Abstract

Multi-phase machines are being proposed in research and industry applications due to their inherent advantages. Finite Control Set Model Predictive Controllers (FCS MPC) constitute a flexible tool to deal with the increased number of phases. However, FCS MPC is computationally demanding, reducing its applicability with fast power converters. Region-based methods for FCS MPC have been recently proposed to reduce the control computation time. However, these methods are still hindered by the use of a fixed application time for the selected voltage. The paper presents a region-based method that uses variable application times. The method achieves fast computation of the voltage vector and its application time. Moreover, the application time can be found with fine resolution unlike previous approaches and without iterations. The proposal is experimentally validated using a laboratory test bench based on a symmetric five-phase induction machine showing improved control results and a reduction in harmonic content.

基于区域的可变采样周期多相预测控制器

多相机器因其固有的优势而被广泛应用于研究和工业领域。有限控制集模型预测控制器（FCS MPC）是应对相数增加的灵活工具。然而，FCS MPC 对计算要求较高，降低了其在快速功率转换器中的适用性。最近有人提出了基于区域的 FCS MPC 方法，以减少控制计算时间。然而，这些方法仍然受到所选电压使用固定应用时间的限制。本文提出了一种使用可变应用时间的基于区域的方法。该方法可以快速计算电压矢量及其应用时间。此外，与之前的方法不同，该方法无需迭代，就能找到精确的应用时间。通过使用基于对称五相感应机的实验室测试台对该提案进行实验验证，结果表明控制效果得到改善，谐波含量也有所降低。

期刊介绍： Control Engineering Practice strives to meet the needs of industrial practitioners and industrially related academics and researchers. It publishes papers which illustrate the direct application of control theory and its supporting tools in all possible areas of automation. As a result, the journal only contains papers which can be considered to have made significant contributions to the application of advanced control techniques. It is normally expected that practical results should be included, but where simulation only studies are available, it is necessary to demonstrate that the simulation model is representative of a genuine application. Strictly theoretical papers will find a more appropriate home in Control Engineering Practice''s sister publication, Automatica. It is also expected that papers are innovative with respect to the state of the art and are sufficiently detailed for a reader to be able to duplicate the main results of the paper (supplementary material, including datasets, tables, code and any relevant interactive material can be made available and downloaded from the website). The benefits of the presented methods must be made very clear and the new techniques must be compared and contrasted with results obtained using existing methods. Moreover, a thorough analysis of failures that may happen in the design process and implementation can also be part of the paper. The scope of Control Engineering Practice matches the activities of IFAC. Papers demonstrating the contribution of automation and control in improving the performance, quality, productivity, sustainability, resource and energy efficiency, and the manageability of systems and processes for the benefit of mankind and are relevant to industrial practitioners are most welcome.
