Automatic Regulation Time Series for Industry Processes

Abstract EN

A nonlinear digital control scheme is proposed for analyses and designs of stable industry processes.

It is derived from the converging characteristic of a specified numerical time series.

The ratios of neighbourhoods of the series are formulated as a function of the output of the plant and the reference input command and will be converted to be unities after the output has tracked the reference input command.

Lead compensations are also found by another numerical time series to speed up the system responses on the online adjusting manner.

A servosystem, a time-delay system, a high-order system, a very-high-order system, and a 2 × 2 multivariable aircraft gas turbine engine are used to illustrate effectiveness of the proposed nonlinear digital controller.

Comparisons with other conventional methods are also made.
