Abstract:
This paper presents the development of a contactless sensing system and the dynamic evaluation of an air-bearing-based precision wafer positioning system. The contactless positioning stage is a response to the trend seen in the high-tech industry, where the substrates are becoming thinner and larger to reduce the cost and increase the yield. Using contactless handling it is possible to avoid damage and contamination. The system works by floating the substrate on a thin film of air. A viscous traction force is created on the substrate by steering the airflow. A cascaded control design structure has been implemented on the contactless positioning system, where the inner loop controller (ILC) controls the actuator which steers the airflow and the outer loop controller (OLC) controls the position of the substrate by controlling the reference of the ILC. The dynamics of the ILC are evaluated and optimized for the performance of the positioning of the substrate. The vibration disturbances are also handled by the ILC. The bandwidth of the system has been improved to 300 Hz. For the OLC, a linear charge-coupled device has been implemented as a contactless sensor. The performance of the sensing system has been analysed. During control in steady-state, this resulted in a position error of the substrate of 12.9 μm RMS, which is a little more than two times the resolution. The bandwidth of the OLC is approaching 10 Hz.

Abstract:
Micro-Electro-Mechanical Systems, or MEMS, has been a continuously growing technology during the last decades. Since 1959, when the theoretical physicist Richard Feynman introduced the concept of nanotechnology in his famous talk "There is plenty of room at the bottom", several companies and researchers have been involved in the permanent improving of these devices. MEMS is the technology of microscopic devices, particularly those with moving parts and it is widely used in both sensing and actuating applications. In this regard, a large number of microsensors for almost every possible sensing modality have been de- veloped, including pressure, inertial forces, chemical species, magnetic fields, etc. Accordingly to this, MEMS can be found today in many real applications across multiple markets, such as automotive, consumer, defense, industrial, medical, telecommunications, etc. The main advantages for the use of MEMS in front of other classical technologies are small size, low cost, high isolation and low power consumption. However, there are still some reliability issues hindering the use of MEMS devices in some applications. Mechanical and electrical phenomena involving such micro-scale structures have been matter of study during the last years, being dielectric charging the most important in the case of electrostatically actuated MEMS. The charge accumulated in dielectric layers has a significant impact on the behavior of such devices by altering the electric field distribution in the structure and causing some undesirable effects such as shifts of the Capacitance-Voltage (C-V) characteristic and even permanent stiction of movable mechanical parts, so that the device becomes permanently damaged. Thus, detection and control of dielectric charge are of capital importance due to their strong influence on device performance and reliability. In order to face this challenge, in this Thesis dielectric charge phenomena have been studied under bipolar voltage actuation and several different control strategies have been proposed. These control schemes have demonstrated to be useful to set the dielectric charge to a desired level for contactless MEMS such as varactors, electrostatic positioners or microphone MEMS. Furthermore, these methods have provided the first active compensation of charge trapping generated by ionizing radiation in any device. The first approach to control trapped charge proposed consisted in alternating voltage polarity, depending on the sampled value of the device capacitance. This method demonstrated the feasibility of compensating horizontal shifts of the C-V by charge injection while paving the way for the second control proposed. For the implementation of this second method, which was later patented worldwide, two voltage waveforms were introduced for both monitoring and controlling the net trapping charge. This method resulted in a true sigma-delta modulator capable of providing control for both signs of net trapped charge. Finally, two further methods were proposed which improved the performance of the second control. The first one implemented a second-order sigma-delta control and the last one introduced some modifications in the feedback loop to allow continuous capacitance control while dielectric charge is being also controlled.
