A modified single-vector based FCS-MPC with delayed and suboptimal switching for VSI
Conventional single-vector finite control set model predictive control (FCS-MPC) implements one switching state throughout the control period, resulting in significant harmonic distortion and variable switching frequency.

| description | Conventional single-vector finite control set model predictive control (FCS-MPC) implements one switching state throughout the control period, resulting in significant harmonic distortion and variable switching frequency. In this study, a modified single-vector FCS-MPC based on delayed and suboptimal switching is introduced for voltage source inverter (VSI). The proposed method can achieve a better voltage control performance while maintaining limited computational complexity and switching actions. Instead of switching directly to the optimal state at the start of the control period, the proposed method employs a delayed switching strategy to suppress total harmonic distortion (THD), which actually combines the previous state and the optimal state in one control period without additional switching action. Besides, when the optimal vector matches with the previous one, there is no switching action in conventional FCS-MPC. The proposed control instead introduces an additional suboptimal switching action after a delay, further reducing the THD. Moreover, the delay time is calculated using simplified procedures without extra predictions, resulting in a compact and easily implementable controller. The validity of the proposed approach is verified through hardware-based experimental results.© 2017 Elsevier Inc. All rights reserved. |
