摘要
在研究不平衡智能治理装置控制技术的基础上,分析了时滞对治理装置的影响,并结合自适应神经网络的特点,提出了基于非线性自回归神经网络(NARX)神经网络的三相负荷不平衡智能治理装置控制方案。分析比较了改进NARX控制与常规NARX控制下换相开关三相不平衡智能治理装置的性能,通过仿真和实验验证了改进NARX控制方案的可行性与优越性。
This paper studies the phase-change switch for three-phase unbalanced load and the influence of time delay on the phase-change switch automatic regulating device.Considering with the characteristics of Nonlinear Auto-regressive with External Inputs(NARX)neural network,this paper proposed a control method with improved NARX neural network for the phase-change switch system so as to improve the regulating precision or decrease the action times of the switches.This paper analyzes and compares the performance of the three-phase imbalance intelligent control device under the improved NARX control and the conventional NARX control,and verifies the feasibility and superiority of the improved NARX control scheme through simulation and experiment.
