摘要
为解决广义对象的多变量强相关和大时延的问题,采用多变量Smith预估器对时延的补偿,运用Rosenbrock’s Inverse Nyquist Array Method来设计用以削弱回路间相关作用的补偿器,应用单变量系统的校正设计方法最终完成主通道动态控制器的设计。文中还介绍了一个系统设计的实例和现场应用的情况。
In order to solve the strong interaction and long time-delay problem in generalized ob- ject,a multivariable Smith predictor is used to compensate the time-delay and,in the mean time, a compensator is designed for reducing the interaction between loops with Rosenbrock's Inverse Nyquist Array Method,and the dynamic controller of main loops is de- signed with modifying design method of single-variable system. An example of system design and actual application in an crude oil atmospheric distillation tower is also given.
