Nowadays, the research of the battery with higher energy density is increasing. Due to the higher energy density of battery, more and more machines are powered by batteries, such as electric vehicle, electric stacker trucks, and electric boat. These battery applications must to control and manage the batteries by Battery Management System (BMS). The state of charge (SOC) of battery and the battery balancing are two very important topics of battery management system. This paper proposed an improved coulomb counting method with equivalent circuit model, by using equivalent circuit model to provide the initial SOC, and then coulomb counting method to estimate capacity. Balanced single battery capacity was made by the bi-directional DC-to-DC buck-boost converter. The battery module can have accurate estimate SOC estimation and balance ability.

Recently, face the high replacement of products and the pressure of taking new products into market in time, the designers need to shorten the used time. The engineer need to design high performance electronic products within limited time. We need to accomplish many circuit interconnects in a small Printed Circuit Board. This reason make much more complicated and difficult situations. The designers not only consider circuit interconnect but also consider circuit performance. In this thesis, the first part is three dimensions interconnect investigation of system in package. We analyse the discontinue effect of transfer layer and compare traditional via model with via model established in this thesis. We also study via structure to improve SSN.The second part is the equivalent long transmission line by Modify-T Model. The chip of Modify-T Model equivalent long microstrip line are 3cm,3cm+3cm,and 6cm.We compare the area and the difference of the performance.

Texto completoFlexibility effects on robot manipulator design and control are typically ignored which is justified when large, bulky robotic mechanisms are moved at slow speeds However, when increased speed and improved accuracy is desired in robot system performance it is necessary to consider flexible manipulators. This project simulates the motion of a single-link, flexible manipulator using the Equivalent Rigid Link System dynamic model and experimentally validates the computer simulation results Validation of the flexible manipulator dynamic model is necessary to ensure confidence of the model for use in future design and control applications of flexible manipulators.

The research objectives of this dissertation are stated as follows. First, via some existing techniques, the linear singular system can be decomposed into an equivalent regular system with a feedthrough term, from input to output. Second, the high-gain optimal linear quadratic analog tracker and observer for this equivalent model are developed. Third, based on this linear quadratic analog tracker (LQAT) and observer, the prediction-based digital redesign and alternative digital redesign methodologies are carried out, respectively, to derive the digital tracker for the state of the digitally controlled model closely matches the state of theoretically well-design continuous-time model with the same input and initial condition; and the digital observer while, as the states of both digitally controlled model and continuous-time model are unmeasured in turn. Finally, an iterative learning control (ILC) strategy, by combined with the LQAT, for the continuous-time linear time-variant (LTI) regular model with a singular feedthrough term is presented. The tracking performance improvement is achieved through the initial control input obtained by the LQAT, and the initial condition constraint, in typical ILC design, is removed by together with initial state learning law. Some illustrative examples are given to demonstrate the effectiveness of the proposed methodologies.

Buscar texto completoDue to increasing regulation on emissions and shifting consumer preferences, the wide adoption of battery electric vehicles (BEV) hinges on research and development of technologies that can extend system range. This can be accomplished either by increasing the battery size or via more efficient operation of the electrical and thermal systems. This thesis endeavours to accomplish the latter through comparative investigation of BEV integrated thermal management system (ITMS) performance across a range of ambient conditions (-20 °C to 40 °C), cabin setpoints (18 °C to 24 °C), and six different ITMS architectures. A dynamic ITMS modelling framework for a long-range electric vehicle is established with comprehensive sub models for the operation of the drive train, power electronics, battery, vapor compression cycle components, and cabin conditioning. This modelling framework is used to construct a baseline thermal management system, as well as for adaptation to four common systems. Additionally, a novel low-temperature waste heat recovery (LT WHR) system is proposed and shown to have potential benefits at low ambient temperatures through the reduction of the necessary cabin ventilation loading. While this system shows performance improvements, the regular WHR system offers the greatest benefit for long-range BEV drive cycles in terms of system range and transient response. With an optimal thermal management system found for long range BEV’s this system is then used as a boundary condition for a study on cooling of the battery. Battery conditioning, health, and as a result their along cell and system lifetime remains an additional concern of consumers as well as thermal systems engineers seeking to ensure safety and ensure longevity of EV battery cells. Three typical coolant flow orientations are studied to compare them under different flow conditions and thermal interface material performance. The battery cooling model is then coupled to the previously established dynamic modelling environment to demonstrate the added modelling capability (and necessity) for incorporating module-level cooling performance in both battery cooling studies and transient ITMS environments.

Texto completoThe doctoral dissertation concerns about architectural heritage represented by the so-called “Baraccato” houses. The most ancient Baraccato structural system was defined by the Bourbon Government in the late 18th century and it represented the anti-seismic model for the reconstruction of several italian cities between 1783 and 1908. In such constructions the load-bearing system, composed by a timber-framed masonry infill, is the result of a "seismic memory" based on a experience and pratical knowledge whose scientific validity has been mostly verified only from an empirical point of view. For this reason, the main scope of the thesis was to assess the seismic efficiency of the constructive system by defining a specific mechanical model. In addition, the research deals with the analysis and description of the typological and morphological aspects that characterize the Baraccato houses found in some examples still existing in Calabria, a region in the South of Italy. One of the most emblematic buildings of this construction technique, the Episcopal Palace of Mileto, was analyzed in detail and has been the object of analysis of the mechanical model proposed. With reference to the research areas of interest described above, the thesis consists of three main parts: Historical and constructive analysis The first part explores the genesis and spread of the Baraccato technique with regard to similar examples, widespread in the territories of high seismic risk of Italy and more generally in the world. The research shows the constructive characteristic of the Baraccato building, identifying the anti-seismic quality. In addition to the "historical reconstruction" of the Baraccato technique, the first part of the thesis contains the results of a survey on existing heritage aimed at evaluating the extent of Baraccato heritage in different centres of Calabria and its conservation status. Mechanical analysis In the central part of the thesis, the mechanical model proposed for the analysis of the most ancient Baraccato system is shown. The aim was to translate the empirical intuitions that characterize the structural configuration of the Baraccato buildings with a modern scientific language. Through a multiscale mechanical analysis, a simplified modeling methodology has been defined to describe the complex mechanical phenomena that characterize the seismic behaviour of mixed wood and masonry structures. As a matter of fact, in a first phase a micro-mechanical analysis was carried out on a single Baraccato wall, already undergoing experimental tests at the CNR-Ivalsa Laboratory of Trento in 2013, which allowed the calibration of the mechanical parameters that characterize the wall elements, like wooden frame, connections and masonry. Subsequently, the simplified analysis approach, called EFM (Equivalent Frame Method), widely used in the literature for the study of masonry structures, has been implemented for the seismic analysis of an entire Baraccato building. Case study The last part of the thesis concerns about the study of an emblematic case of eighteenth-century Baraccato house. In particular, the Bishop palace of Mileto (South Italy), because of its enormous historical, cultural and constructive value, was chosen as the subject of a specific study, aimed at application and validation of mechanical model defined. In addition, the poor state of conservation of the building has allowed to detect the original construction solutions, providing a rare testimony of the original Baraccato technique. As a matter of fact, in order to avoid the complete loss of the Bishop's Palace, affected by several collapses and acts of vandalism in the last few years, the thesis contains the results of a recovery activity, material and cultural life, promoted by the Architecture Department of Rome Tre University, which has recently led to the beginning of a procedure for affixing the architectural constraint on the Palace, which should guarantee its definitive preservation and enhancement.
