This is done by formulating the problem as passing the image through a bandpass filter of bandwidth Delta corresponding to the data sample size and evaluating the magnitude of the resulting image. It is revealed that the reconstruction is essentially equivalent to the magnitude of the resulting image obtained by passing the original magnitude function through a set of two dimensional extended all-pass filters. The concept of an extended all-pass filter is introduced to describe a filter whose amplitude response spreads over the whole frequency space with random variations. It is shown that the quality of the reconstruction is content-dependent and improves with increase of the sample size.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128003912","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 problem of planning minimum-time paths for robot manipulators becomes complicated when two manipulators are traveling in the same workspace, especially in intersecting paths. This problem is solved using a variational technique called the method of local variations (MLV), which allows constraints to be placed on both state and phase variables. To solve the problem, a collision-free path and a parameter are chosen for each manipulator. Each of these paths is then parameterized with respect to the parameter chosen for the manipulator. Geometric collision checking is then used with the MLV to ensure that the manipulator traveling at its maximum possible speed does not collide with the other. The proposed algorithm is tested through digital simulations.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121211465","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}

Because the DBF has an annular structure, a number of advantages accrue to the algorithm: (1) complete azimuthal data are efficiently observed, without window operations; (2) a much narrower beam that is 1/3 of the well-known limit of (wavelength)/(aperture size) can be obtained by implementation of an exact inverse solution; (3) an annular systolic array processor can be realized owing to the isoazimuthal feature of the beam forming algorithm. The concept and performance of the proposed DBF system are demonstrated theoretically. It is also shown experimentally that this DBF system can form 256 beams at one time, and a total of 65536 points are detected within 300 ms.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125456972","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}

Force controls are important for walking robots because each leg must be allotted proper equal force (weight). The proposed control architecture consists of a position servo system with quick response, a torque observer, and a surface characteristics estimator. The control has two phases: a command is given to the position servo system to let the leg move to the specified position and the torque observer detects the contact force. A predictor algorithm estimates the relation between the position and the force by using a database constructed experimentally, and a new position command is generated on the basis of this relation. The total system acts like an adaptive controller, and each leg can support the specified weight on any surface.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116784661","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}
