Pełny tekst źródłaSwitched Ethernet is an Ethernet LAN that uses switches to connect individual nodes.
This is popular because of its effective and convenient way of extending the bandwidth of
existing Ethernets. Switched Ethernet is being considered by the industry community because
of its open standardization, cost effectiveness, and the support for higher data rates up to
10Gbps. Even though many special-purposed solutions were proposed to support time
constrained communication over Switched Ethernet, still there were some doubts about the
real time handling capability of Switched Ethernet. To achieve reliable transmission
guarantees for real time traffic over Switched Ethernet, it is important to measure the
performance of Switched Ethernet networks for real time communication. In this thesis work
we have observed the average end-to-end packet delay for real time traffic over a Switched
Ethernet by simulation, which is very much essential for real time communication in
industrial applications, where the communication is time-deterministic. In our thesis we used
FCFS priority queuing in both the source nodes and switch. In this thesis we also discussed
about the feasibility analysis for fixed sized frames and some traffic handling methods. We
used 100mbp/s single full duplex Ethernet switch for our simulation. Finally simulation
analysis and simulation results are discussed. Our purpose of simulation of Switched Ethernet
networks is of good importance for the real time industrial applications.

Pełny tekst źródłaEthernet technology offers numerous benefits for networked Flight Test Instrumentation (FTI) systems such as increased data rates, flexibility, scalability and most importantly interoperability owing to the inherent interface, protocol and technological standardization. In a networked FTI system, the switch is a key component that allows data to be routed between Data Acquisition Units (DAU's), networked recorders, data processing and analysis stations. This paper provides an introduction to network switching concepts with a focus on its operation in a networked FTI system. The features of Commercial Off-The-Shelf (COTS) and FTI switches are compared demonstrating the benefits of FTI switches in terms of reliability, routing, throughput, latency, and start-up delays.

Pełny tekst źródłaThe success of the client/server paradigm for modern networked telemetry systems continues to stress the LAN that carries data generated from the acquisition front ends to the display workstations and the file servers on the LAN. As the number of LAN-attached devices such as Loral's System 500 Model 550 (Loral 550) telemetry front end, workstations, and file servers grows beyond two, the Ethernet LAN collision rates increase and the throughput slows down. At what point the network performance declines is a function of the specific application bandwidth demands required. This paper describes a new method for boosting LAN performance by providing Ethernet switching and protocol filtering. The performance of the LAN is critical to the performance of the complete telemetry enterprise architecture.

Pełny tekst źródłaENGLISH ABSTRACT: The Internet is evolving into a commercial platform requiring enhanced protocols and an expanded physical infrastructure allowing a better delivery from IP. Multi-protocol Label Switching (MPLS) is a technology enabling traffic engineering and virtual private network (VPN) provisioning. MPLS achieves traffic engineering by carrying the traffic over virtual connections called Label Switched Paths (LSPs) which are engineered based on QoS requirements such as delay, jitter and packet loss minimization or throughput maximization. This thesis proposes path finding and traffic distribution methods to be deployed in MPLS networks for traffic engineering LSPs. A flow optimization model based on a pre-planned routing approach separating path finding and traffic distribution is presented. This model is augmented by a threshold routing approach which routes the traffic based on thresholds expressing the maximum load level reached by network links. This routing approach moves the traffic away from thresholdmarked links to achieve low-utilized links/paths. The performance and routing capabilities of these methods are evaluated through designed software. A routing architecture implementing a two-layer signalling model for MPLS network is proposed and evaluated through simulation. v

Multiprotokol- etiketskakeling (MPLS), is 'n tegnologie vir die voorsiening van televerkeerbeheer en virtuele privaatnetwerke (VPN). MPLS verskaf televerkeerbeheer deur die verkeer te dra oar virtuele konneksies, wat bekend staan as etiketgeskakelde paaie, waarvan die ontwerp gebaseer is op vereistes vir diensgehalte soos vertraging, ritteling en die minimering van pakketverlies of maksimering van deurvoer. Hierdie tesis stel nuwe padvind- en verkeerdistribusiemetodes voor wat aangewend word in MPLSnetwerke om etiketgeskakelde paaie te beheer.

Hierdie model word uitgebrei deur 'n benadering van drempelroetering wat die verkeer roeteer en gebaseer is op drempels wat die maksimum ladingsvlak voorstel wat bereik kan word deur netwerkskakels. Hierdie roeteringsbenadering skuif die verkeer weg van drempelgemerkte skakels en bereik daardeur laaggebruikte skakelsjpaaie. Die prestasie en roeteringsvaardigheid van hierdie metodes word gevalueer deur selfontwikkelde programmatuur. 'n Argitektuur vir roetering wat 'n dubbellaagseinmodel implementeer vir 'n MPLS-netwerk, word aangebied en gevalueer met simulasie.

