This book is based on a Ph.D. research that has been conducted at the Delft
UNIVERSITY of Technology in the Netherlands in collaboration with Dutch Electricity
& Gas Distribution Network Operator, Stedin. This book was written as a result of
wider interest that was shown by different industry groups on this topic after its
public defence. This inspired the author to modify and publish a practical version
of the research for a greater international audience. Therefore, the content of this
book is intended for a double audience, on the one hand for those interested in the
organisational and management aspects of maintenance.
My association with the theory of controls in continuous time started during my studies at
the Indian Institute of Technology, Kharagpur, India, in 1974 as an undergraduate student
in the Controls and Power program. The initial introduction by Professors Kesavamurthy,
Y. P. Singh, and Rajagopalan laid the foundation for a good basic understanding of the
subject matter. This pursuit and further advanced study in the field of digital controls
continued during my days as a graduate student in the Electrical and Systems Engineering
Department at the UNIVERSITY of Connecticut in Storrs, from 1983 to 1988.
This book is an outgrowth of a course developed at Stanford UNIVERSITY over
the past five years. It is suitable as a self-contained textbook for second-level
undergraduates or for first-level graduate students in almost every field that
employs quantitative methods. As prerequisites, it is assumed that the student
may have had a first course in differential equations and a first course in linear
algebra or matrix analysis. These two subjects, however, are reviewed in
Chapters 2 and 3, insofar as they are required for later developments.

We use the internal AD converter to real-time sampling the referenced grid voltage signal, outputting voltage of photovoltaic, feedback outputting voltage and current signal. The PWM module generates SVPWM according to the calculation of the real-time sampling data, to control the full MOSFET inverter bridge output sine wave. We realized that the output voltage of the simulator can track the frequency and phase of the referenced grid voltage with PI regulation, and the maximum photovoltaic power tracking with constant voltage regulation, thereby achieved the purpose of grid-connected simulation. Additionally, this device has the over-voltage and over-current protection, audible and visual alarm, islanding detecting and protection, and it can recover automatically. The testing shows that our design is feasible.Keywords: Photovoltaic Grid-connected，MPPT，DSP 目錄引言 11. 方案論證 11.1. 總體介紹 11.2. 光伏電池模擬裝置 11.3. DC-AC逆變橋 11.4.

針對(duì)目前MSP430單片機(jī)實(shí)驗(yàn)裝置較少、實(shí)驗(yàn)內(nèi)容少,而且無MSP430高端產(chǎn)品的實(shí)驗(yàn)裝置,研制了基于MSP430F5529單片機(jī)的綜合實(shí)驗(yàn)裝置,主要包括MSP430 Launch Pad和母板兩部分。較傳統(tǒng)的單片機(jī)實(shí)驗(yàn)裝置增加了模擬電路的設(shè)置,設(shè)計(jì)的實(shí)驗(yàn)?zāi)軌蚶脝纹瑱C(jī)的所有外設(shè),可進(jìn)行模塊基礎(chǔ)實(shí)驗(yàn)和綜合實(shí)驗(yàn)兩大類實(shí)驗(yàn),非常適合自動(dòng)化和電氣信息類大學(xué)生學(xué)習(xí)使用。Concerning with the lack of experimental equipment and content based on MSP430,and especially,the experimental equipment of MSP430 senior products,an experimental equipment based on MSP430F5529 microcontroller is developed. It mainly consists of two parts： MSP430 Launch Pad and main board. Compared with traditional microcontroller experiment equipment,a few analog circuits were added. The experiment we set up takes advantage of all microcontroller peripherals. Students can do two kinds of experiments： module experiment and complex experiment.Therefore it fits UNIVERSITY students in automation and electrical major very well.
