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.)

说明：  充分利用估计误差的比例,积分,微分信号考虑一类线性系统的参数化观测器设计问题,在加快观测器收敛速度的同时避免较大的超调.从理论上分析此类观测器设计的可行性,并从实际应用角度给出一种简单可行的参数设计方法.仿真实验表明:该观测器不但易于实现而且能够获得较好的估计效果,从而有利于在实际工程中的应用.(In this paper, the proportional, integral and differential signals of the estimation errors are fully utilized to consider the design of the parameterized observer for a class of linear systems. The convergence speed of the observer is accelerated and the overshoot is avoided. The feasibility of the design of the observer is analyzed theoretically, A simple and feasible parameter design method is given from the point of view of practical application. Simulation results show that the observer is not only easy to implement, but also can obtain good estimation effect, which is conducive to the application in practical engineering)
