摘要:

模型预测控制(MPC)已成为一种well-established的现代控制方法,用于具有输出LC滤波器的三相逆变器,其中需要高质量电压和低总谐波失真(THD)。尽管MPC是一种直观的控制器,易于理解和实现,但它有显著缺点,即需要大量的在线计算来解决优化问题。另一方面,在电力电子和驱动领域,基于人工神经网络的无模型方法的应用正在迅速增长。本文提出了一种新的双级逆变器控制方案,结合MPC和前馈ANN,旨在降低THD并提高系统在不同负载类型下的稳态和动态性能。首先,MPC在训练阶段用于生成用于训练所提出神经网络所需的数据。然后,一旦神经网络经过微调,就可以在不需要使用MPC的情况下在线用于电压跟踪目的。所提出的基于ANN的控制策略通过MATLAB/Simulink工具进行仿真验证,考虑了不同的负载条件。此外,评估了基于ANN的控制器在多种线性和非线性负载下的不同运行条件下性能,并与MPC的性能进行比较,证明了所提出基于ANN的控制策略在稳态和动态性能方面的优异表现。

英文摘要:

Model predictive control (MPC) has become one of the well-established modern control methods for three-phase inverters with an output LC filter, where a high-quality voltage with low total harmonic distortion (THD) is needed. Although it is an intuitive controller, easy to understand and implement, it has the significant disadvantage of requiring a large number of online calculations for solving the optimization problem. On the other hand, the application of model-free approaches such as those based on artificial neural networks approaches is currently growing rapidly in the area of power electronics and drives. This paper presents a new control scheme for a two-level converter based on combining MPC and feed-forward ANN, with the aim of getting lower THD and improving the steady and dynamic performance of the system for different types of loads. First, MPC is used, as an expert, in the training phase to generate data required for training the proposed neural network. Then, once the neural network is fine-tuned, it can be successfully used online for voltage tracking purpose, without the need of using MPC. The proposed ANN-based control strategy is validated through simulation, using MATLAB/Simulink tools, taking into account different loads conditions. Moreover, the performance of the ANN-based controller is evaluated, on several samples of linear and non-linear loads under various operating conditions, and compared to that of MPC, demonstrating the excellent steady-state and dynamic performance of the proposed ANN-based control strategy.
