摘要

首先建立全局非线性集热管道机理模型在典型工况点处的相对阶次传递函数模型集;其次基于该模型集整定的线性自抗扰控制器参数训练高斯过程回归模型,以此预测不同出口温度设定值下的控制器参数;然后基于Kharitonov定理给出该变参数策略下闭环控制系统的稳定性分析;最后,仿真结果表明,当槽式太阳能集热场出口温度系统处于复杂运行条件时,所提出的变参数自抗扰控制策略具有良好的设定值跟踪性能、扰动抑制能力以及鲁棒性,与传统比例积分控制（PI）、自抗扰控制（ADRC）以及变参数PI控制器相比,同样具有更佳的单项性能和积分性能的指标表现。

Abstract

The temperature of the heat transfer oil plays a critical role in ensuring the safety and economic performance of parabolic trough solar thermal systems. However, due to the system’s inherent characteristics—such as large inertia, strong nonlinearity, and susceptibility to various disturbances—enhancing the performance of the outlet temperature control system in the collector field has emerged as a significant challenge and an important research focus. To address this issue, a comprehensive global nonlinear mechanistic model of the heat collection pipeline is first developed, along with a relative-degree transfer function model at typical operating points. Using these models as a foundation, the parameters of a linear active disturbance rejection controller （ADRC） are tuned and subsequently employed to train a Gaussian process regression model for predicting controller parameters at different outlet temperature setpoints. The stability of the closed-loop control system under this parameter-varying strategy is then analyzed using Kharitonov's theorem. Simulation results demonstrate that, under complex operating conditions, the proposed parameter-varying ADRC strategy achieves outstanding setpoint tracking, disturbance rejection, and robustness. Compared to traditional PI, ADRC, and parameter-varying PI controllers, the proposed approach delivers superior performance in both individual metrics and integral performance indices.
