Intrac 程序包是瑞典隆德大学的控制系统 CAD 程序包的核心部分,是计算机终端用户与控制系统应用程序之间的软件接口,它实现人机对话的功能,将人的经验,知识、直觉、决策能力与计算机的高速运算能力、数据处理能力结合在一起,为控制工程技术人员设计控制系统提供了更高的灵活性与有效性。本文将对 Intrac 作简要介绍。 Intrac package is the core part of the control system CAD package of Lund University in Sweden. It is the software interface between the computer terminal user and the control system application program. It realizes the function of man-machine dialogue and integrates human experience, knowledge, intuition, Decision-making ability and the computer’s high-speed computing power, data processing capabilities combined to control engineering and technical personnel to design a control system provides a higher flexibility and effectiveness. This article will introduce Intrac briefly.
