This paper mainly discusses the function, design principle, realizing method and local address assignment in the GPIB-VXI controller module. It also introduces how to control the data flow of module and how to realize it in hardware. 本文主要介绍了GPIB&VXI控制器模块的功能、设计原理、实现方法及本地总线的地址分配,并着重介绍了模块的数据流控制方式,以及在硬件上如何实现。
The mechanism of local bus arbitration is different from CPU and interface chip in the GPIB-VXI controller module. 在GPIB-VX1控制S模块中,CPU和接口芯片的本地总线仲裁机制不同,文中分别对其加以讨论,提出了一种实现各仲裁线之间的转换、切实可行的实际电路。
The noise ' covariance and information distribution coefficient of local filtering were modified online by the fuzzy logic adaptive controller in order to module Kalman filtering to be optimal and to improve the positioning accuracy of the integrated navigation system. 采用模糊逻辑自适应控制器对联合卡尔曼滤波器的噪声方差和信息分配系数进行在线自适应调整,避免了子滤波器的发散,保持了全局估计的高精度。
