查询词典 synchronization pulse

Based on accurate step motor system parameters, the state equations describing step motor dynamic characteristics are set up. The operation of the self synchronization closed loop control system is simulated on computer. In the research the principle analysis and system design have been done about self synchronization closed loop operation. The relation between rotating EMF and the rotor position of the step motor is discussed. Through detecting the zero value of rotating EMF the rotor position of the step motor is indirectly obtained.

Secure communication scheme based on chaotic synchronization is an entirely new secure communication scheme. Pecora and Carroll propose secure communication scheme based on chaotic synchronization first in 1990. The scheme makes use of the good characteristic of chaotic signals, and has high security.

In the approach, the synchronization of the chaotic signals between the transmitter and receiver does not rely on the chaotic self-synchronization method proposed by Pecora and Carroll. The chaotic carrier is retrieved by using a non-dynamical system at the receiver which has the same nonlinear function form as what is adopted at the transmitter.

本方法中，收、发两端混沌信号的同步不是依赖于Pecora和Carroll提出的混沌自同步方法，而是在接收端采用一个与发送端具有相同非线性函数形式的非动力学系统从接收信号中提取混沌载波。

For each type of testing, a necessary and sufficient condition is defined, under which a test sequence of an FSM is synchronizable. In this paper a new model—synchroniable digraph is proposed, which can judge whether there exist any synchronizable test sequence for a given specification without synchronization operation, and which can transform its nonsynchronizable test sequence to synchronizable test sequence if the answer is true. A method to judge how to add external synchronization operations in a nonsynchronizable test sequence to change it to synchroniable one is also proposed.

提出了一种新的同步测试序列生成模型——同步有向图，它可以判断一个给定的协议规格是否可以在不需要外部同步操作的情况下，产生同步测试序列；如果可以产生，则此生成模型可以将非同步测试序列转化为相应的同步测试序列；另外此生成模型还可以用来选择为测试系统增加外部同步通道的方法。
