Download or read book Robust Control of DC DC Converters written by Farzin Asadi and published by Springer Nature. This book was released on 2022-05-31 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: DC-DC converters require negative feedback to provide a suitable output voltage or current for the load. Obtaining a stable output voltage or current in the presence of disturbances like input voltage changes and/or output load changes seems impossible without some form of control. This book shows how simple controllers such as Proportional-Integral (PI) can turn into a robust controller by correct selection of its parameters. Kharitonov's theorem is an important tool toward this end. This book consist of two parts. The first part shows how one can obtain the interval plant model of a DC-DC converter. The second part introduces the Kharitonov's theorem. Kharitonov's theorem is an analysis tool rather than a design tool. Some case studies show how it can be used as a design tool. The prerequisite for reading this book is a first course on feedback control theory and power electronics.

Download or read book Modeling Uncertainties in DC DC Converters with MATLAB and PLECS written by Farzin Asadi and published by Springer. This book was released on 2018-11-12 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling is the process of formulating a mathematical description of the system. A model, no matter how detailed, is never a completely accurate representation of a real physical system. A mathematical model is always just an approximation of the true, physical reality of the system dynamics. Uncertainty refers to the differences or errors between model and real systems and whatever methodology is used to present these errors will be called an uncertainty model. Successful robust control-system design would depend on, to a certain extent, an appropriate description of the perturbation considered. Modeling the uncertainties in the switch mode DC-DC converters is an important step in designing robust controllers. This book studies different techniques which can be used to extract the uncertain model of DC-DC converters. Once the uncertain model is extracted, robust control techniques such as ∞ and μ synthesis can be used to design the robust controller. The book composed of two case studies. The first one is a buck converter and the second one is a Zeta converter. MATLAB® programming is used extensively throughout the book. Some sections use PLECS® as well. This book is intended to be guide for both academicians and practicing engineers.

This book was released on 2024-11-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-Robust Control Schemes for Dual-Active-Bridge-Based DC-DC Converter Systems in Renewable Energy Applications is the first book that presents systematic control schemes for multiple DAB-based DC-DC converter systems. The book explores new control methods for various DAB DC-DC converters for high-power applications. These methods include fast-dynamic control, power balance control, soft start-up operation, hot-swap operation, and circuit-parameter estimation. Additionally, the book studies a DAB-based partial power processing DC-DC converter system designed to embed the renewable energy source and the energy storage system for boosting the utilization of components. The book also verifies the dynamic equivalence between the DAB converter and other intermediary inductive AC-link DC-DC converters, which can be helpful in designing control systems for other AC-link-based DC-DC converter systems. This book is a valuable reference for graduate students in electrical engineering, researchers, and power electronics engineers working in manufacturing, renewable energy, and utility industries. In addition, this book: Presents a systematic study of DAB-based converter systems; Highlights new control methods for DAB DC-DC converters for high-power applications; Examines embedding energy sources and storage systems to boost the utilization of renewable energy.

Download or read book Dynamics and Control of DC DC Converters written by Farzin Asadi and published by Morgan & Claypool Publishers. This book was released on 2018-03-08 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: DC-DC converters have many applications in the modern world. They provide the required power to the communication backbones, they are used in digital devices like laptops and cell phones, and they have widespread applications in electric cars, to just name a few. DC-DC converters require negative feedback to provide a suitable output voltage or current for the load. Obtaining a stable output voltage or current in presence of disturbances such as: input voltage changes and/or output load changes seems impossible without some form of control. This book tries to train the art of controller design for DC-DC converters. Chapter 1 introduces the DC-DC converters briefly. It is assumed that the reader has the basic knowledge of DC-DC converter (i.e., a basic course in power electronics). The reader learns the disadvantages of open loop control in Chapter 2. Simulation of DC-DC converters with the aid of Simulink® is discussed in this chapter as well. Extracting the dynamic models of DC-DC converters is studied in Chapter 3. We show how MATLAB® and a software named KUCA can be used to do the cumbersome and error-prone process of modeling automatically. Obtaining the transfer functions using PSIM® is studied as well. These days, softwares are an integral part of engineering sciences. Control engineering is not an exception by any means. Keeping this in mind, we design the controllers using MATLAB® in Chapter 4. Finally, references are provided at the end of each chapter to suggest more information for an interested reader. The intended audiences for this book are practice engineers and academians.

Download or read book Robust Control of Dc dc Boost Converter written by Hisham Mahmood and published by . This book was released on 2008 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this thesis, a robust controller comprising of a PI with phase-lead compensator for a DC-DC boost converter designed using classical frequency response method is presented. The superior performance of this controller in comparison with H ∞ and passivity based integral controllers from the literature is shown. The robustness of the controller to boost converter parameter deviations, disturbance magnitudes and polarity which lead to worst case stability is investigated. This approach offers an alternative to the traditional unstructured uncertainty envelop approach used in the literature. Investigation into the nonlinearity arising from parasitic parameters in a boost converter is also presented in this thesis. It is shown that this nonlinearity can cause instability in boost converter control. This nonlinearity makes robust controller design difficult due to the sensitivity to disturbances. Static and dynamic voltage collapses are then studied. New non-iterative formulae are derived using the bilinear averaged model to calculate the voltage collapse point due to the parasitic parameters. Using these simple formulae boost converter stable operating region and disturbance limits can be calculated in the design phase. The use of these formulae for the design of the boost converter control system is studied. Static characteristics formula and the proposed controller performance are verified experimentally.

This book was released on 2022-06-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computers play an important role in the analyzing and designing of modern DC-DC power converters. This book shows how the widely used analysis techniques of averaging and linearization can be applied to DC-DC converters with the aid of computers. Obtained dynamical equations may then be used for control design. The book is composed of two chapters. Chapter 1 focuses on the extraction of control-to-output transfer function. A second-order converter (a buck converter) and a fourth-order converter (a Zeta converter) are studied as illustrative examples in this chapter. Both ready-to-use software packages, such as PLECS® and MATLAB® programming, are used throught this chapter. The input/output characteristics of DC-DC converters are the object of considerations in Chapter 2. Calculation of input/output impedance is done with the aid of MATLAB® programming in this chapter. The buck, buck-boost, and boost converter are the most popular types of DC-DC converters and used as illustrative examples in this chapter. This book can be a good reference for researchers involved in DC-DC converters dynamics and control.
