The method is based on the \"recursive convolution\" with the forcing terms modeled by nth order polynomials of time. Exact solutions are obtained if the system is linear, time-invariant and the forcing terms are polynomials of time. Several examples, including a typical step-up switching power supply, are described.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127931945","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 authors consider the planning of the input torques and the trajectory of the manipulator so as not to excite the vibration of the flexible beam. The equations of the motion of a two-link manipulator with a flexible beam are derived. On the basis of the dynamic equations, the optimal input torques, which accomplish the desired end-position of the manipulator and the diminution of the vibration of the flexible beam, are calculated by using a numerical algorithm for the optimal control of the nonlinear equations. As the equation of the vibration of the flexible beam implies that the acceleration of the end-point of the manipulator excites the vibration, the authors consider an optimal trajectory planning so as to minimize the end-point acceleration of the manipulator. The validity of the optimal input torques and the optimal trajectory are demonstrated by computer simulations and experiments for an air-driven robot arm.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128056846","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 new vector calculator is presented which provides an instantaneous value of the 'balanced' fundamental real load current needed to support the real power requirements of the three-phase load. The injected current reference is derived from the difference between the real current and the actual load current. Fundamental VAr or power factor compensation can be carried out at the same time.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133338170","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 process utilizes several gray scale images captured by a fixed camera with six light sources at different positions. The positions of the camera and light sources are calibrated. The two-dimensional shadows casted by an object are extracted from the images. The geometrical relationship between the light sources, the camera, and the corners of the shadow boundary are used to obtain three-dimensional coordinates of the corners of the polyhedral in a world coordinate frame. A volumetric representation of the shape of an object is then possible.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133430877","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}

Using these techniques, the authors can obtain magnified images with higher quality.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133787892","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}

Three estimation schemes are formulated according to the representation of the disturbance torque and processing of the observer states. In addition to the disturbance torque, all the schemes deliver an estimation of the motor speed. Steady-state accuracy and dynamics of the schemes are analyzed in nominal conditions, identifying the scheme with the best performance. The effects of variations in the motor parameters are also analyzed, finding that a proper modeling of the motor makes the steady-state estimation of the disturbance torque insensitive to any variation. As a test, the schemes are applied to a sensorless DC drive for both compensating for the disturbance torque and closing the speed loop. The responses obtained with the best-performance scheme are reported.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115727711","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}

Therefore, if one tries to make the plant output track a reference output exactly, one must identify initial states and parameters of the plant, and synthesize control signals by taking account of the effect of the initial states of the plant. In this paper the authors propose a quick identification method which can identify initial states of the nonlinear plant as well as the time varying parameters, and propose a nonlinear robust controller, consisting of a simulator, that is, a physical model of the plant with the same structure as the object plant, with a computing predictor network which predicts dynamics of the plant from the information of internal states of the simulator. Validity of the proposed control system was verified by a simulation study in which an arbitrary control performance of the system for a nonlinear time-varying plant was verified.<<ETX>>","PeriodicalId":132101,"journal":{"name":"Proceedings of IECON '93 - 19th Annual Conference of IEEE Industrial Electronics","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114594108","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}
