  • Linear_Matrix_Inequalities_in_System

    The basic topic of this book is solving problems from system and control theory using convex optimization. We show that a wide variety of problems arising in system and control theory can be reduced to a handful of standard convex and quasiconvex optimization problems that involve matrix inequalities. For a few special cases there are “analytic solutions” to these problems, but our main point is that they can be solved numerically in all cases. These standard problems can be solved in polynomial- time (by, e.g., the ellipsoid algorithm of Shor, Nemirovskii, and Yudin), and so are tractable, at least in a theoretical sense. Recently developed interior-point methods for these standard problems have been found to be extremely efficient in practice. Therefore, we consider the original problems from system and control theory as solved.

  • MultivariableControlSystems

    This introductory chapter is devoted to reviewing the fundamental ideas of control from a multivariable point of view. In some cases, the mathematics and operations on systems (modelling, pole placement, etc.), as previously treated in introductory courses and textbooks, convey to the readers an un- realistic image of systems engineering. The simplifying assumptions, simple examples and “perfect” model set-up usually used in these scenarios present the control problem as a pure mathematical problem, sometimes losing the physical meaning of the involved concepts and operations. We try to empha- sise the engineering implication of some of these concepts and, before entering into a detailed treatment of the different topics, a general qualitative overview is provided in this chapter.

  • Computational+Intelligence

    The large-scale deployment of the smart grid (SG) paradigm could play a strategic role in supporting the evolution of conventional electrical grids toward active, flexible and self- healing web energy networks composed of distributed and cooperative energy resources. From a conceptual point of view, the SG is the convergence of information and operational technologies applied to the electric grid, providing sustainable options to customers and improved security. Advances in research on SGs could increase the efficiency of modern electrical power systems by: (i) supporting the massive penetration of small-scale distributed and dispersed generators; (ii) facilitating the integration of pervasive synchronized metering systems; (iii) improving the interaction and cooperation between the network components; and (iv) allowing the wider deployment of self-healing and proactive control/protection paradigms.

  • 音频放大器设计

    This design uses Common-Emitter Amplifier (Class A) with 2N3904 Bipolar Junction Transistor. Use “Voltage Divider Biasing” to reduce the effects of varying β (= ic / ib) (by holding the Base voltage constant)  Base Voltage (Vb) = Vcc * [R2 / (R1 + R2)]  Use Coupling Capacitors to separate the AC signals from the DC biasing voltage (which only pass AC signals and block any DC component).  Use Bypass Capacitor to maintain the Q-point stability.  To determine the value of each component, first set Q-point close to the center position of the load line. (RL is the resistance of the speaker.)

  • CPU可测试性设计

    可测试性设计(Design-For-Testability,DFT)已经成为芯片设计中不可或缺的重要组成部分。它通过在芯片的逻辑设计中加入测试逻辑提高芯片的可测试性。在高性能通用 CPU 的设计中,可测试性设计技术得到了广泛的应用。本文结合几款流行的 CPU,综述了可应用于通用 CPU 等高性能芯片设计中的各种可测试性方法,包括扫描设计(Scan Design),内建自测试(Built-In Self-Test,BIST),测试点插入(Test Point Insertion),与 IEEE 1149.1标准兼容的边界扫描设计(Boundary Scan Design,BSD)等技术。

  • 高清电子书-C++ Primer Plus 第6版英文版 1438页

    高清电子书-C++ Primer Plus, 第6版英文版 1438页Learning C++ is an adventure of discovery, particularly because the language accommodates several programming paradigms, including object-oriented programming, generic programming, and the traditional procedural programming.The fifth edition of this book described the language as set forth in the ISO C++ standards, informally known as C++99 and C++03, or, sometimes as C++99/03. (The 2003 version was largely a technical correction to the 1999 standard and didn’t add any new features.) Since then, C++ continues to evolve.As this book is written, the international C++ Standards Committee has just approved a new version of the standard.This standard had the informal name of C++0x while in development, and now it will be known as C++11. Most contemporary compilers support C++99/03 quite well, and most of the examples in this book comply with that standard. But many features of the new standard already have appeared in some implementations, and this edition of C++ Primer Plus explores these new features. C++ Primer Plus discusses the basic C language and presents C++ features, making this book self-contained. It presents C++ fundamentals and illustrates them with short, to-the-point programs that are easy to copy and experiment with.You learn about input/output (I/O), how to make programs perform repetitive tasks and make choices, the many ways to handle data, and how to use functions.You learn about the many features C++ has added to C, including the followi
