摘要

由于缺乏清晰的频域解释，工程师往往无法意识到主动抗扰控制（ADRC）的性能改进可能会损害稳定裕度。这项工作提出了一种面向相位余量（PM）的ADRC设计方法，用于车辆到电网（V2G）支持的直流微电网中的双有源桥（DAB）转换器。该方法在保证足够PM的同时提高了交叉频率。作为一种实用的通用设计方法，它可以很容易地推广到其他应用中。实验结果验证了其在不同功率流方向和DAB变换器调制模式下的有效性，并且与传统的经验ADRC设计相比，在延迟下的稳定性显着提高。

Practical phase-margin-oriented ADRC design method for dual active bridge converters in V2G-enabled DC microgrids

The absence of a clear frequency-domain interpretation often prevents engineers from realizing that performance improvements by active disturbance rejection control (ADRC) may compromise stability margins. This work presents a phase-margin (PM)-oriented ADRC design method for dual active bridge (DAB) converters in vehicle-to-grid (V2G)-enabled DC microgrids. The proposed method improves crossover frequency while ensuring a sufficient PM. As a practical and general design method, it can be readily extended to other applications. Experimental results verify its effectiveness under varying power flow directions and modulation modes of DAB converters, and demonstrate significantly enhanced stability under delays compared to conventional empirical ADRC designs.

期刊介绍： Control Engineering Practice strives to meet the needs of industrial practitioners and industrially related academics and researchers. It publishes papers which illustrate the direct application of control theory and its supporting tools in all possible areas of automation. As a result, the journal only contains papers which can be considered to have made significant contributions to the application of advanced control techniques. It is normally expected that practical results should be included, but where simulation only studies are available, it is necessary to demonstrate that the simulation model is representative of a genuine application. Strictly theoretical papers will find a more appropriate home in Control Engineering Practice''s sister publication, Automatica. It is also expected that papers are innovative with respect to the state of the art and are sufficiently detailed for a reader to be able to duplicate the main results of the paper (supplementary material, including datasets, tables, code and any relevant interactive material can be made available and downloaded from the website). The benefits of the presented methods must be made very clear and the new techniques must be compared and contrasted with results obtained using existing methods. Moreover, a thorough analysis of failures that may happen in the design process and implementation can also be part of the paper. The scope of Control Engineering Practice matches the activities of IFAC. Papers demonstrating the contribution of automation and control in improving the performance, quality, productivity, sustainability, resource and energy efficiency, and the manageability of systems and processes for the benefit of mankind and are relevant to industrial practitioners are most welcome.
