Information contained in the value of measured rotor speed has to be obtained from other available signals, especially the stator input voltages. However, the actual output voltage of the voltage source inverter differs from the reference value. This influence is especially important in low speed region where the error in calculated flux values might cause not only reduced pull-out torque and additional losses of the machine but also the unstability of the drive system. While one would like to avoid measurement of actual stator voltages because of its complexity and higher cost of the system, additional performance improvement in very low speed region can only be achieved with exact knowledge of voltage. But this can only be obtained by using measurements. The main goal of this paper is to present advantages of stator voltage measurements in low speed region of speed sensorless drives over cost effective solutions using dead time compensated inverter.","PeriodicalId":193510,"journal":{"name":"IEEE International Conference on Industrial Technology, 2003","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115660893","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}

Saikawa","doi":"10.1109/ICIT.2003.1290746","DOIUrl":"https://doi.org/10.1109/ICIT.2003.1290746","url":null,"abstract":"This paper reports the development of a pneumatic artificial muscle based on biomechanical characteristics. A wearable device and a rehabilitation robot which assists a human muscle should have characteristics similar to those of human muscle. In addition, because the wearable device and the rehabilitation robot should be light, an actuator with a high power/weight ratio is needed. At present, the McKibben type is widely used as an artificial muscle, but in fact its physical model is highly nonlinear. Further, the heat and mechanical loss of this actuator are large because of the friction caused by the expansion and contraction of the sleeve. Therefore, the authors have developed an artificial muscle tube in which high strength Kevlar fiber has been built into the silicone tube. However, its contraction rate is smaller than actual biological muscles. In this study, an artificial muscle with a high contraction rate was developed by using natural latex rubber as the tube material. Since the elasticity of this material is smaller than that of silicone, characteristics similar to those of an actual muscle can be expected. Experimental results demonstrate the effectiveness of this artificial muscle regarding its fundamental and biomechanical characteristics.","PeriodicalId":193510,"journal":{"name":"IEEE International Conference on Industrial Technology, 2003","volume":"185 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122752491","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}
