参数自适应DAHLIN调节器

A PARAMETER ADAPTIVE DAHLIN REGULATOR

本文提出了一种新的数字控制算法,它是基于Dahlin数字控制算法和递推自适应策略,它能同时辨识和过程时滞,并具有自动整定调节器参数的功能。仿真结呆表明,它具有良好的鲁棒性,克服了由于模型失配时的DDahlin调节器性能的降低,该算法对于大时滞、慢时变的工业过程控制是可行的和有效的。

This Paper introduces a new approach,which is based on dahlin algorithm and recursive adaptive scheme and can estimate the processparameters and the time delay simultaneously and use design formulas for automatic tuning of the Dahlin regulator papamters. The simulations showthat this adaptive control algorithm has good robustness indeed and canimprove Dahlin regulator performance when models don't conform. The adaptivealgorithm is proved to be feasible and effective for use in many industrialprocesses with large time delays and slowly time varying.
