The system handles three basic parameters for each client: economic solvency, payment capacity, and guarantees for the recovery of the overdraft. The system is flexible, which means that it is easy to modify or to incorporate rules in the knowledge base. The system is automatic, so there is no need for any human intervention in the decision-making process. All the information necessary is taken from the banking entity's information services network. The system performs a personalized treatment of the operations between the client and the bank, based on heuristics, just as an expert human would.<<ETX>>","PeriodicalId":384081,"journal":{"name":"15th Annual Conference of IEEE Industrial Electronics Society","volume":"161 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":"115413543","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}

However, the amount and direction of compliance must be controlled before the robot can be used in actual applications. The authors have developed an active compliance controller that uses force sensors on the wrists of the robot to determine the contact forces acting on the end effector. The sensors feed this information to the trajectory generator of the robot controller. The controller achieves high-speed control (the sampling time is 1 ms) by performing all control operations in parallel using two MB8764 digital signal processors. The stability of the control was analyzed for joints having an arm that is not rigid. The force control can be stabilized by keeping the force feedback gain reasonably small.<<ETX>>","PeriodicalId":384081,"journal":{"name":"15th Annual Conference of IEEE Industrial Electronics Society","volume":"48 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":"115432261","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 experimental set-up imitates a joint of an industrial manipulator. The control system is implemented around a digital signal processor, which is used to calculate the voltage to be applied to the servo motor. The control algorithm aims for the minimization of a performance index which is chosen as the norm of the tracking error over a future control horizon. For the prediction of the future output, a very simple approach with a physical meaning is followed, and it is shown that this results in the same predicted values as an optimal predictor widely reported in the literature. The experimental results presented show that highly accurate trajectory following is possible in spite of the very simple structure assumed as the model of the servo motor and its nonlinear load.<<ETX>>","PeriodicalId":384081,"journal":{"name":"15th Annual Conference of IEEE Industrial Electronics Society","volume":"80 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":"131571497","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 procedure uses the finite element method for the analysis of the magnetic field in various driving current conditions. This includes the analysis of the combined effect of the earth's magnetic field and other time-varying magnetic fields, the digitizing of the nonlinear conditional variation equation for ease of digital computation, and the fast Fourier transform for calculating output signals. The procedure also features computer-aided optimum design software for the magnetic field. The system has been implemented with a single-chip microcomputer which can determine the optimal driving current for the magnetometer online in real time. Experimental results show that that the procedure is significantly better than traditional ones.<<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":"114640538","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 power transfer mechanism of the proposed converter is different from that of such resonant-type converters as the resonant converter and quasi-resonant converter. The VAr (volt-ampere reactive) rating of the resonant capacitor of the proposed converter is very small compared with that of the resonant-type converter. The applied voltages to all the devices are limited to the supply voltage. This converter can operate in both constant and variable frequency with simple control. The basic operation of the proposed converter is described.

With a decreased amplitude, i.e. half of the optimum, the dynamic range is widened to the range of 0.2 m to 1 m; the standard deviation and the repeatability are less than +or-1.6 mm and +or-2.8 mm, respectively.

It also allows variable time steps, which is useful in long-time simulation study.

The developed navigation system comprises: (1) world model construction with three levels of hierarchy (building, corridor, and room); (2) two efficient techniques to plan a collision-free path to a specified goal within a known environment (in-room planning and corridor and building planning); and (3) control of the robot while executing the chosen path after abstracting the geometrical information along it from the related world model.
