Particular attention is given to a system of this type using laser technology. Issues treated are the definition of external inspection, inspection apparatus construction, inspection and analysis, quality control management functions, main specifications, and system configurations. The most significant feature of this system is the easily comprehensible, hard-copy form in which the inspection data are presented.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"54 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":"114610247","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 respective shop coordinator, workcell planner, and workcell controller software is described. The function, structure, and behavior of the artificial-intelligence software are explained in detail. The implementation examples presented illustrate such key concepts of various domains as job shop and flow shop production; planning, control, and coordination; and object-oriented modeling, blackboard problem solving, and temporal reasoning. Results show that the concepts of the technology domain not only ideally match those of the application domain, but are also tractable and lead to applicable systems in the factory.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"35 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":"115065047","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 converter is autonomous in that it can be used as a self-sufficient entity. The particular application described is not exclusive: the converter can be used in any other application which can make use of its properties. The converter consists of a positive current feedback loop and a negative voltage feedback loop with a current feedback circuit in the current loop of a prescribed transfer function. This arrangement then provides for the infinite disturbance rejection ratio in electric motor drive systems in which the converter is used to force the effects due to the equivalent motor impedance to zero. Furthermore, it allows for additional synthesizing of appropriate (feed)forward gains to achieve zero order dynamics.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"45 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":"125046271","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}

This method creates a transient stress wave in the object under test by means of mechanical impact, while a suitable transducer detects wave reflections on the surface. Processing of the reflection signals enables deductions to be made concerning the subsurface conditions. Details concerning the design of a high-fidelity piezoelectric transducer specifically constructed to detect impact echoes on a concrete surface are described. Processing and analysis of the surface displacement signals are discussed. Results of preliminary laboratory studies designed to detect voids in various concrete specimens are presented. Cylindrical voids in plates up to 15 in thick have been reliably found using a discrete Fourier transform signal processing method.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"28 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":"128507347","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 incorporation of adaptive control facilitates converter operation within a constant commutation frequency, adding an implicit harmonic control to the intrinsic voltage regulation capacity of the VSS systems. The converter is characterized by online generation and good transient performance. The validity of this technique is confirmed by computer simulation. As a consequence of the system's behavior, a minimal-UPS structure is proposed for operation in parallel with the utility grid. The resultant power converter can operate as a reactive power compensator, an energy storage system, and an active filter for the line.<<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":"129311510","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}

Scheduling problems that are difficult to solve by an analytical method have been mainly solved by searching state space. However, the cost of solving the state-space problem is expensive. An assumption-based inference system that makes it possible to search state space effectively by the pair coils exchange method, and to avoid combinational explosion, was developed. To evaluate the approach, the system was applied to a steel production line for prototype use. It was confirmed that this system improved product quality.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"97 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":"132086924","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}
