一、概述随着计算机应用的逐步深入和工业水平的提高,工业控制对象也变得大型化和复杂化。工业控制规模已从局部控制发展到整个生产过程的控制、优化和调度,以及整个企业的控制和管理一体化。与此同时,控制理论也从古典控制理论发展到现代控制理论和智能控制理论。由于工业控制对象和控制理论的发展,这对计算机控制系统提出了新的要求,它必需满足: (1)人机联系好,便于集中操作,监视和管理大型现代化工业生产装置。 (2)在高度安全可靠的前提下,按预定的工艺指标控制复杂的生产过程。除完成一般单参数、单回路的控制外,还应易于实现非线
First, an overview With the gradual deepening of computer applications and industrial upgrading, industrial control object has become large and complex. The scale of industrial control has evolved from partial control to control, optimization and dispatch of the entire production process, as well as the integration of control and management throughout the enterprise. At the same time, control theory has also developed from classical control theory to modern control theory and intelligent control theory. Due to the development of industrial control object and control theory, it poses new requirements to the computer control system. It must meet the following requirements: (1) good man-machine connection, easy operation, monitoring and management of large-scale modern industrial production equipment. (2) Under the premise of highly safe and reliable, control the complicated production process according to the predetermined technological index. In addition to the general single-parameter control, single-loop control, but also easy to achieve non-linear
