As the people age increases their physical functions degrade. So in order to provide physical support and speed up of their activities of the daily life many people are using the walking supporting devices. This device should support the wearer during the stance phase of gait. The model developed enables the Orthotic wearer to minimize the effect of hip extensor contraction to stabilize the knee and minimize the sense of security and to balance the body over the assistive device through the stance phase of gait. In this paper a driving circuit is designed, developed and controlled in a more implantable form with minimum resources and affordable cost. The driving circuit for the supervisory control of two stepper motors to lock and unlock the knee during stance phase of gait is designed. Here a Micro-controller is used to control the positions of two stepper motors for the desired positions. The designed circuit is stimulated using Proteus and MP LAB. The driving circuit developed is useful in assistive device to provide lock and unlock mechanism. The simulated results are checked with the hardware setup.","PeriodicalId":403612,"journal":{"name":"2011 International Conference on Process Automation, Control and Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129148117","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}

Because it does not need axes transformation and voltage decoupling blocks. DTC provides direct selection of voltage vectors according to the error obtained and allows direct and independent control of flux linkage and electromagnetic torque by the selection of optimum inverter switching modes. Based on the estimates of flux position and instantaneous errors in torque and stator flux magnitude, a voltage vector is selected to restrict the torque and the flux errors, within the torque and flux hysteresis bands. In the conventional DTC the circular locus is divided into 6 sectors and a total of 8 voltage vectors are used. However, the discrete inverter switching vectors cannot always generate exact stator voltage required to obtain the demanded electromagnetic torque and stator flux linkages. This results in production of ripples in the flux as well as torque. In this proposed work, neutral point clamped inverter is combined with 12 sector methodology. At present, the researchers have used all the 27 voltage vectors available in the 12 sector methodology. But in this proposed work the new switching table is constructed by using only 12 voltage vectors which includes large, medium and zero voltage vectors. The usage of 12 voltage vector gives satisfactory performance as compared to usage of all the 27 voltage vectors. The performance of the proposed work is also compared with classical DTC and 12 sector methodology with 27 voltage vectors. The simulation is performed in MATLAB / SIMULINK environment.","PeriodicalId":403612,"journal":{"name":"2011 International Conference on Process Automation, Control and Computing","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131809511","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}
