摘 要
本研究针对动态负载环境下自适应控制系统的性能评估问题展开深入探讨。随着工业自动化程度的不断提高,控制系统面临日益复杂的工况变化,传统固定参数控制策略已难以满足实际需求。为此,本文提出了一种基于模型参考自适应控制的改进算法,通过引入在线参数估计和增益调度机制,有效提升了系统在动态负载条件下的鲁棒性和跟踪精度。研究采用理论分析与实验验证相结合的方法,首先建立了包含不确定性的系统数学模型,随后设计了具有自适应律的控制器结构。为验证所提方法的有效性,搭建了包含伺服电机和可变惯量负载的实验平台,在不同工况下进行了对比测试。

Abstract
In this study, the performance evaluation of adaptive control system in dynamic load environment is discussed. With the continuous improvement of industrial automation degree, the control system is faced with increasingly complex working conditions changes, and the traditional fixed parameter control strategy has been difficult to meet the actual demand. To this end, this paper proposes an improved algorithm based on model reference adaptive control, which effectively improves the robustness and tracking accuracy of the system under dynamic load conditions by introducing online parameter estimation and gain scheduling mechanism. Combining theoretical analysis and experimental verification, we first built the system mathematical model containing uncertainty, and then designed the controller structure with adaptive law. In order to verify the effectiveness of the proposed method, an experimental platform including servo motor and variable inertia load is built and tested under different working conditions.
