An alternative tool used for fields-based evaluations of an induction machine is the finite-element method. Although useful, its computational complexity limits its use as a design tool. In this paper, a field reconstruction (FR) method for induction machine simulation is introduced The FR method utilizes a small number of finite-element evaluations to establish basis functions of normal and radial flux densities. The basis functions are then used to estimate the magnetic field under arbitrary stator excitation. Using such a tool, evaluation of fields and forces produced by the machine under alternative excitation strategies can be explored efficiently. Moreover, alternative fields-based derivation of stator/rotor excitation control can be explored.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128352917","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}

It often has the desired position reference. An industrial servo system has the limitation values based on each output of actuator and power amplifier. Hence, a high speed position servo system should keep the tracking control for the desired position reference within the limitation values. Moreover, an industrial servo system must realize the robust control against load torque and load inertia variation. An ordinary position servo system has the complicated control structure caused by the triple minor control loops. On condition of both load inertia variation and the saturation caused by current & voltage limitation, an industrial servo system sometimes has a large overshoot and an oscillated response. Therefore, for the desired quick position reference, it is difficult for a high speed position servo system to keep the robust tracking control against load inertia variation within each limitation of motor current and motor voltage. In order to overcome this problem, this paper proposes a new robust high speed position servo system considering current & voltage limitation and load inertia variation, which is based on disturbance observer. The experimental results confirm that the proposed system realizes the desired & quick & robust response keeping each limitation of speed, current and voltage on condition of both full load torque and three times load inertia variation.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116534250","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 physical support must be based on the individual's sensation and action. Then, real world haptics will be a key technology for the realization of human support based on the individual's sensation and action. Additionally, the preservation and reproduction of real world haptic information has been required for the purpose, since it may achieve the preservation of the individual's sensation and action. This paper proposes micro-macro bilateral control with respect to standardized modal space, in order to realize the physical support for the microscopical activities. In micro-macro bilateral control, the standard of the macro master system must be harmonized with the standard of the micro slave system. Then, in this paper, the standardization between macro master system and micro slave system is attained in the standardized modal space. Later, the reproduction method of real world force sensation by micro-macro bilateral control based on haptic storage is proposed to achieve the fundamental technology of the preservation of the individual's sensation and the microscopical action.

In contrary to the typical PI Fuzzy which requires minimum of two inputs variables, the proposed controller requires only one input. However the performance of the controller is not degraded. The reduction in the number of inputs minimized the number of fuzzy rules, tuning parameters and thus simplifies the overall fuzzy controller design. Furthermore, with single input, the input-output mapping can be presented as a simple control surface. In this case, it is mapped as a piecewise linear and can be realized by using a simple look-up table. As a result, a faster fuzzy calculation can be achieved using an inexpensive digital processor. A design example of the proposed controller for a single phase inverter is outlined. Using Matlab simulations, it can be shown that the proposed controller exhibits equivalent performance with the typical PI fuzzy controller.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116684822","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}

Both the input-side and output-side over- modulation modes have been studied and their limits of operation are derived. With output-side over-modulation, the maximum output to input voltage transfer-ratio with 6-step square wave output voltage is found to be 0.95 which is higher than the 0.866 intrinsic limit of the matrix converter. With input-side over- modulation the maximum voltage transfer-ratio is found to be 0.908 while still being able to control the power factor of the input currents. With simultaneous input and output-side over- modulation, a unity voltage transfer-ratio is achieved. This improvement in the voltage transfer-ratio in the above three cases is achieved at the cost of low frequency distortion in the output voltages and input currents. With simultaneous input and output- side over-modulation, a voltage transfer-ratio of 0.958 is achieved without significantly increasing the harmonics in the input currents and output voltages. Theoretical calculations are supported by experimental results on a laboratory prototype.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128685686","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 in M method, which is the most generally used velocity estimation method, velocity resolution becomes low due to the short sampling period. This leads to a limitation of the performance, especially in acceleration control using a disturbance observer which requires accurate velocity information. There are several velocity estimation methods to improve the resolution. These methods require a dividing operation. From point of view of resource sharing and resource utilization of FPGAs, implementing divider is not desired. In this paper, velocity estimation which does not require any divider is proposed to improve the velocity resolution in the short sampling period system.
