Due to the drastic load and speed changes during the underwater-aerial process, the magnetization state of VFMM also needs to be accordingly adjusted to permit high efficiency over a wide operational range. This will cause pronounced changes in the equivalent machine parameters, thereby affecting the robustness of the overall system. Thus, a ILESO-based MPCC method is proposed to extract the errors caused by the parameter variations in the system and compensate for the error in the driving prediction model. The ILESO parameters are easy to be tuned and implemented, while also addressing the robustness issue of the MPCC parameters. Finally, the simulation results are provided to validate the effectiveness of the proposed method, considering various operating conditions of UAVs in different environment.","PeriodicalId":231381,"journal":{"name":"2023 IEEE International Conference on Predictive Control of Electrical Drives and Power Electronics (PRECEDE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125448364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to traditional flat top pulse current sources, the proposed algorithm generates a controlled current overshoot in the magnet, increasing the magnetic field stabilization speed by approximately 50%.

The resulting zero-sequence current (ZSC) will cause additional torque ripple. To this end, the active control of ZSC should be taken into consideration. In this paper, an active ZSC suppression-based model predictive current control scheme for series-winding permanent magnet synchronous machines (SW-PMSMs) is proposed. First, based on the voltage vector (VV) distribution of three-phase SW-PMSM, six VVs without zero-sequence component are chosen as the basic VVs in $alpha-beta$ subspace. Next, the virtual VVs are employed to obtain the VVs only containing zero-sequence component, and they are utilized as the basic VVs in zero-sequence subspace modulation. Subsequently, the optimal VVs and their duty ratios in $alpha-beta$ and zero-sequence subspaces are selected and calculated separately to track the reference VVs according to the concept of deadbeat control. Next, the optimal VVs under the calculated duty ratios in different subspaces are combined and synthesized to generate switching sequences with constant switching frequency. The proposed scheme realizes the active ZSC suppression of SW-PMSM with current performance improvement. Meanwhile, time-consuming enumeration and cost function calculation can also be avoided. Finally, experimental results verify the proposed scheme and recognize the necessity of active ZSC suppression.","PeriodicalId":231381,"journal":{"name":"2023 IEEE International Conference on Predictive Control of Electrical Drives and Power Electronics (PRECEDE)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129019249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
