10.3.- 工业应用和系统

在流程工业中,设备和装置的优化运行是至关重要的。为了达到这个目的,安装了传感器,用于测量需要调节的参数(受控变量),执行器,允许修改其值(受控变量),控制器,定义执行值。这套设备称为控制系统。

一些最常见的例子在工业上是流量控制系统,通过气动阀或电磁阀的流体的水平或温度,控制系统的pH值的解决方案,通过计量泵或控制系统的压力和流量的气体。然而,在大型工业工厂中,这些简单的控制回路并不是孤立发生的,而是作为由分布式控制系统或DCS控制的更复杂过程的一部分。在这些系统中,简单的控制回路由工业控制器和/或可编程逻辑控制器(PLC)进行本地调节,并由中央监督控制和数据采集系统(SCADA)进行监控。

这种自动化带来的生产力和效率的提高,有利于在传统PID控制的基础上实现更复杂的控制算法,如级联控制、前馈控制、选择控制等。此外,其他类型的算法也在研究中,如预测控制、自适应控制或模糊控制。这些系统的另一个重要趋势与工业通信领域有关,包括用基于Profibus、Modbus或以太网等协议和标准的多点数字网络取代传统4-20mA电流回路的点对点连接。