Los sistemas micro-electromecánicos, conocidos como MEMS, constituyen una alternativa tecnologíca que ha experimentado un gran crecimiento en las últimas décadas. Desde que en 1959, cuando el físico teórico Richard Feynman introdujo el concepto de nanotecnología en su famosa conferencia "There is plenty of room at the bottom", multitud de investigadores y empresas se han dedicado al desarrollo y la mejora permanente de este tipo de dispositivos. Las principales ventajas del uso de MEMS frente otras tecnologías más clásicas radican en su menor tamaño, su reducido coste y su bajo consumo. En tanto MEMS se refiere habitualmente a tecnologías micrométricaa de dispositivos que presentan partes móbiles, éstos son extensamente utilizados en aplicaciones tanto de detección como de actuación. Así, se ha desarrollado un gran número de microsensores MEMS, cubriendo prácticamente todas las modalidades de detección, incluyendo presión, fuerzas inerciales, sustancias químicas, campos magnéticos, etc. Hoy en día, se utilizan dispositivos MEMS en aplicaciones de mercados como automoción, industria, medicina, telecomunicaciones, defensa, etc. Sin embargo, existen aún problemas de fiabilidad que limitan el uso de los MEMS en determinadas aplicaciones. Los fenómenos mecánicos y eléctricos que se producen en estas estructuras micrométricas han sido objeto de estudio durante los últimos años, siendo el más destacado el producido por la carga eléctrica acumulada en las capas dieléctricas que forman parte de los MEMS actuados electrostáticamente. Esta acumulación de carga altera la distribución de campo eléctrico en el dispositivo, afectando el comportamiento y las prestaciones de éste y causando efectos no deseados, como desplazamientos de la característica Capacidad-Tensión (C-V) e incluso colapsos indeseados de las partes móviles, que pueden conllevar daños permanentes. En consecuencia, la detección y el control de la carga acumulada en dieléctricos de MEMS son temas de vital importancia, debido a su enorme impacto en el rendimiento y la fiabilidad de los dispositivos. Esta Tesis aborda este desafío, primero estudiando y modelizando la dinámica de la acumulación de carga dieléctrica cuando el dispositivo se actúa con tensiones bipolares, y, a continuación, proponiendo y evaluando estrategias de control de dicha carga. Se han demostrado estrategias que, por primera vez, permiten mantener un nivel de carga prefijado en dispositivos MEMS que operan en estado abierto, como varactores, posicionadores electrostáticos o micrófonos MEMS. Además, estos controles han permitido realizar la primera demostración de compensación activa de carga generada por radiaciones ionizantes en dispositivos MEMS. El primer control propuesto consistía en alternar la polaridad de la tensión de actuación, dependiendo del valor de capacidad del dispositivo medido periódicamente. Con el uso de este método se demostró la factibilidad de compensar desplazamientos horizontales de la C-V mediante la inyección de carga debida a la actuación y se abrió el camino para la concepción de un segundo método mejorado. Para la implementación de este segundo método, que fue patentado más tarde, se propusieron dos formas de onda para actuar el dispositivo, que permiten tanto la monitorización como el control de la carga atrapada. Este método se basa en la modulación sigma-delta de primer orden y permite, por primera vez, controlar la carga neta atrapada en el dieléctrico. Finalmente, se han propuesto dos métodos de control más, con el objetivo de introducir mejoras sobre los ya comentados. El primero de ellos implementa una modulación sigma-delta de segundo orden, mientras que en el segundo se introducen algunas modificaciones en el lazo de ralimentación que permiten el control de la capacidad del dispositivo al mismo tiempo que el control de la carga neta atrapada.

Abstract:
Contactless Electric Vehicle (EV) charging based on magnetic resonant induction is an emerging technology that can revolutionize the future of the EV industry and transportation systems by enabling an automated and convenient charging process. However, in order to make this technology an acceptable alternative for conventional plug-in charging systems it needs to be optimized for different design measures. Specifically, the efficiency of an inductive EV charging system is of a great importance and should be comparable to the efficiency of conventional plug-in EV chargers. The aim of this study is to develop solutions that contribute to the design enhancement of inductive EV charging systems. Specifically, generalized physics-based design optimization methods that address the trade-off problem between several key objectives including efficiency, power density, misalignment tolerance, and cost efficiency considering critical constraints are developed. Using the developed design methodology, a 3.7kW inductive charging system with square magnetic structures is investigated as a case study and a prototype is built to validate the optimization results. The developed prototype achieves 93.65% efficiency (DC-to-DC) and a power density of 1.65kW/dm3. Also, self-tuning power transfer control methods with resonance frequency tracking capability and bidirectional power transfer control are presented. The proposed control methods enhance the efficiency of power converters and reduce the Electromagnetic Interference (EMI) by enabling soft-switching operations. Several simplified digital controllers are developed and experimentally implemented. The controllers are implemented without the use of DSP/FPGA solutions. Experimental tests show that of the developed simplified controllers can effectively regulate the power transfer around the desired value. Moreover, the experiments show that compared to conventional converters, the developed converters can achieve 4% higher efficiency at low power levels. Moreover, enhanced matrix converter topologies that can achieve bidirectional power transfer and high efficiency with a reduced number of switching elements are introduced. The self-tuning controllers are utilized to design and develop control schemes for bidirectional power transfer regulation. The simulation analyses and experimental results show that the developed matrix converters can effectively establish bidirectional power transfer at the desired power levels with soft-switching operations and resonance frequency tracking capability. Specifically, a direct three-phase AC-AC matrix converter with a reduced number of switches (only seven) is developed and built. It is shown that the developed converters can achieve efficiencies as high as 98.54% at high power levels and outperform conventional two-stage converters.

