To achieve robust stabilization and performance, several procedures are proposed whereby the desired sliding hypersurface is designed using Algebraic Riccati Equations (AREs) to bound disturbance effects in the sliding regime. These procedures for designing the sliding hypersurface can also be used in conjunction with any other Variable Structure Control (VSC) scheme that assures the reaching of a sliding mode.","PeriodicalId":297258,"journal":{"name":"1992 American Control Conference","volume":"91 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133876202","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 sensors could be active (3D or 2D radars) or passive (EO sensors measuring the azimuth and elevation angles of the source). The source of a detection can be either a real target, in which case the measurement is the true observation variable of the target plus measurement noise, or a spurious one, i.e., a false alarm. In addition, the sensors may have nonunity detection probabilities. The problem is to associate the measurements from the sensors to identify the \"real\" targets, and to obtain their position estimates. Mathematically, this (static) measurement-target association problem leads to a generalized three-dimensional (3-D) matching problem, which is known to be NP-hard. In this paper, we present a fast, but near-optimal 3-D matching algorithm suited for estimating the positions of a large number of targets (≫50) in a dense cluster for real-time applications. Performance results on several representative test cases solved by the algorithm are presented.","PeriodicalId":297258,"journal":{"name":"1992 American Control Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131498341","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 closed form of the description of system errors due to quantization is derived for the general class of linear digital control systems. We consider almost all kinds of quantization errors which may occur in general digital control systems; truncation or roundoff quantization errors of A/D and D/A conversions, and truncation or roundoff errors in arithmetic operations. We also develop a method to estimate the influence of the order of the arithmetic steps of control algorithms implemented in digital controllers on quantization errors. A mathematical description of the order of arithmetic steps in digital controller is introduced. The validity of the proposed analysis is comfirmed through numerical experiments.","PeriodicalId":297258,"journal":{"name":"1992 American Control Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130767407","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 proposed estimation and control law for delay compensation is formulated on the concept of the Linear Quadratic Gaussian (LQG), hereafter called Extended Linear Quadratic Gaussian (ELQG). Although the certainty equivalence property of LQG does not hold for ELQG in general, the combined state estimation and state feedback approach of ELQG offers a suboptimal solution to control of randomly delayed processes. Specifically, ELQG is applicable to analysis and synthesis of Integrated Communication and Control Systems (ICCS) for vehicle management of future generation aircraft and autonomous vehicles where a computer network is employed for distributed processing and on-line information exchange between diverse control and decision-making functions. Results of simulation experiments are presented to demonstrate the efficacy of the ELQG algorithm for flight control of an advanced aircraft.","PeriodicalId":297258,"journal":{"name":"1992 American Control Conference","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130772930","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}
