摘要
本文针对应用PLC做闭环控制时对信号的处理过程进行了深入分析研究,提出了该类控制系统近似看作闭环数字控制系统在建模分析时理论与实际情况更接近的思想,为相关技术人员提供了一定的理论根据。
Process of dealing with signal of PLC is intensively analyzed when PLC is applied to closedloop control system in this paper, which provides an idea that this kind of control system may be looked on as closed-loop digital control system during establishing math module, and provides theory foundation for related technician.