Abstract:
In an industrial society it is critical that techniques be developed for the measurement of chemical species in the environment, in humans and as both intended and unintended products of manufacturing. Initially, these techniques were developed around sophisticated instruments and often involved complex procedures. It is obviously advantageous if the cost of analyses can be reduced and the experimental procedures simplified, while still maintaining the quality of the data collected. Furthermore, it is often desirable to have measurements performed rapidly, with on-site measurement sometimes deemed useful or even essential. All of these desirable outcomes may, in some cases, be obtained by miniaturisation. The interest in miniaturisation has led to rapid growth of the field of microfluidics, an area of study which involves using small volumes of liquids, often with detection systems specifically tailored to these reduced volumes. Microfluidic systems must have some way of moving liquids through various stages of chemical or physical processes. One particularly interesting pumping method involves the use of centrifugal force, which eliminates the need for pumps and minimises connections to the platform on which the analysis is done. Up to this point, centrifugal systems have generally been constrained to a limited number of sequential analytical steps as liquid could only flow in the direction demanded by the applied centrifugal force.In this thesis, a variety of liquid manipulation techniques on centrifugal microfluidic platforms were developed and characterised. These techniques were used to miniaturise standard classical analytical methods and implement them on centrifugal microfluidic platforms with the goal of monitoring environmentally important compounds such as aqueous sulfide. A two-phase liquid displacement pumping technique and a pneumatic-centrifugal pumping technique are demonstrated and presented. The developed pneumatic-centrifugal system was used to significantly increase the toolbox of capabilities for centrifugal microfluidic platforms, simultaneously enabling critical microfluidic operations such as valveless liquid transfer, metering, liquid flow switching, agitative micromixing, and liquid recirculation. This technique is based on contactless implementation of pneumatic pressure using compressed air on a continually rotating centrifugal microfluidic platform, thereby enabling complete liquid flow control by combining the effects of pneumatic pressure and centrifugal force.This new type of pneumatically enhanced centrifugal microfluidic platform greatly simplifies the fabrication process by minimising valving requirements, as well as improving efficiency by performing analyses in a highly automated manner. The pneumatic approach was applied to an on-disk calibration and spectrophotometric measurement using the method of standard additions. Similarly, another pneumatically enhanced platform was developed for performing liquid-liquid extractions between an aqueous phase and an organic phase, demonstrating that these centrifugal platforms are not only capable of performing complex multi-step reactions, but also multi-cycle reactions and processes. Finally, an application-specific pneumatically enhanced centrifugal platform was developed for the spectrophotometric determination of aqueous hydrogen sulfide.All of the developed analytical methods only required small sample and reagent volumes, are highly automated and convenient, and have the potential to be performed in a field environment without the need for highly trained personnel.
