By designing a filter to generate a residual signal, a fault detection system for SbW system is constructed via delta operator and a threshold function is given. Based on the traditional robust fault detection filter and linear matrix inequality (LMI) approach, the system fault detection can be converted to the solution of the robust control problem. Then the solvability condition of the designed fault detection filter is achieved by solving a convex optimization problem. Finally, the performance of the proposed fault detection system is validated.","PeriodicalId":158442,"journal":{"name":"2018 37th Chinese Control Conference (CCC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125500375","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}

Ultrasonic echo tracking is a kind of new technology risen in recent years to detect arterial elasticity. Arterial elasticity coefficients are got by processing the ultrasound echo signal transmitted in different organs and tissue of human. In ultrasonic echo tracking, accurately estimate the time shift between two signals or phase shift is the key problem of elasticity estimation. Although the correlated technique can be used to realize, yet its calculation problem is the bottleneck of the implementation. In this paper, an improved Newton iterative algorithm was applied to estimate time shift of ultrasonic echo signal, so the precise time displacement estimation was achieved, and the problem of aliasing was overcome at the same time. In addition, because the ultrasonic echo data is large, and large part of it is unnecessary, so an adaptive testing blood vessel position tracking gate setting technology is proposed to improve the efficiency of data processing, and it reduced the computational complexity to a certain extent and improve the efficiency of data processing.","PeriodicalId":158442,"journal":{"name":"2018 37th Chinese Control Conference (CCC)","volume":"12 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":"115232257","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}

Fuzzy logic and neural network are integrated effectively to make the proposed model with better dynamic response. Reliable large amount of experimental data sets from existing testing platform are employed to train this model and verify through simulation with MATLAB environment. The results show that the proposed model agrees well dynamically with the LDAC systems. The average testing errors are less than 5% for humidity ratio prediction and less than 10% for temperature prediction, respectively.

The power waveforms are generated from the delay signals of Beidou MEO satellite. The remote sensing of GNSS concept is utilized to get information from sea surface. Because, this technique has been already proved as an effective tool to retrieve significant information from earth's surface since last twenty years. Still now, it has been utilizing as an advance technique for sea state monitoring, i.e. sea wind speed & direction, sea wave height, sea roughness measurement and so on. It is mainly generated the waveforms of Beidou MEO satellite for direct and reflected signals. It is obtained that the amplitude & shape of these power waveforms are varying according to wind speed. It is indicated that there is a sharp relationship between the amplitude of the waveforms and sea wind speeds. Two models are used to generate the waveforms from reflected signals. The wave spectrum model is used to find sea surface slopes i.e. up & cross variance and these up & cross variance is used as input on Z-V scattering model to generate power waveforms. The real wind speed of the experiment site of GNSS-R data collection for same time domain is also collected. The linear regression method is used to established a relationship between wind speeds and amplitudes of the waveforms. This relation is used to measure the sea wind speed. It is found that estimated wind speeds are matched closely with real wind speed and model waveforms performs good results with real data waveforms.","PeriodicalId":158442,"journal":{"name":"2018 37th Chinese Control Conference (CCC)","volume":"38 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":"115611736","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}

A new switching fault-tolerant controller is proposed based on the dwell time bounded by the minimal time length before total loss of effectiveness (TLOE) of an actuator group and the maximal time length spending for an actuator group recovering from TLOE mode. By estimating the infimum of the fault parameters for all active times, the fault for each actuator is allowed to appear infinite many times. The boundedness of the (adjustable) jump size of Lyapunov functions for different actuator groups at switching instants is guaranteed by exploiting the parameter projection operator. Under the designed controller and switching signal, the output tracking error of the system can be driven to a tunable neighborhood of the origin.
