Abstract

In this paper, the authors propose a novel design approach for the PID controller in the automatic voltage regulator (AVR) system using the Naked Mole Rat Algorithm (NMRA). The proposed algorithm has been extensively tested through MATLAB simulation studies. These studies have confirmed the effectiveness of the NMRA tuning method in achieving improved AVR system performance compared to the other tuning methods in the literature. In addition to performance evaluation, this article also investigates the robustness of the AVR system with an NMRA-tuned PID controller. This was achieved by conducting a disk-based stability analysis under model uncertainty. Also, the proposed NMRA-PID controller has a higher gain change tolerance than the TSA-PID controller for the given perturbations in the feedback loop of the AVR system for the specified values of disk size and skew. By studying the performance and robustness of the AVR system with an NMRA-tuned PID controller and comparing it with other techniques, this study provides insights into the benefits and capabilities of the proposed approach.
使用基于磁盘的稳定性分析方法对自动电压调节器进行鲁棒性和稳定性分析
在本文中,作者利用裸鼠算法 (NMRA) 为自动电压调节器 (AVR) 系统中的 PID 控制器提出了一种新的设计方法。所提出的算法已通过 MATLAB 仿真研究进行了广泛测试。这些研究证实,与文献中的其他调整方法相比,NMRA 调整方法在提高 AVR 系统性能方面非常有效。除性能评估外,本文还研究了采用 NMRA 调谐 PID 控制器的 AVR 系统的鲁棒性。这是通过在模型不确定性下进行基于磁盘的稳定性分析实现的。此外,在指定的磁盘大小和偏斜值下,对于 AVR 系统反馈回路中的给定扰动,所提议的 NMRA-PID 控制器比 TSA-PID 控制器具有更高的增益变化容限。通过研究使用 NMRA 调谐 PID 控制器的 AVR 系统的性能和鲁棒性,并将其与其他技术进行比较,本研究深入探讨了所提方法的优势和能力。
