摘要
本文从控制系统的可控性观点研究过程控制对控制器的基本技术需求。定义了控制器的控制周期概念;分析了模拟调节器与数字控制器的不同;举例讨论了受控过程对控制周期的量化需求;证明了控制周期是一个不可控环节;指出了快速性是对于数字控制器的一项基本技术要求。
The paper studies the technical requirements for controller from a viewpoint of controllability. It gives the definition of controlling cycle, analyses the differences between analogous regulator and digital controller, discusses the quantization requirement for controlling cycle in the controlled process by taking instances, proves controlling cycle is a uncontrollability, and points out quick-ability of controller is a basic technology requirement.
