Abstract In this paper, a novel design method for the determination of the optimal values of the Proportional – Integral – Derivative (PID) controller parameters of an Automatic Voltage Regulation (AVR) system is proposed. This method is based on the usage of the Equilibrium Optimizer (EO) algorithm. In order to demonstrate the applicability and efficiency of the proposed algorithm, the literature review of papers dealing with AVR PID design has been considered first. After that, time responses of the AVR system (including PID controller optimized by EO algorithm) with and without different kinds of disturbances have been compared with corresponding results determined for different literature approaches. Furthermore, the comparisons in terms of the accuracy, requested time for one iteration, the total execution time of the algorithm, and convergence characteristics are performed, too. The results show that the EO algorithm significantly outperforms other techniques for all considered criteria.

基于平衡优化算法的自动电压调节系统控制器设计与鲁棒性分析

摘要 在本文中，提出了一种用于确定自动电压调节 (AVR) 系统的比例 - 积分 - 微分 (PID) 控制器参数最优值的新设计方法。此方法基于均衡优化器 (EO) 算法的使用。为了证明所提出算法的适用性和效率，首先考虑了处理 AVR PID 设计的论文的文献综述。之后，将 AVR 系统（包括通过 EO 算法优化的 PID 控制器）在不同类型扰动下的时间响应与不同文献方法确定的相应结果进行了比较。此外，在准确性方面的比较，一次迭代的请求时间，算法的总执行时间，和收敛特性，也是。结果表明，EO 算法在所有考虑的标准上都明显优于其他技术。
