摘　　要：介绍一种由8098单片机系统构成的智能仿真器.该仿真器具有八路放大系统及时间常数可调的一阶惯性环节和四路基于A/D-存储-D/A原理的延迟环节.各环节组合可以构成八阶以下带大纯滞后的模拟被控对象,可以模拟温度、压力、流量和物位等各种过程参数.An intelligent process simulator constructed with 8098 single chip computer system is introduced. This simulator composed of eight first order inertial elements with adjustable multiplication factor and time constant and four delay elements based on A/D-Storage-D/A principle. By composing these elements, up to the 8th order controlled objects with large deadtime can be constructed for simulating various process parameters such as temperature, pressure, flow and material level.
