随着微型计算机在工业控制中的推广应用,直接数字控制(DDC)均逐步代替常规模拟控制系统。为了研究和评价控制系统设计的合理性,应用软件设计的可靠性以及输入、输出通道的工作性能等,必须采用数模混合仿真系统进行仿真考验。本文介绍一种在国内广泛应用的DMJ-3系列模拟计算机与TP-801单板机组成的混合仿真系统及其仿真方法。
With the popularization and application of microcomputers in industrial control, direct digital control (DDC) gradually replaced the conventional analog control system. In order to research and evaluate the rationality of control system design, the reliability of application software design and the performance of input and output channels, we must use the mixed simulation system of digital and analog to simulate. This paper introduces a hybrid simulation system and its simulation method which is composed of DMJ-3 series computer and TP-801 single-board computer widely used in China.
