrically shaped fluid chamber having a small opening at one side and a large opening at the other. When the piston in the larger opening is pushed by a piezo-stack actuator, the fluid is pressurized and pushes a shaft in the small opening through a longer distance. The stroke is determined by the area ratio of the two openings. Experiments showed that this new type of actuator could generate a longer stroke in the range of a few millimeters with a force of a few Newtons
