集散系统中高精度控制器在现场实现的研究

HIGH-QUALITY CONTROL METHOD USED IN LOCALE PROCESSOR OF TOTAL DISTRIBUTED CONTROL SYSTEM

讨论了集散系统 ,尤其是监控与数据采集 (SCADA)系统中高精度设备的控制问题。在考虑工业设备自身固有特点的前提下 ,提出一种控制策略 ,它算法简单 ,完全适用于现场控制器 (低端处理器 ) ,并可由处理器的容量决定其控制精度。该方法还具有较强的鲁棒性 ,是对SCADA系统在动态控制方面的一个很好的补充。

The high quality control problem of total distributed system, especially of SCADA system is discussed. By taking into account the inherence of those manufacture equipment, a kind of control algorithm is put forward, because the algorithm is characterized by simpleness and being realized easily, it is very adapt to be applied on locale processor, and the control precision correspond with the capability of processor, the algorithm is also robust So it is good reinforce in dynamic process control of SCADA system
