PERMODELAN KONVERTER BOOST MULTILEVEL DENGAN KONTROL PID ANALOG SEBAGAI CATU DAYA MOBIL LISTRIK

Mobil listrik memanfaatkan motor listrik sebagai penggerak. Penggerak yang digunakan adalah motor DC, karena motor DC itu lebih mudah untuk diatur kecepatannya dari pada motor AC. Jenis konverter daya yang digunakan dalam aplikasi penggerak mobil listrik ini adalah konverter boost. Konverter boost adalah pengkonversi nilai tegangan masukan menjadi lebih tinggi sehingga nilai tegangan keluaran sesuai dengan yang dibutuhkan oleh beban. Konverter boost ini sering digunakan untuk mencatu daya motor listrik. Dan untuk menjadi catu daya motor listrik diperlukan tegangan keluaran yang stabil. Pada skripsi ini menjelaskan proses kerja konverter boost dengan topologi konverter boost multilevel pada mobil listrik menggunakan simulasi software dan permodelan alat. Dan pada skripsi ini pun menjelaskan cara membuat tegangan keluaran stabil dengan kontrol PID. Kontrol PID tersebut menggunakan IC TL494. Dengan menggunakan data beban motor DC produksi MIKI PULLEY maka ditargetkan konverter boost multilevel memiliki tegangan keluaran yang stabil sebesar 200 volt dan arus keluran mampu hingga 6 ampere. Saat penelitian menggunakan simulasi, keluaran dari konverter boost multilevel berhasil mencapai target. Saat pengujian dengan permodelan, keluaran dari konverter boost multilevel berhasil 200 volt tetapi stabil hingga 0,1 ampere. Hal ini dikarenakan ada komponen pada konverter boost multilevel yang menghambat pada proses pengujian, yaitu induktor. Induktor yang digunakan adalah toroid dengan kawat 0,7mm.;--- Electric car utilizing the electric motor as the driving. The electric motor used is a DC motor, because DC motors is easier to set the speed than the AC motor. Types of power converters used in electric car propulsion applications are boost converter. Boost converter is the converter input voltage value becomes higher so that the value of the output voltage as required by the load. The boost converter is often used to supplied power of electric motors. And to be a necessary electric motor power supply, the output voltage must be stable. In this thesis describes the process of working the boost converter with multilevel boost converters topologies in electric cars using a simulation software and modeling tools. And in this thesis also describes how to create a stable output voltage with PID control. The PID control using TL494 IC. Using data load MIKI PULLEY DC motor production then targeted multilevel boost converters have a stable output voltage of 200 volts and currents load capable of up to 6 amperes. When studies using the simulation, the output of the boost converter multilevel managed to hit the target. When testing with the modeling tools, the output of the boost converter multilevel managed 200 volts but stable to 0.1 ampere. This is because there is a component in the multilevel boost converter that inhibits the testing process, namely the inductor. Toroid inductor is used with 0,7mm wire

Delivering Honeypots as a Service

The effect of honeypots in slowing down attacks and collecting their signatures is well-known. Despite their known effectiveness, these technologies have remained underutilized, especially by small and medium-sized enterprises, because internal hosting and configuration of honeypots requires extensive expertise and infrastructure, which is unjustifiably expensive especially for small or medium-sized enterprises. In this paper, we propose a novel security approach that enables a security service provider to offer honeypot-as-a-service (HaaS) to customer enterprises. The HaaS service is offered by a plug-and-play gateway and incorporates a network of moving high-interaction honeypots into unused address space of client enterprises. These honeypots are configured tailored to the mission and type of services offered by the customer enterprise to blend in the surrounding network for maximum believability while looking vulnerable enough to engage potential attackers. As a contribution, we formulate and solve the problem of strategic configuration planning of a group of honeypots for a given input network. We also provide the necessary infrastructure and mechanisms for realizing the model and offering it to client enterprises without affecting their regular operations. Using experimental and analytical modeling, we evaluate our approach and show its robustness against honeypot mapping attacks, and its effectiveness in slowing down large-scale cyber intrusion attacks on enterprise networks

A Deception Planning Framework for Cyber Defense

The role and significance of deception systems such as honeypots for slowing down attacks and collecting their signatures are well-known. However, the focus has primarily been on developing individual deception systems, and very few works have focused on developing strategies for a synergistic and strategic combination of these systems to achieve more ambitious deception goals. The objective of this paper is to lay a scientific foundation for cyber deception planning, by (1) presenting a formal deception logic for modeling cyber deception, and (2) introducing a deception framework that augments this formal modeling with necessary quantitative reasoning tools to generate coordinated deception plans. To show expressiveness and evaluate effectiveness and overhead of the framework, we use it to model and solve two important deception planning problems: (1) strategic honeypot planning, and (2) deception planning against route identification. Through these case studies, we show that the generated deception plans are highly effective and outperform alternative random and unplanned deception strategies

Molecular Mechanics Simulations Of Quartz Etching Process

In this thesis, the physical etching of argon bombardment onto α-quartz and amorphous quartz substrates were studied and investigated using molecular mechanics methods. Although there are extensive studies on quartz etching, larger numbers of the research are experimental and the studies focus on the process outcomes rather than the fundamental study of the process. Molecular mechanics methods such as Monte Carlo (MC) method and Molecular Dynamics (MD) method enables researchers in building the model from ground up to the physical etching process. This kind of bottom-up design allows us to study the process in molecular level and help researcher grasp the fundamental theory of the process. Two computational methods have been employed in order to study quartz etching process. The first method are based on statistical approach i.e Monte Carlo and the second method is based on deterministic approach i.e Molecular Dynamics. In Monte Carlo method, the main interest of the simulations is sputtering yield, Ys and energy distribution of sputtered atoms. The relationship of incident energy, Ei , and incident angle θi to the interested subjects will also been investigated and discussed. It was found that at incident angle θi =70⁰ at any incident energy, Ei, the sputtering yield, Ys is maximum. Molecular Dynamics method reported the effect of etching selectivity, the effect of substrate temperature, Ts, and the effect of incident energy, Ei to the sputtering yield and ultimately corroborates the factor and sputtering yield with the properties of the substrate. The main objective of this project is to use computational method (i.e Molecular Dynamics) to model the process at the scale of molecular level. Two difference substrates (amorphous and α-quartz) are subjected to a range of incident energy. Ei and temperature, Ts and the sputtering yield were studied. Morse potential and Second Generation Charge-Optimized Many Body (COMB) potentials were utilised as the inter-atomic potential. α-quartz shows higher sputtering yield as compared to amorphous quartz at any given incident energy, Ei and substrate temperature, Ts. α-quartz has also produced more stoichiometric yield compared to amorphous quartz. This is because for α quartz, the sputtered product are in mostly the form of SiO2 molecule while amorphous substrate the sputtered product in the form of atom. Incident enery, Ei gave significant increase in the sputtering yield compared to temperature, Ts. In this thesis, the computational model of physical etching on quartz has been demonstrated using the Monte Carlo (MC) method and Molecular Dynamics (MD) method. Several factors are studied and better understandings of the process in molecular level have been achieved. The results of this study could be applied in 2D and 3D patterning used in lithography techniqu