Following the recent trend, most internet services are moving towards cloud computing. Large data applications and growing popularity of cloud computing require hyperscale data centers and it will continue to grow rapidly in the next few years to keep up with the demand [4]. These cutting-edge data centers will require higher performance multi-core CPU and GPU installations which translates to higher power consumption. From 10MWatts of power, typical data centers deliver only half of this power to the computing load which includes processors, memory and drives. Unfortunately, the rest goes to losses in power conversion, distribution and cooling [5]. Industry members look into increasing backplane voltage from 12V to 48V in order to reduce distribution loss. This thesis proposes a novel Resonant Switched-Capacitor Converter using Multiple Resonant Frequencies to accommodate this increase of backplane voltage.

Abstract: This thesis is devoted to the study of the robust H∞ control problem of continuous-time switched linear systems subject to actuator saturation with polytopic uncertainties, considering an output-dependent switching law and a switched static output feedback controller. The proposed method offers new sufficient conditions based on linear matrix inequalities (LMIs) for designing the switched controllers using parameter-dependent Lyapunov functions. The method is based on a static output feedback H∞ control design recently presented in the literature that avoids linear matrices equalities (LMEs) and the need to impose any constraints on output system matrices, that is, the output matrices of the system are allowed to be of non-full row rank. In order to extend those results, the actuator saturation constraint is also studied. Theoretical analyses and simulation results show that these new procedures are less conservative than recent methods available in the literature. The conditions of the proposed methods are a particular class of Bilinear Matrix Inequalities (BMIs), which contain some bilinear terms as the product of a matrix and a scalar, related to a suitable convex combination and scalars parameters to provide extra free dimensions in the solution space. The hybrid algorithm Differential Evolution-Linear Matrix Inequality (DE-LMI), is proposed for obtaining feasible solutions of this particular NP-hard problem. Examples show that the proposed methodologies reduce the design ... (Complete abstract click electronic access below)

Many of the existing techniques for controlling switched systems either require the solution to a complex optimization problem or significant sacrifices to either stability or performance to offer practical controllers. In [13], it is shown that stabilizing, practical controllers with meaningful performance guarantees can be constructed for a specific class of hybrid systems by parameterizing the controller actions by a finite set. We extend this approach to the control of controllable switched systems by constraining the switching portion of the control input and fixing the feedback controller for each subsystem. We show that, under reasonable assumptions, the resulting system is guaranteed to converge to the target while providing meaningful performance. We apply our approach to the direct-injection stratified charge (DISC) engine and compare the results to that of a model predictive controller designed for the same application.

Electrolytic capacitors are often used for energy buffering applications, including buffering between single-phase ac and dc. While these capacitors have high energy density compared to film and ceramic capacitors, their life is limited and their reliability is a major concern. This thesis presents a series of stacked switched capacitor (SSC) energy buffer architectures which overcome this limitation while achieving comparable effective energy density without electrolytic capacitors. The architectural approach is introduced along with design and control techniques which enable this energy buffer to interface with other circuits. A prototype SSC energy buffer using film capacitors, designed for a 320 V dc bus and able to support a 135 W load has been built and tested with a power factor correction circuit. This thesis starts with a detailed comparative study of electrolytic, film, and ceramic capacitors, then introduces the principles of SSC energy buffer architectures, and finally designs and explains the design methodologies of a prototype circuit. The experimental results successfully demonstrate the effectiveness of the approach.

Pełny tekst źródłaConsidering that many processes and systems in real world applications can be modeled as switched systems, observers synthesis for this class of systems has received a growing interest in the last decades. This thesis intends to provide some contributions to the state-of-the-art in the field of robust state estimation for Switched Dynamical Systems subject to unknown parameters, external disturbances and/or measurement noise. One of the main feature of this dissertation regarding the available literature is that, no statistical evaluation of uncertainties is needed, only the knowledge of the interval boundaries to which these latter belong is required. The proposed methodologies are based on the so-called set-based approaches which provide an estimate of the set of admissible values of the state vector at each time-instant. The present thesis contributes and solves the problem of robust state bounding estimation using two paradigms which are: i) Interval Observer techniques based on cooperative system theory: where new interval observer structures are introduced and shown to have certain advantages over the classical interval observers when studying robustness and cooperativity issues. Sufficient conditions for proving the stability and cooperativity of the interval observer estimation error are provided in terms of Linear Matrix Inequalities (LMIs) constraints obtained using a combination of Lyapunov theory and Input-to-State Stability concept. In order to enhance the estimation accuracy and robustness, an explicit bound of the interval error is guaranteed and optimized for better estimation precision. ii) Set-membership observer techniques based on set theory: where switched observers based on interval characterization of the estimation error are proposed first. Next, new zonotopic state estimation approach based on minimizing the radius of the zonotope is developed. In this spirit, new method leading to the resolution of an optimization problem in the form of LMIs has been proposed. The above-mentioned contributions have been applied to state estimation and Fault Detection in Vehicle Lateral Dynamics. Application to real data recorded with a prototype equipped vehicle demonstrates the relevance and efficiency of the proposed approaches

