Traffic flow theory and traffic flow model play an important role in testing and developing efficient motorway traffic control strategies, while macroscopic models of the Lighthill-Whitham-Richards (LWR) type fail to reproduce the capacity drop. This paper proposes a modified Cell Transmission Model(CTM) based on the special contribution of on-ramp flow on the capacity drop to reflect the capacity drop at merge in the first-order traffic flow model. We calibrate and validate the presented model with real traffic data, the validation results show that this model is robust and capable to capture capacity drop phenomenon.","PeriodicalId":262938,"journal":{"name":"2018 10th International Conference on Modelling, Identification and Control (ICMIC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122623732","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}

First, the mathematical model of the system is established, subsequently, the measurements are estimated by the unscented Kalman filter. Moreover, the residual errors between the estimated values and measured values are obtained. According to the residual errors, the fault of the system will be diagnosed.

Solid particle erosion leads to the damage of the steam turbine blade and the degradation of the turbine's performance. Taking a 660MW supercritical steam turbine, the numerical simulation is carried out aiming to get the impact density of SPE to the blades of the turbine's governing stage as its load varying respectively correspond to sliding pressure and constant pressure running modes. The influence of SPE with different valve control schemes are compared while the pressure keeping constant. The solid particle erosion of the steam turbine governing stage mainly occurs in the blades. As the load decreases during the sliding pressure operation, the erosion of the solid particles in the governing stage gradually increases. At high load, the valve control scheme has less effect on solid particle erosion and low load larger. Based on the analysis of the simulation results, a series of valve control scheme to reduce the SPE of governing stage are presented.","PeriodicalId":262938,"journal":{"name":"2018 10th International Conference on Modelling, Identification and Control (ICMIC)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124614152","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, a method is presented of terminal sliding mode control for the valve-controlled systems which can make the tracking error converge to zero within finite time. Actually, the main feature of this method is the terminal function involved in the sliding surface. The nonlinear items are introduced through the terminal function to build a moving terminal sliding surface. Based on the Lyapunov stability theory, the terminal sliding mode controller is constructed, which can realize finite-time convergence of position error. And the proposed control strategy is simulated on basis of a valve-controlled system model whose command functions is sine and cosine functions. The results of simulation show that the terminal sliding mode control method is feasible and effective for valve-controlled systems.","PeriodicalId":262938,"journal":{"name":"2018 10th International Conference on Modelling, Identification and Control (ICMIC)","volume":"415 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124819190","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 new detection indexes based on SIMO NOFRFs were constructed with the concept of information entropy, the definition and estimation methods were given.
