  • Web Based Enterprise Energy

    HIS IS THE THIRD —and most likely the last—book in the series on information technology for energy managers and web based energy infor- mation and control systems. This book concentrates on web based enterprise energy and building automation systems, and serves as a capstone volume in this series. The thrust here is that the highest level functions of a building and facility automation system are provided by a web based EIS/ECS system that provides energy management, maintenance management, overall facility operational management, and ties in with the enterprise resource management system for the entire facility or the group of facilities being managed. If there were ever to be a fourth volume in this series, it would follow the logical progression of the first three volumes, and would probably be titled Web Based Enterprise Resource Management Systems.

  • Risk-Based+Maintenance+for+Electricity+Network

    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.

  • A_Software-Defined_GPS_and_Galileo_Receiver

    Software-defined radios (SDRs) have been around for more than a decade. The first complete Global Positioning System (GPS) implementation was described by Dennis Akos in 1997. Since then several research groups have presented their contributions. We therefore find it timely to publish an up-to-date text on the sub- ject and at the same time include Galileo, the forthcoming European satellite- based navigation system. Both GPS and Galileo belong to the category of Global Navigation Satellite Systems (GNSS).

  • 基于DSP28035的高速永磁无刷直流电机驱动系统

    基于DSP28035的高速永磁无刷直流电机驱动系统,包括论文和软硬设计资料。摘要参赛作品为基于DSP28035的高速永磁无刷直流电机驱动系统。该系统以一台额定转速60 krpm的高速永磁无刷直流电机、交错并联的Buck电路以及全桥电路为硬件平台,以DSP28035为控制核心,实现了调压调速功能和基于坐标变换的无位置传感器新技术。为实现该系统要求,本作品充分利用了DSP28035的资源例如:CLA模块,模拟比较器、HPWM模块以及AD转换模块等。AbstractThis work is the drive system for a high speed permanent magnet burshless dc motor based on DSP28035. The hardware platform consists of a BLDC motor(rated speed is 60000rpm), a Buck circuit and an inverter. Under the control of DSP28035, this system can achieve the goal of adjusting the motor’s speed with voltage and the function of sensorless control based on the coordinate transformation. By making full use of resources of the core, such as CLA, analog comparator, HPWM and AD converters, the whole system can meet the requirements.1 引言高速永磁无刷直流电机驱动系统由于基波频率较高(一般在1kHZ以上),利用逆变桥斩波进行调速的控制方式通常会受到开关管开关频率的限制,因此该系统多采用三相全桥前级加Buck电路进承担调压调速的功能,而三相全桥主要承担逻辑换相的功能。然而,传统Buck电路所需电感的体积较大,增加了系统的体积,降低了系统的功率密度。

  • 基于TMS320F28035芯片为控制核心的空间矢量异步电机变频器

    基于TMS320F28035芯片为控制核心的空间矢量异步电机变频器  我们设计的异步电机变频调速器以TMS320F28035芯片为控制核心,通过输出三相PWM波控制智能功率模块IPM驱动三相异步电机。我们使用空间矢量SVPWM算法,并对其进行了优化。采用检测反电势的方法省去了昂贵的光电编码器,大大节省了成本。同时开创性的研发了自动根据运行环境调节的自适应变频算法,使我们的变频调速器可以在电网条件恶劣的乡村山区工作,由此该变频器已被一家民用水泵生产企业预订。关键字 变频器 TMS320f28035 IPM SVPWM In our design, the asynchronous machine inverter based on the chip of TMS320F28035 drives the three-Phase asynchronous machine by sending three-phase PWM waves to the IPM, which is short for the Intelligent-Power-Module. The SVPWM (space vector pulse width modulation) strategy is applied to our control algorithm and we optimize it mainly in two aspects. Firstly the inverter detects the speed by measuring the Back EMF instead of installing an expensive photoelectric encoder for costs reduction.
