书籍 UMTS+Performance+Measurement+A+Practical+Guide
Having dealt with in-depth analysis of SS#7, GSM and GPRS networks I started to monitor
UTRAN interfaces approximately four years ago. Monitoring interfaces means decoding
the data captured on the links and analysing how the different data segments and messages
are related to each other. In general ...
书籍 Wireless+Communications+Algorithmic+Techniques
Digital radios have undergone an astonishing evolution in the last century. Born as a set of simple and
power-hungry electrical and electromechanical devices for low data rate transmission of telegraph data
in the Marconi age, they have transformed, thanks to substantial advances in electronic techn ...
书籍 DSP in Power Electronics Control Circuits
The first edition of the book was one of the elements of my habilitation (a quali-
fication above a Ph.D., which is a necessary step for obtaining the title of a
professor in Poland and other European countries), and as a result it was subse-
quently very carefully reviewed by four reviewers. The ha ...
书籍 Field_Geophysics
The purpose of this book is to help anyone involved in small-scale geophys-
ical surveys. It is not a textbook in the traditional sense, in that it is designed
for use in the field and concerns itself with practical matters – with the-
ory taking second place. Where theory determines field practice ...
书籍 DRM023_3-Phase AC Designer Reference Manual
This reference design describes the design of a 3-phase AC induction
vector control drive with position encoder coupled to the motor shaft. It
is based on Motorola’s DSP56F805 dedicated motor control device.
AC induction motors, which contain a cage, are very popular in variable
speed drives. They ...

技术资料 电动汽车永磁无刷直流电机控制器设计
对某四轮独立驱动电动汽车轮毂电机进行研究,设计一种永磁无刷直流电机控制器.以STM32F103RBT6芯片为基础,对电机驱动电路、采样电路和保护电路分别进行硬件设计与分析;同时,采用模块化软件设计方案,对该控制器的软件系统进行升级.实验验证表明:所设计的电机控制器能使电机响应迅速、转速稳定、无超调,且电动车动力输出性能良 ...
技术资料 基于STM32的智能小车四轮驱动控制系统设计
在传统智能小车驱动电路设计中,较多考虑使用直流电机还是步进电机,电机功率、能耗等性能参数。使用具有armCortexM4内核的STM32嵌入式平台控制四轮的4个直流电机。文章基于PWM技术及PID算法,对四轮进行精准地速度、转向及启停控制,实验表明此小车具有优越各种地形适应能力。In the traditional intelligent car drive circui ...
技术资料 高精度双向DC电源电流采样电路设计
为适应双向DC/DC功率变换的电流采样需求,一种高精度高边电流采样电路被提出。其基本思想是在功率电路的高边串入采样电阻,借助电流镜原理并引入偏置电流电路,将双向电流均转换为正向电压输出。通过理论分析与仿真结合的方法对电流镜采样原理及4种不同的偏置电流电路方案进行对比,最后通过实验数据验证了高精度高边电流采样电 ...
技术资料 模型预测控制外文教程
这是一本英文版的MPC的MATLAB教程，讲这一块的资料太少了，故上传一本。MPC is one of the few areas that has received on-going interest from researchers in both the industrial and cademic communities.Four major aspects of model predictive control make the design methodology attractive to both practi ...
