Embodiment

[0058] For a widely studied chemical hydrocarbon fractionator process

[0059] The first step is to design a slidable slider on the configuration interface, and set the initial value of the adjustable parameter of the controller to 1. The data such as object model identification parameters are sent to the storage unit RAM by the industrial computer; and the system is set to the "offline" adjustment state on the configuration interface. According to attached image 3 The closed-loop control structure diagram shown builds a closed-loop control system. The identification model of the chemical hydrocarbon fractionation tower process is as follows:

[0060] G ( s ) = 12.8 e - s ...

Abstract

A method for designing decouple controller analysis of multivariable time lag system includes carrying on identification of transfer function matrix for chemical industrial multivariable time lag procedure, designing two regulation factors being able to be realized by controller and designing decouple controller, leading designed controller to be infinite high order if GO ( s ) still contains time lag item after object transfer function matrix is decomposed, applying controller order-decreasing technique to carry out order-decreasing on controller.

Description

technical field [0001] The invention relates to a method in the technical field of industrial process control, in particular to an analytical design method for a decoupling controller of a multivariable time-delay system. Background technique [0002] Multi-input and multi-output processes with transmission delays are ubiquitous in chemical production, and with the rapid development of various advanced production processes, more and more production processes are constructed as high-dimensional multi-variable control systems, so as to realize Produce high-quality products efficiently. However, most of the developed univariate control methods are difficult to apply to multivariable processes due to the cross-linking coupling effect among the output channels of multivariable processes. At present, the research methods for multivariable systems mainly include linear quadratic optimization (LQG) design method, quantitative feedback method, Nyquist array method, sequential hyster...
