The filter uses a classic fourth-order cross-coupled structure. The negative coupling is realized by a TE $_{mathbf{102}}$ mode. To provide convenience for connection and measurement, two vertical transitions with the same height as the filter are designed on the upper and lower sides. The simulation results show that the filter has a center frequency of 341.2 GHz with a 3 dB FBW of 19.7 GHz. The average insertion loss (IL) of the passband is 0.7 dB, and the return loss is better than 15 dB. The influences of machining tolerance caused by the MEMS process on center frequency, bandwidth, and stopband rejection are also analyzed in this paper.","PeriodicalId":316980,"journal":{"name":"2021 IEEE 4th International Conference on Electronics Technology (ICET)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128415673","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}

Firstly, a nonlinear dynamic model of the WS-UAV is established based on the Lagrange method. Secondly, according to the motion characteristics of the multi-body mechanism of the WS-UAV, a cascade controller consists of the position loop PD controller and the attitude loop sliding mode controller is constructed, in order to suppress the swing of the water sampler, estimated acceleration of the water sampler is fed back. Finally, the impact caused by the wind and the water flow is considered in the simulation.

The antenna operates in the first zero-mode generated by shorting pins, hence, to achieve a miniaturized size with 0.15 $lambda_{0} times 0.21 lambda_{0}$ ($lambda_{0}$ is the free-space wavelength of 28 GHz). However, the multi-layer configurations induce interferences to the mmWave antenna, particularly generates high-mode resonances. The proposed SICL design containing eight via holes resembles the transmission line structures in the substrate, thus, mitigate these interferences and maintain the S11 parameter the same as that of original two-layer design. Moreover, using the miniaturized microstrip patch as antenna element, a $4 times 1$ array is also constructed and discussed.

However, due to the strong nonlinearity of the system and the fixed droop coefficient, the system has poor stability under transient conditions, which is prone to full load. In order to improve the response speed and stability of the system, an adaptive integrated coordinated control strategy based on sliding mode theory is proposed. The strategy adopts a double closed loop cascade control structure, the outer-loop controller performs adaptive droop control based on the comparison of the MMC real-time power margin with the power reference command, and the inner-loop controller is designed based on a sliding film variable structure with current error as the sliding film plane. The simulation model of MMCMTDC direct current transmission system was built in PSCAD/EMTDC. The simulation results of the proposed control strategy show that the control strategy can effectively avoid the full load margin of the system when the MMC is small, and the strategy also can improve the adaptability and dynamic performance of the system compared with the traditional control strategy.","PeriodicalId":316980,"journal":{"name":"2021 IEEE 4th International Conference on Electronics Technology (ICET)","volume":"216 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133172628","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}

The operation mechanism of proposed structure has been investigated and the effects of related parameters have been discussed.
