A statistical based computing algorithm is proposed in order to avoid the division by zero. Three basic algorithms have been considered in order to establish the optimum solution. The study of the speed and rotor resistance estimator has been performed together with a Gopinath flux observer. Hence, the rotor flux, rotor speed and resistance have been estimated using only the electrical feedback magnitudes of the motor: the stator voltages and currents. The estimated rotor resistance is applied to the input of the flux observer and voltage compensator blocks. The simulation results prove the simplicity and the performance of the estimator based only on the electromagnetic phenomena inside the motor.","PeriodicalId":360541,"journal":{"name":"Proceedings of 4th IEEE International Workshop on Advanced Motion Control - AMC '96 - MIE","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126137275","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}

In this paper, novel approaches for the design of SMC based on the selection of a Lyapunov function are proposed for motion control applications that evade these problems and are easily implementable. A general criterion is established for stability and chattering elimination. Two novel schemes are proposed for the estimation of the equivalent control to avoid the computational burden. Simulation studies carried out on a direct drive arm indicate that the proposed approaches are a good candidate for motion control applications.","PeriodicalId":360541,"journal":{"name":"Proceedings of 4th IEEE International Workshop on Advanced Motion Control - AMC '96 - MIE","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127137086","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}

This robot hand with three fingers can simultaneously grasp and rotate a cylindrical body. The driving characteristics of the robot hand were examined experimentally under various conditions. It was confirmed that high torque was obtained when the optimum contact angle and contact force of the ultrasonic motors were used. The reduction of the output torque is small even when the diameter of the rotational body deviates from the designed value.","PeriodicalId":360541,"journal":{"name":"Proceedings of 4th IEEE International Workshop on Advanced Motion Control - AMC '96 - MIE","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128924657","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 vehicle has a pair of driving wheel which configuration has a offset distance between a steering axis and a wheel axis. The wheel of this style is known as a nonholonomic system and is usually used for a caster wheel. In the case of proposed vehicle, a wheel of this style is used as a driving wheel by actuating a wheel axle and a steering axle independently. We first present a concept of the offset steered driving wheel\", then describe kinematic models of the single driving wheel and a holonomic vehicle with proposed driving wheels. To avoid the nonholonomic characteristics of the wheel, we have introduced a control method in which an orientation of the wheel is neglected to be controlled. Therefore only translational velocities of the steering axle of the wheel are controlled so as to realize reference velocities. By using proposed wheel mechanism and the control method, the wheel can achieve a reproduction of caster motion. The vehicle with a couple of proposed driving wheels achieves omnidirectional and holonomic movements. Finally, proposed control methodology which based on kinematic models of the driving wheel and the vehicle has tested by a prototype vehicle. Experiments of the prototype vehicle have shown successful performances.","PeriodicalId":360541,"journal":{"name":"Proceedings of 4th IEEE International Workshop on Advanced Motion Control - AMC '96 - MIE","volume":"17 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120910700","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}
