The RTU architecture was chosen to be distributed in order to reduce cabling costs and cabling difficulties, caused by the several hundreds of signals that must be connected to the acquisition points (plant interface close to equipment terminals) in a factory. This also provides the means to distribute the processing power between all the units that compose the RTU, and to create two different EMC immunity requirements, one for the field units and other (less restrictive) for the central unit, using one high immunity communication medium as the connection path between all the system components (fiber optic).","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126327853","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 feasible test is carried out using a 500 kVA active PWM power converter designed for the unique considerations mentioned above. It is verified that these new considerations are effective to minimize higher harmonic current components flowing into the utility-grid AC line. Furthermore, this experimental work provides highly efficient AC/DC power converter characteristics under unity power factor correction and sinewave line current shaping schemes. Finally, this paper indicates that the optimum PWM pattern can be applied to the voltage source converter and has an excellent switching performance as compared with conventional PWM modulation.","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130148805","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 MRAC was originally designed for the unknown plant which should be linear and completely disturbance free. Practically, since real plants have nonlinearities, such as disturbances and unmodelled dynamics, the performance of the controller is worsened. This paper describes an error feedback model which is a reference model with the output error feedback, for improving robustness and stability to nonlinear characteristics. The proposed model can be used for MRAC using the measurable output of the plant and the states of the proposed model. Experiments on an SR (switched reluctance) motor have been done in order to illustrate the validity of the proposed controller.","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127645018","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 operating principle of a new inverter circuit is presented together with its power regulation characteristics on the basis of its computer-aided simulation analysis and its experimental results.

The availability of these previously mentioned services is different for different service environments. To provide these services, various access facilities used by the end users to access to telecommunication networks must be made available to all of the users. The (public) networks covering different parts of the world must be interconnected so that the global communication can be implemented, that is, the so-called global network must be realized.

The model uses a charge-control approach according to the HEFNER model. The effect of the transient chip-temperature on different physical parameters is defined by the thermal model. The numerical realization is made on the basis of nodal analysis and a linearization according to the Newton-Raphson method. All equations are implemented in C-code and combined with the simulator source code, using the PSpice device equation option. As a result, an internal model is created. Due to the thermal network, the IGBT has become a four terminal device. It can be applied to various thermal and electrical circuit topologies. A transient simulation of the device temperature allows short circuit or overload conditions to be studied in detail.","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116294782","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 key issue of the DTC is the strategy of selecting proper stator voltage vectors to force stator flux and developed torque within a prescribed band. Due to the nature of hysteresis control adopted in DTC there is no difference in control action between a larger torque error and a small one. It is better to divide the torque error into different intervals and give different control voltages. A fuzzy controller has been introduced to deal with this issue. However there arises the problem that the number of rules is too high. This will affect the speed of fuzzy reasoning both in simulation and hardware implementation. In this paper a stator flux angle mapping method is proposed to reduce the rule numbers while keeping the performance of the system satisfactory. To test the fuzzy control strategy a simulation platform using SIMULINK was built which includes an induction motor d-q model, inverter model, fuzzy controller and the stator flux and torque estimator. The simulation results verified the new control strategy.","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125693489","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}

They describe an approach for simultaneous learning of a world model, and learning to navigate from a start position to a goal region on the world. These two learning abilities may be seen as cooperating and enhancing each other in order to improve the overall system performance. It is assumed that the robot knows its own current world position. It is only additionally assumed that the mobile robot is able to perform sensor-based obstacle detection (not avoidance), and that it is able to perform straight-line motions. Results of simulation experiments are presented that demonstrate the effectiveness of the approach to navigate a Nomad 200 mobile robot.","PeriodicalId":134474,"journal":{"name":"ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125694471","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}
