This paper studies the coupling between the specified load torque-speed characteristic, the motor size and weight and the inverter apparent power of a drive for a traction application. The main compromises between the sizes of the main components are analyzed in the case of a surface mount PM permanent-magnet motor drive. An efficient p.u. approach is proposed and validated by a comparative analysis with the design results of a CAD environment with global optimization

In this paper, a novel high performances modulation unit for high power multi drive application is presented. It is mainly based on a intelligent PLD (programmable logic device) based modulator connected via filed bus to several slave power units. The PLD master unit is characterized by a multimodulation strategy which implements a double strategy: a variable frequency technique, whose target is to change the switching frequency on the base of the power modules dead time and a "single switch commutation technique", which allows to almost completely eliminate the blank time imposition during the switching operation. The proposed technique has been tested in a high performances parallel connection of VSI (voltage source inverter)

Reactive power compensation in a power distribution network plays a vital role in improving power quality, correcting power factor and maintaining constant distribution voltage. Among the various compensation devices available voltage source converter (VSC) based controllers offer very fast response to reactive power demand and thus can be effectively used for power factor correction and voltage regulation. One such VSC based controller called the distribution static compensator (DSTATCOM) proves to be a viable alternative to the conventional static var compensators (SVC). Further, the control algorithms applied to the DSTATCOM play a vital role in its performance. In this paper, the control algorithms applied to a DSTATCOM for reactive power compensation and power factor correction are reviewed and analyzed through digital simulations

Permanent-magnet AC (PMAC) servomotor is finding expanded use in high-performance applications. Because servomotor is always required to instantaneously provide 3 times rated torque, how to protect it from overheating is a very important issue. In this paper, a simplified thermal model is presented and its implementation is described. The application on a 400 W servomotor shows a good agreement between test and estimation

Parallel robots are increasingly being used in industry for positioning and alignment. They have the advantage of being rigid, quick, and accurate. However, most parallel robots have very limited rotational capabilities and in cases where unlimited rotation is necessary, the only option used to be adding a rotary table. There however exists one overlooked XY-theta parallel robot design that can reach any point within a circular workspace at any orientation. This unique design consists of three pivots moving independently along a common circular path. These pivots are connected individually to three linear guides attached to a mobile platform in a symmetric "Y" shape. By studying the kinematics of this parallel robot, this paper shows that not only is the dextrous workspace large but the kinematic accuracy is high and uniform

This paper presents a basic structure for an international standardization of an autonomous free-flying space robotics servicing mission. Servicing and rescuing failed satellites/spacecrafts can make a benefit of such a standard. In orbit-servicing measures and definitions have been introduced which include: mission statement, objectives, stages, tasks and operations, modules, modularity, accessibility, reliability, monitoring, berthing, communication, programming. This structure may serve as a first step towards unifying servicing standards and building an international in-orbit satellite servicing station. Finally, using a control-oriented modeling approach is proposed which is suitable for a free-flying space robot with/without interaction with a target satellite, then simulation results are presented to demonstrate the proposed in-orbit servicing mission for the Hubble space telescope

This paper presents an original direct torque fuzzy control (DTFC) of a voltage source PWM inverter fed induction motor drive. First a direct torque fuzzy control (DNFC) of a voltage source PWM inverter fed induction motor drive is presented and its performances are compared to those of a classical DTC control. Then a variable gain PI speed controller is introduced to improve these performances. The DTFC control scheme uses the stator flux amplitude and the electromagnetic torque errors through two fuzzy controllers to generate the amplitude and the angle of the reference voltage which is used by a space vector modulator to generate the inverter switching states. Simulation of the DTFC induction motor drive using VGPl for speed control shows promising results. The motor reaches the reference speed rapidly and without overshoot, load disturbances are rapidly rejected, torque and current ripples are greatly attenuated and variation of the stator resistance is fairly well dealt with

The performability of disk arrays systems has been studied before. However, in the case of imprecise data, a fuzzy model can be the base for the performability analysis. In this paper a performability analysis of a disk array using a Markov reward model (MRM) is presented. The model considers the repair as the reconstruction (rebuild) of the redundancy, not as a hard drive replacement. With traditional, crisp arithmetic, for each change in a single model parameter the model would need to be run again, resulting in a family of curves difficult to interpret. In the approach presented in this paper, the rewards for each of the states of the MRM, as well as other disk array parameters are expressed through fuzzy numbers. The use of fuzzy arithmetic for the performability estimation of a disk array proved significant advantages. First, the model was able to capture the uncertainty variance of each of the model parameters. Secondly, as opposed to traditional, crisp arithmetic approach, the presented model provides the estimation of the lower and upper boundary of the system performability with a single run of the model

The present paper is devoted to the development of a mobile robot, which is capable of following a pre-defined track and avoid collision with obstacles ahead of it. The avoidance of collision is implemented using a series of calculations and intelligent decision making support. The decisions are made according to the feedback given by the different sensors on the mobile robot, and a multilevel knowledge base programmed in the robot's controller. The robot accommodates first order logic and meta-production rules for as knowledge representation models to describe the robot's knowledge base, which defines the robot's behavior. The use of meta-production rules allows the robot's knowledge base to be fairly simple, but also flexible and extensible. Although the current intelligent capabilities of the robot are limited by avoidance of a single obstacle, the robot's knowledge base can be extended by adding new semantic and meta-production rules, that would result extensions of the robot's intelligence by new capabilities to avoid more complicated and especially multiple obstacles
