Description: 外围组件接口技术（Peripheral Component Interconnect PCI）是一种新型的高带宽、处理器无关的总线系统。它既可以作为中间层的总线也可以作为周边总线系统使用。与其他普通总线规范想对照，PCI 总线为高速I/O设备提供了更好的支持（比如图形适配器、网络接口控制器、磁盘控制器，等等）。现行的标准允许在33Mhz下使用64根数据线，纯传输速率可达2.11Gbps。但是PCI吸引人的地方不在于它的高速度，它适应了现代I/O设备对系统的要求，并且只需要很少的芯片就可以实现并支持其他总线系统。-Peripheral Component Interface Technology (Peripheral Component Interconnect PCI) is a new type of high-bandwidth, the processor s bus system has nothing to do. It can serve as a middle layer of the bus can also be used as a peripheral bus system. With other norms would like to control the ordinary bus, PCI bus for high-speed I/O device provides a better support (such as graphics adapters, network interface controllers, disk controllers, etc.). Existing standard to allow 33Mhz using 64 data lines, pure transfer rate up to 2.11Gbps. PCI attractive place but do not lie in its high-speed, it adapted to the modern I/O devices on the system requirements, and require only a few chips can be achieved and to support other bus systems.

Description: This book provides a thorough understanding of the basic principles of power
system frequency behaviour in wide range of operating conditions. It uses simple
frequency response models, control structures and mathematical algorithms to adapt
modern robust control theorems with frequency control issue and conceptual explanations.
Most developed control strategies are examined by real-time simulations.
Practical methods for computer analysis and design are emphasized.
This book emphasizes the physical and engineering aspects of the power system
frequency control design problem, providing a conceptual understanding of
frequency regulation, and application of robust control techniques. The main aim
is to develop an appropriate intuition relative to the robust load frequency regulation
problem in real-world power systems, rather than to describe sophisticated mathematical analytical methods. Platform: |

Description: 步进电机是将电脉冲信号转变为角位移或线位移的开环控制电机，是现代数字程序控制系统中的主要执行元件，应用极为广泛。。在非超载的情况下，电机的转速、停止的位置只取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，当步进驱动器接收到一个脉冲信号，它就驱动步进电机按设定的方向转动一个固定的角度，称为“步距角”，它的旋转是以固定的角度一步一步运行的。可以通过控制脉冲个数来控制角位移量，从而达到准确定位的目的；同时可以通过控制脉冲频率来控制电机转动的速度和加速度，从而达到调速的目的。(Stepper motor is an open loop control motor which transforms electrical pulse signal into angular displacement or linear displacement. It is the main executive element in modern digital control system, and is widely applied. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle, called "step", it is the rotation of the fixed point of the operation step by step. We can control the angular displacement by controlling the number of pulses, so as to achieve the goal of accurate positioning. At the same time, we can control the speed and acceleration of motor rotation by controlling the pulse frequency, so as to achieve the purpose of speed regulation.) Platform: |
