板宽板厚多变量系统的自抗扰控制

针对精轧板宽板厚多变量系统具有强耦合、不确定性、大时滞、干扰因素多、非线性等特点，应用ADRC静态解耦和ESO动态解耦技术，给出了一种全新的多变量ADRC设计及实现方案。解耦后各通道的ADRC可分别按常规的单变量时滞系统来设计。为满足快速性要求，各通道的ADRC改由ESO、NF两部分组成，而且这两部分没有采用常规的非线性函数，而是改用线性函数。改进后的ADRC由Simulink编程实现。仿真结果表明这种方法的有效性。

Active Disturbance Rejection Control for Strip Width and Gauge Multi-System

This paper proposes a new Active Disturbance Rejection Control(ADRC) method for finishing Automatic Width Control and Automatic Gauge Control MIMO system.According to the serious decoupling,uncertainty,long time-delay,many disturbances and nonlinear etc of the plant,the MIMO ADRC based on static decoupling and ESO dynamic decoupling is proposed in order to eliminate the coupling between the loops,then each loop can be proposed by normal SISO ADRC delay system.The proposed ADRC of each loop only consists of the ESO and NF using linear function instead of normal non-linear function in order to meet the requirement of rapidity.Simulations on Simulink show good effectiveness of the control system.