Dans notre société industrielle, la conception de techniques pour la quantification d'espèces chimiques dans l'environnement, les humains et les dérivés de la production manufacturière est primordiale. Au départ, ces techniques avaient été élaborées à partir d'instruments sophistiqués et se basaient sur des procédures complexes. Il serait donc avantageux de pouvoir réduire les coûts d'analyse et simplifier les procédures expérimentales, tout en maintenant un niveau élevé de la qualité des données recueillies. De plus, il est souvent souhaitable de pouvoir effectuer ces mesures rapidement, et si possible sur le site où l'échantillon à analyser est recueilli. Toutes ces caractéristiques bénéfiques des méthodes analytiques peuvent être obtenues, dans certains cas, à travers la miniaturisation. L'intérêt pour la miniaturisation a mené à une croissance rapide des systèmes microfluidiques, un domaine d'études qui se concentre sur l'utilisation de petits volumes de liquide et des systèmes de détection spécialement adaptés à ces volumes réduits. Tout système microfluidique doit intégrer une méthode de transfert des liquides à travers différentes étapes de traitements chimiques ou physiques. Une méthode de pompage particulièrement intéressante utilise la force centrifuge, ce qui permet d'éliminer l'utilisation de pompes ou connections externes au système où s'effectue l'analyse chimique. Jusqu'à présent, les systèmes employant la force centrifuge ont été limités par le nombre d'étapes analytiques consécutives, le liquide ne pouvant se déplacer que dans une seule direction définie par la force centrifuge appliquée.Pour cette thèse, plusieurs techniques de manipulation des liquides sur un système microfluidique à base de force centrifuge ont été dévelopées et caractérisées. Ces techniques ont été utilisées pour miniaturiser les méthodes analytiques classiques pour ensuite les intégrer à des plateformes microfluidiques à base de force centrifuge, l'objectif final étant la surveillance d'espèces chimiques dans l'environnement. Une technique de pompage par déplacement de deux phases liquides et une technique de pompage pneumatique à base de force centrifuge sont démontrées. La technique pneumatique à base de force centrifuge qui a été développée augmente de façon significative les capacités de la boîte à outils des systèmes microfluidiques à base de force centrifuge. Ce nouveau système permet d'effectuer simultanément des opérations essentielles dans les systèmes microfluidiques telles que le transfert de liquides sans valves, les dosages, la commutation du débit des liquides, les micromélanges par agitation ainsi que la recirculation des liquides. Cette technique se base sur l'application sans contact d'une pression pneumatique en utilisant de l'air comprimé sur un système microfluidique à base de force centrifuge en rotation constante. Ceci permet un contrôle complet du débit des liquides en combinant les effets de la pression pneumatique et de la force centrifuge. Le processus de fabrication de ce nouveau système est grandement simplifié par l'ajout du système pneumatique car cela diminue le nombre de valves à intégrer dans le système. De plus, son efficacité est accrue grâce à la possibilité d'effectuer des analyses de façon automatisée. Cette approche pneumatique a été appliquée à des mesures spectrophotométriques par la méthode des additions connues effectuées directement sur le disque. Dans le même ordre d'idées, un autre système employant la fonction pneumatique a été développé pour effectuer des extractions liquide-liquide entre une phase liquide et une phase organique. Ceci a démontré que la plateforme centrifuge est capable non seulement d'effectuer des réactions chimiques complexes en plusieurs étapes, mais aussi de répéter les cycles de réactions et autres processus.

Abstract:
In questa tesi si mostra come un motore a induzione di tipo doubly fed (DFIM) possa assolvere contemporaneamente le funzioni di motore e di trasmissione di potenza In particolare questa peculiarità è particolarmente utile laddove sia necessario alimentare dei dispositivi elettrici a bordo di una macchina automatica a giostra, normalmente alimentati tramite contatti striscianti: da quest’ultimi infatti spesso derivano innumerevoli problematiche di usura e sicurezza. In particolare, in questa tesi verrà trattato un azionamento pentafase: tale scelta è stata dettata dalla possibilità di disaccoppiare la trasmissione di potenza elettrica e quella meccanica. Data la particolarità di tale macchina una lunga sezione è dedicata alla sua descrizione. Si presentano tre diverse metodologie di funzionamento e controllo della macchina doubly fed: in particolare le prime due, che si avvalgono di modulazioni di coppia o di potenza, potrebbero essere implementate anche su un motore trifase qualora risultasse conveniente; al contrario l’ultimo controllo proposto, che si fonda sull’utilizzo indipendente delle frequenze di statore, è applicabile solo a un DFIM pentafase. Dai risultati ottenuti in simulazione, ma comprendenti moltissimi gradi di realismo, appare evidente come quest’ultimo dia i risultati migliori e sfrutti al meglio la macchina pentafase.

