建立能真正描述生产过程特性的数学模型,合理的选择计算机系统的硬件结构和设计完备正确的软件系统结构是应用工业控制机对生产过程进行自动控制的三个重要组成部分。前几讲已对计算机系统硬件结构、数学模型和控制原理作了介绍。但不管你采用的控制方案是多么先进,计算机系统硬件是怎样完整,如果设有软件,它们还是死的东西,最终还必须靠软件来组织和发挥各个任
The establishment of a mathematical model that can truly describe the characteristics of the production process, a reasonable choice of the hardware structure of the computer system and the design of a complete and correct software system structure are three important components of the automatic control of the production process by the industrial control machine. The last few talks have introduced the computer system hardware structure, mathematical model and control principle. But no matter how sophisticated the control scheme you are using, how complete are the hardware of the computer system, and if they are software they are still dead and eventually have to be organized and empowered by software
