Abstract

This article presents a study on controlling a class of large-scale systems composed of interconnected subsystems. The systems are represented by discrete block-oriented models with unknown parameters. This article proposes a novel adaptive sliding mode control strategy to address the tracking control problem and minimize the impact of interconnection. This approach leverages the robustness of sliding mode control against unmodeled dynamics and disturbances with the advantages of adaptive control. To adapt the system’s parameters, a recursive parametric estimation algorithm using least-squares techniques is employed. The proposed method offers benefits such as robustness against parameter uncertainties, handling of nonlinearities, improved tracking accuracy, and reduced chattering phenomena. The effectiveness of the method is demonstrated through the evaluation of two simulation examples.

互联非线性系统的分散离散自适应滑模控制

本文研究了一类由互联子系统组成的大型系统的控制问题。该系统采用离散的、面向块的、参数未知的模型来表示。本文提出了一种新的自适应滑模控制策略来解决跟踪控制问题，并将互连的影响降到最低。该方法利用了滑模控制对未建模动态和扰动的鲁棒性和自适应控制的优点。为了适应系统的参数，采用了最小二乘递归参数估计算法。该方法具有抗参数不确定性、处理非线性、提高跟踪精度和减少抖振现象等优点。通过两个仿真算例验证了该方法的有效性。

期刊介绍： Systems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering refleSystems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering reflects this diversity by giving prominence to experimental application and industrial studies. "It is clear from the feedback we receive that the Journal is now recognised as one of the leaders in its field. We are particularly interested in highlighting experimental applications and industrial studies, but also new theoretical developments which are likely to provide the foundation for future applications. In 2009, we launched a new Series of "Forward Look" papers written by leading researchers and practitioners. These short articles are intended to be provocative and help to set the agenda for future developments. We continue to strive for fast decision times and minimum delays in the production processes."
