Abstract
The voltage tracking capability of conventional moving-discretized-control-set model-predictive-control (MDCS-MPC) in the dual-active-bridge (DAB) converter is affected by parameter mismatch and measurement noise. To address these issues and enhance voltage tracking capability, a continuous-control-set model-free predictive voltage control with noise-suppression (CCS-MFPVC-NS) method is proposed. The proposed method eliminates the parametric effect by establishing and updating an ultra-local model of DAB. Additionally, it reduces the impact of measurement noise on MFPVC by using an extended state observer, thereby enhancing the voltage tracking capability of the DAB converter. Experimental results validate the feasibility and performance of the proposed CCS-MFPVC-NS method. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
具有噪声抑制的DAB变换器的连续控制集无模型预测电压控制
传统的移动离散控制集模型预测控制（MDCS-MPC）在双有源电桥（DAB）变换器中的电压跟踪能力受到参数失配和测量噪声的影响。为了解决这些问题并增强电压跟踪能力，提出了一种带噪声抑制的连续控制集无模型预测电压控制（CCS-MFPVC-NS）方法。该方法通过建立和更新DAB超局部模型来消除参数效应。此外，采用扩展状态观测器降低了测量噪声对MFPVC的影响，从而增强了DAB变换器的电压跟踪能力。实验结果验证了CCS-MFPVC-NS方法的可行性和性能。©2025日本电气工程师协会和Wiley期刊有限责任公司。
