【摘要】 介绍基于ORCAD/PSpice的线性测控系统计算机辅助分析方法。ORCAD/PSpice较目前常用的MATLAB有其独特之处,较好地解决控制模型电路分析中命令与函数难以掌握的问题,特别为解决多输入多输出的系统分析难点提供了有效途径。文中分别从系统方框图绘制,稳态误差分析和波特图绘制三部分入手,详细讨论利用ABM库实现和操作的技术,这种直观的辅助分析方式可以增强对测控系统感性认识,且易于定量分析。更多还原

【Abstract】 This article introduced ORCAD/PSpice based analysis of linear measurement and control system. Pspice has some specific features compared with MATLAB. For example, Pspice doesn’t require students to grasp command and function in control circuit analysis, and especially provides an effective way to resolve system analysis problem in the case of multi-port input and output. The article obtained separately from three parts: the system block diagram plan, the static error analysis and the baud chart draws up. The techniques to use ABM database were discussed in detail. This direct-viewing assistance analysis way might enhance the knowledge of the measurement and control system. It also makes the quantitative analysis easier.更多还原
