Accurate and reliable position and heading angle measurements are important foundations for the accurate path-following of unmanned rollers. Due to the poor operation environment of the roller, the positioning signal often drifts or jumps, which affects the reliable operation of the system. To achieve reliable fault diagnostic in the positioning system, in this paper, a novel solution that combines total disturbance observation and support vector machine (SVM) classification, is proposed. A multi-body kinematic model is established with steering wheel angle and vehicle speed as inputs, and with the longitude, latitude and heading angle as outputs. The discrepancy of model estimates from the measured value is treated as total disturbance, to be estimated by the extended state observer. Then the estimated total disturbance, together with the measured position and heading angle are input into the support vector machine for faults classification. Experimental results show that the fault diagnosis accuracy is 95%, the improvement in accuracy and computational time is 9% and 12% respectively, compared with the conventional solution that only based on SVM.","PeriodicalId":119721,"journal":{"name":"2020 4th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":"210 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123167781","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 NGPC is designed on the basis of the Taylor series expansion to approximate the predictive response in finite time domain. Since NGPC cannot thoroughly remove the deviation in the load torque variation and parametric uncertainties, an improved SMDO is exploited to estimate and compensate the deviation of controller. The developed controller can fulfill the performance of strong robustness and fast dynamic response with easy regulation characteristics. The simulation results manifest the effectiveness of the designed control strategy applied to the PMSHM drive.","PeriodicalId":119721,"journal":{"name":"2020 4th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115746392","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}

However, in the actual driving process, the performance of the vehicle may be markedly different from the performance in test cycle. In order to generate the driving cycle that can represent the actual driving process, this paper adopts the driving data of an express truck with specific driving routes to construct the typical driving cycle of a city by combining Markov chain with Monte Carlo random sampling. The random response is added in the construction process, and the variation parameter is used to simulate the sudden traffic situation. CCPV and CPV parameters are set to evaluate the generated driving cycle. Through Simulink simulation, the reliability of the generated driving cycle is verified and the influence of different statistical characteristics is determined.","PeriodicalId":119721,"journal":{"name":"2020 4th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125405775","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}

Therefore, this paper conducts an experimental study on the influence of slightly overcharging cycles on battery performance degradation, and builds a semi-empirical capacity degradation model under slightly overcharging cycles on this basis. The experimental results show that the slightly overcharging cycle causes the capacity decay of the battery to be significantly accelerated, and its capacity decay will also cause the capacity “diving” phenomenon at the end of its life under normal cycle conditions. The slightly overcharging cycle has little effect on the internal polarization resistance of the battery. But it has a greater impact on the ohmic internal resistance due to the thickening of the SEI film.","PeriodicalId":119721,"journal":{"name":"2020 4th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122431820","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}

It offers promising advantages over conventional power sources in backup power supplies, distributed generation and vehicle power. A rapid response to the actual power required by load is of great significance to improve the economy and efficiency of the system. However, due to various uncertainties such as frequent disturbances and inaccurate model, the net power control has certain challenges. Therefore, a data-driven nonlinear subspace identification method is developed to build the model of net power. A segmented and consecutive step response of net power for PEMFC system are identified and analyzed, the models are verified by high-fidelity simulation data. Data-driven active disturbance rejection control (ADRC) algorithm is developed to control the model. Internal and external disturbances are considered as a total term, which is estimated and compensated by real-time input-output data and ADRC, respectively. Compared with the integral absolute error of the conventional proportion integral and proportion integral derivative control, the performance of ADRC is improved by about 89.81 % and 78.92%, respectively. Therefore, the proposed ADRC can improve the dynamic performance of PEMFC system in terms of set-point tracking performance, disturbance rejection performance and robustness.","PeriodicalId":119721,"journal":{"name":"2020 4th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116730412","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}

Thus, this paper proposes a new framework in which Fully Homomorphic Encryption (FHE) and Blockchain technology are combined to compute encryption data on the cloud and record trails of cloud request. In this framework, private data can be protected, the scope of data usage will be limited, and at the same time, the execution of specific type of computations with encryption data on the cloud are fulfilled.
