Criteria for the selection of GTOs, design of snubbers, and adoption of GTO control are given. The advantages and drawbacks of the strategies used are discussed. Detailed experimental results concerning the GTO commutations and the snubber circuit are presented. The influence of important parameters, such as the load current, on the transient and steady-state voltage distribution on the GTOs is discussed. As series connection of GTOs is liable to be used in the high-voltage static converters utilized in rail traction systems, two industrial realizations are considered.<<ETX>>","PeriodicalId":384081,"journal":{"name":"15th Annual Conference of IEEE Industrial Electronics Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125541716","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}

Display pagers with a lot size of one are produced utilizing a state-of-the-art computer control system. Pagers are manufactured with shorter cycle times, higher quality, lower costs, and greater inventory turns than with traditional manufacturing methods. A key to the implementation of cost-competitive domestic manufacturing is an effective CIM (computer-integrated manufacturing) strategy. The demand for a zero-setup-time, lot-size-of-one, built-to-order automated manufacturing system required an advanced CIM system. Each pager is unique, with a special set of hardware and software customized to the end user. The CIM system supporting the database driven factory allows over 21 million combinations of product to be manufactured individually, one at a time. The CIM hardware and software architectures are described.<<ETX>>","PeriodicalId":384081,"journal":{"name":"15th Annual Conference of IEEE Industrial Electronics Society","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125633853","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 digital control law is derived so that the response of the digital control system is close to that of the continuous control system. The amount of computation for the redesigned control algorithm is almost the same as the amount of computation for the original nonlinear control algorithm. The redesign method provides satisfactorily stable results, even for a fairly large sampling interval. The algorithm was experimentally applied to a direct-drive arm with two degrees of freedom. Simulation and experimental results illustrate the effectiveness of the proposed redesign method.<<ETX>>","PeriodicalId":384081,"journal":{"name":"15th Annual Conference of IEEE Industrial Electronics Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130358329","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}

With this approach, it is possible to specify the command input response to an arbitrary reference model while keeping a strong robustness to system variations and a high suppression performance with respect to disturbances. These can be designed independently of the command input response. The TDOF method is generalized to unstable plants, and two types of practical parameterizations for the TDOF controller are proposed in order to design the speed and position servosystems, respectively. Their excellent control performances have been confirmed by experimental results. The application of one of the proposed servocontrollers to the motion control of robotic manipulators is described.<<ETX>>","PeriodicalId":384081,"journal":{"name":"15th Annual Conference of IEEE Industrial Electronics Society","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128812077","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}

Since both eddy current loss and hysteresis loss are frequency-dependent, a novel induction motor model with stator and rotor circuits expressed in different reference frames is presented to facilitate analysis. As the eddy current and hysteresis losses are ohmic, the stator and rotor eddy current losses can be represented by resistors across the stator and rotor magnetizing inductances. Necessary equations are derived to calculate the values of these resistors. Using the developed model and simulation equations, a simulation of a 250 HP squirrel cage induction motor was implemented. The proposed model is particularly suitable as a building block to generate a suitable PWM (pulse-width modulation) pattern that has minimum motor losses.<<ETX>>","PeriodicalId":384081,"journal":{"name":"15th Annual Conference of IEEE Industrial Electronics Society","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128037946","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 aim of the study was to introduce an innovative software technology to the field of natural disaster prevention. In the study, two simulation models for natural phenomena were adopted as examples: one was a geological problem involving the solution of a partial differential equation by the difference calculus to study the behavior of a wetting front in the ground caused by rain-water in time series, while the other was a seismological problem of computing multiple integrals in the calculus of variations to seek the distribution of dislocations in a fault plane as an elastic body. These examples were programmed in Fortran in the usual computer and then, according to the sequential algorithm, translated into the data-flow assembler. The computing time in the data-flow computer was approximately three-to-five times shorter than that of the usual medium-size computer of computing speed 3 MIPS (million instructions per second). Dynamic visualization of the computing process was realized using an image display directly connected to the memory of the data-flow computer.<<ETX>>","PeriodicalId":384081,"journal":{"name":"15th Annual Conference of IEEE Industrial Electronics Society","volume":"667 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122546818","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}
