backstepping
说明： The objective is to present a nonlinear approach to design a suitable controller system for the photovoltaic (PV) single-phase grid-connected system. The system structure includes a PV generator, Boost converter, and DC-AC inverter coupled to grid network. A backstepping controller is developed to extract maximum point power tracking (MPPT), to regulate the DC bus voltage, and to generate a sinusoidal current into the grid in phase with grid voltage in order to achieve unity power factor. The stability of the control algorithm is demonstrated by tools of Lyapunov analysis. Simulations show that the proposed controller system completely accomplishes listed aims even under atmospheric conditions variation. Theperformance of the proposed controller has been validated by numerical simulation in MATLAB SIMULINK(The objective is to present a nonlinear approach to design a suitable controller system for the photovoltaic (PV) single-phase grid-connected system.

黑客与画家_chinese
本书是硅谷创业之父Paul Graham 的文集，主要介绍黑客即优秀程序员的爱好和动机，讨论黑客成长、黑客对世界的贡献以及编程语言和黑客工作方法等所有对计算机时代感兴趣的人的一些话题。书中的内容不但有助于了解计算机编程的本质、互联网行业的规则，还会帮助读者了解我们这个时代，迫使读者独立思考。
本书适合所有程序员和互联网创业者，也适合一切对计算机行业感兴趣的读者。(This book is the father of the Paul Graham Valley venture anthology, which mainly introduces the hackers good programmers interest and motivation, discussed some topics of interest, the hacker hacker growth contribution to the world as well as the programming language and the working methods of computer hackers all age people. The content of the book will not only help us understand the nature of computer programming, the rules of the Internet industry, but also help readers understand our times, forcing readers to think independently.)
