多变量系统的奈奎斯特阵列设计法目前已被推进到应用阶段。本文阐述了建立在多变量奈氏稳定判据基础上的奈氏阵列法的基本原理和设计步骤,并以化工过程的精馏塔控制为例,具体地说明了上述方法的使用和效果。
The Nyquist array design method for multivariable systems has now been advanced to the application stage. In this paper, the basic principles and design steps of the Naa’s array method based on the multivariate Nepalese stability criterion are described. Taking the distillation column of chemical process as an example, the application and effect of the above method are described in detail.