Pełny tekst źródłaIn this thesis dissertation we present the design, stability analysis, numerical simulations and physical experiments of different controllers designed to drive the mechanical velocity of the switched reluctance motor (SRM). In the First and Second Chapters a brief description of the physics and construction of the SRM is presented, as well as the problem of control to be aboard, that is the velocity sensorless control of motors and the state of the art of this problem. The proposed solution is introduced and a summary of the published papers as well as the contribution are also presented.In the Chapter number three is presented the velocity sensorless and adaptive control of the SRM. It is assumed, in a first stage, that only mechanical velocity is unknown, uniform exponential stability of the errors is achieved in this scenario. In a second stage, conditions are stressed and in addition to the velocity, physical parameters are also assumed unknown, uniform asymptotical stability is achieved in this case and parameters estimation is guaranteed under a persistence of excitation condition. This controller consists of two loops, an internal loop based on a PI2D–type controller which is of particular interest given it is free-model; this loop drives the mechanical variables –that is position and velocity- towards a desired reference. An external control loop takes the electrical current towards a ‘’virtual” current reference which is generated based on a torque share approach. The controller is tested on numerical simulations, which are also presented.In the fourth chapter, a new approach on the modeling of the SRM is utilized to design the controller, in this scenario is assumed that the whole state and all the physical parameters are available, however this approach is thought to be suitable to observer based controller, whose ongoing research is being performed. The controller is composed by two loops, similarly to the one mentioned previously. This controller is selected because it is suitable for certainty equivalence control, that is, to substitute the “measurements” by the “observations” coming from a virtual sensor. Numerical implementation is performed on Simulink of Matlab.Finally, in the Chapter five, the experimental results carried out to evaluate the performance of the proposed controllers are presented, these are the PI2D and the adaptive PI2D controllers for the simplified model and the $PID$ controller for the novel modeling approach. In the first part, a brief description of the construction of the utilized bench is presented as well as the some technical characteristics. Three different velocity profiles were imposed to each of the overmentioned controllers –these are the so called smooth step, the saturated ramp and the sinusoidal reference- and good results, considering that the controlled variable is the velocity, were obtained. The last chapter corresponds to the conclusions of the performed research as well as to the future work

In this thesis, robust adaptive controllers are developed for classes of switched nonlinear systems. Switched systems are those governed by differential equations, which undergo vector field switching due to sudden changes in model characteristics. Such systems arise in many applications such as mechanical systems with contacts, electrical systems with switches, and thermal-fluidic systems with valves and phase changes. The presented controllers guarantee system stability, under typical adaptive control assumptions, for systems with piecewise differentiable bounded parameters and piecewise continuous disturbances without requiring a priori knowledge on such parameters or disturbances. The effect of plant variation and switching is reduced to piecewise continuous and impulsive inputs acting on a Bounded Input Bounded State (BIBS) stable closed loop system. This, in turn, provides a separation between the robust stability and robust performance control problems. The developed methodology provides clear guidelines for steady-state and transient performance optimization and allows for parameter scheduling and multiple model controller adjustment techniques to be utilized with no stability concerns. The results are illustrated for various systems including contact-based robotic manipulation and Atomic Force Microscope (AFM) based nano-manipulation.

System-on-chip (SoC) design provides integrated solutions to many applications such as computer systems, telecommunications, multimedia, consumer electronics, etc. One of the major challenges of designing a SoC chip is the communication architecture between heterogeneous components running different frequencies and possessing different characteristics. Most of the current communication architectures in SoC are based on dedicated wires and buses. As systems grow in complexity, the on-chip communication is expected to become critical for performance, power consumption, reliability, etc. However, the dedicated wiring and bus architectures have their limitation and do not meet these requirements. For next-generation SoC design, circuit-switched and packet-switched networks delivering messages between communicating components have been proposed. Such architecture is called network-on-chip (NoC) or micronetwork. In this thesis, we propose a scheduling scheme that efficiently schedules the connections in the switches in circuit-switched NoC architectures. The cost and latency of the switch in the circuit-switched network can be lowered down with our scheduler. Our algorithm uses three steps to solve these scheduling problems in circuit-switched networks. We translate the connection requirement table of a switch to the bandwidth requirement table with contention freedom in the first step. The second step is to assign the bandwidth requirement table with proper time slots and also calculate the waiting time in the output time slot table. And the last step is to optimize the output time slot table depend on the requirements to lower down the total waiting time in the NoC architecture. For having even more improvement in the future, we show the simulation results of the proposed algorithm to validate our ideas.