Abstract:
Manufacturing industry works on Overall Equipment Effectiveness (OEE) to increase the yield and speed of machining. A good knowledge of the machine properties is important to increase the speed while still maintaining stable cutting with low tool usage.To make models of the machine is therefore important and in machining a common way to extract the dynamic properties is frequency response measurement. One way is to use an impact hammer to excite the machine tool and measure the response. The problem is that a hammer can only be used on a non running machine. At Manufacturing and Metrology Systems division at KTH (MMS) a test method for contactless excitation has been developed that uses electromagnets to excite the machine tool. By using contactless testing it can be used on rotating machine tools without real cutting in materials. In this thesis a new test system for the contact less testing method has been designed and constructed to test if it is possible to do test on a bigger variety of rotating cutting machine tools. The results for the prototype is presented and evaluated.
Dagens tillverkningsindustri arbetar för att utrsutningens totala effiktivitet ska höjas genomatt öka hastigheten och minska material- och verktygsanvändningen vid bearbetningen utan att minska kvalitén på slutprodukten. För att öka hastigheten krävs en god kännedom om maskinens egenskaper för att maskinen ska arbeta under stabila förhållanden där också verktygets slitage minskas. Att ta fram modeller över maskinen är därför viktigt och inom skärande bearbetning är frekvensresponsmätning ett sätt att få ut de dynamiska egenskaperna av det skärandeverktyget. En vanlig testmetod är att med en hammare exitera verktyget och mäta responsen. Problemet är dock att hammaren bara kan mäta vid stillastående maskin. Vid MMS har en testmetod för kontaktlös exitering tagits fram där elektromagneter användsför exiteringen. På så sätt kan testet utföras på roterande verktyg utan att man behöver förbruka material. I detta arbete har ett nytt testsystem för denna testmetod designats och konstruerats för att testa om det är möjligt med testning på flera storlekar på maskiner för skärandebearbetning. Resultaten för prototypen presenteras och utvärderas.

We study first how tomodel the magnetic field created by an electromagnet. We develop an analytical modeltaking into account the ferromagnetic core of electromagnets. Then, we study a genericsystem composed of n electromagnets which can move throughout space. We develop amodel of the system, integrating the mobility of each of the electromagnets. This modelis then linearized, allowing us to introduce a linearizing control. This command allowsindependent management of the movement of each of the electromagnets, and the currentflowing in it. Finally, the model and the command are tested in simulation and on anexperimental device.Keywords: Magnetism

Abstract:
Comprehensive knowledge and information about the static and dynamic behaviour of machine tools, cutting processes and their interaction is essential for machining system design, simulation, control and robust operation in safe conditions. The very complex system of a machine tool, fixture and cutting tools during the machining of a part is almost impossible to model analytically with sufficient accuracy. In combination with increasing demands for precision and efficiency in machining call for new control strategies for machining systems. These strategies need to be based on the identification of the static and dynamic stability under both the operational and off-operational conditions. To achieve this it is necessary to monitor and analyze the real system at the factory floor in full production. Design information and operational data can then be linked together to make a realistic digital model of a given machining system. Information from such a model can then be used as input in machining simulation software to find the root causes of instability. The work presented in this thesis deals with the static and dynamic capability of machining systems. The main focus is on the operational stability of the machining system and structural behaviour of only the machine tool, as well. When the accuracy of a machining system is measured by traditional techniques, effects from neither the static stiffness nor the cutting process are taken into account. This limits the applicability of these techniques for realistic evaluation of a machining system’s accuracy. The research presented in this thesis takes a different approach by introducing the concept of operational dynamic parameters. The concept of operational dynamic parameters entails an interaction between the structural elements of the machining systems and the process parameters. According to this concept, the absolute criterion of damping is used to evaluate the dynamic behaviour of a machining system. In contrast to the traditional theory, this methodology allows to determine the machining system's dynamic stability, in real time under operating conditions. This framework also includes an evaluation of the static deformations of a machine tool.  In this context, a novel concept of elastically linked system is introduced to account for the representation of the cutting force trough an elastic link that closes the force loop. In addition to the elastic link which behaves as a static element, a dynamic non-contact link has been introduced. The purpose is to study the non-linear effects introduced by variations of contact conditions in joints due to rotational speed.
