TE过程是基于实际工业过程的过程控制案例，它是由美国伊斯曼化学公司的过程控制小组创建的，其目的是为评价过程控制和监控方法提供一个现实的工业过程。测试过程是基于一个真实工业过程的仿真，很适合于研究过程控制技术。其中的成分、动力学、运行条件等因为专利权的问题都作了修改。-TE process is based on the actual process of industrial process control case, it is by the process of U.S. Eastman Chemical Company control group created, and its object is to provide a realistic industrial process for the　uation of process control and monitoring method. Test procedure is based on a real industrial process simulation, well suited to study the process control technology. One of the components, dynamics, operating conditions and other problems have since been revised patent.
