Abstract

The primary goal of the Automatic Voltage Regulator (AVR) is to control the terminal voltage at the desired level. The controller used in AVR must be capable of maintaining generator terminal voltage in various operating conditions and also withstand uncertainty. In this paper, Feedback Error Learning (FEL) controller has been proposed to control the AVR system. FEL structure consists of the classical controller (PD controller) and the intelligent controller (MLP neural network controller). This control strategy has been employed to control unknown and uncertain plant model. Salp Swarm Algorithm (SSA) has been used to obtain the initial weights, biases and the number of neurons of the MLP neural network. The training methods used in this research are Stochastic Gradient Descend (SGD) and Root Mean Square propagation (RMSprop) that in particular; these methods are used in deep learning. The robustness and effectiveness of the proposed method has been studied in different operating conditions. The results demonstrate that the proposed strategy outperforms other methods.
基于RMSprop和Salp群算法的自动调压系统反馈误差学习控制器
自动电压调节器(AVR)的主要目标是将终端电压控制在所需的水平上。在AVR中使用的控制器必须能够在各种运行条件下保持发电机端子电压,并承受不确定性。本文提出了反馈误差学习(FEL)控制器来控制AVR系统。FEL结构由经典控制器(PD控制器)和智能控制器(MLP神经网络控制器)组成。该控制策略已被用于控制未知和不确定的对象模型。利用Salp群算法(Salp Swarm Algorithm, SSA)获得MLP神经网络的初始权值、偏置和神经元数。本研究中使用的训练方法主要是随机梯度下降(SGD)和均方根传播(RMSprop);这些方法用于深度学习。研究了该方法在不同工况下的鲁棒性和有效性。结果表明,该策略优于其他方法。
