At the present, almost all the industrial control systems utilize these three control systems. Among them each system has its own performance advantage and also has own defectiveness. In the developing process every system complements and promotes each other for the structure and performance. All of them are developing in the direction of more reliability, opener and easier to maintenance.

目前全球范围内的工业控制自动化系统几乎都是采用了这三类控制系统，它们在性能上各有所长，也有各自的局限性，各类系统在发展的过程中在结构和性能上相互补充、相互促进，都在向更可靠、更开放、可维护性更好的方向发展。
