This modification is based on the premise that precise sonar model is not required for accurate map building. We use uniform random distribution approach to replace the probabilistic model of sonar sensor. Problem of localization of the mobile robot is also discussed as it is very important for the precise mapping of the environment. For this purpose we used odometry measurements processed by Extended Kalman Filter for the robot localization. It is shown that this method gives precise maps of an environment in Player/Stage simulator, and also with real world scenarios.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"31 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84357094","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}

With the improved energy storage systems and control algorithms, hybrid vehicles can further gain on the applicability and consequently on the popularity. In this paper, a design and control of the elements of the hybrid vehicle propulsion system, with an emphasis on supercapacitor as the peak energy storage unit, is presented. The propulsion system is dimensioned for light delivery vehicle. In order to simplify design and testing, a laboratory test rig was built rather than using the complete vehicle. Trough simulations and experiments a significant improvement of the properties of energy storage system is confirmed after adding the supercapacitor to the battery. The experiments also confirm the advantages of energy flow management based on the stabilization of the common DC bus voltage.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"59 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80534963","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}

We estimated joint stiffness in a female Japanese monkey (Macaca fuscata) during arm reaching movements and carried out a numerical simulation. The estimated stiffness was high at movement onset and movement end, and decreased at the mid-point of the movement. These characteristic patterns were reproduced by the numerical simulation using a 2-link 6-muscle arm model and an approximately optimal feedback control. Although the arm model was a redundant system with multiple dimensions of freedom, the optimal control was able to solve the redundancy problem by optimizing a task-relevant cost function. We suggest that the brain may control the body according to a similar optimal control law.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"2004 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89523929","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}

Since biped humanoid robots balance themselves on a limited area with foot soles, the detection of external force is important to realize for a stable balance controller for humanoid robots working in a real environment. In the proposed observer, the external force is estimated using inertial sensors and foot force sensors based on simple but efficient modeling of the forces applied to the robot. This paper also shows the experiments of the proposed external force observer using a real humanoid robot HRP-2.

A time-delay compensation method based on network disturbance (ND) concept and CDOB has been proposed and applied to various control systems. It compensates time-delay effect without using time-delay model and the effectiveness is equivalent to that of Smith predictor. Furthermore, it works even when time-delay value is unknown, since it does not need time-delay models. In past works, some design methods of time-delay systems with CDOB have been studied basically by using Nyquist diagram. However, detailed design methods of the transient characteristics have not been researched well due to the characteristics of Nyquist diagrams. In other words, we have not addressed design methods based on detailed pole placements studies in order to arbitrarily design the transient characteristics. In this paper, we study a design method of time-delay systems with CDOB based on pole placements by using Pade approximation. The detailed design of the transient characteristics is accomplished by the analytical results. The adequacy of the presented design method is validated by simulation studies.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"107 22","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91408218","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}

General Class-B power amplifier cannot be used for driving high-power actuators because of power efficiency. On the other hand, due to PWM, typical Class-D power amplifier generates switching noise as well as desired current, though the power efficiency is very high. The switching noise cased by PWM inverter degrades the control performance of the motor. In short, typical Class-B and Class-D power amplifiers are not suitable for advanced motion control. By using Class-G amplifier, problem of both power efficiency and noise is able to be solved. Therefore, Class-G amplifier enhances the control performance of current controller for motion control. Driving test of Class-G power amplifiers is conducted. The current controller and force control system are implemented in FPGA. By the experiments, validity of the current control and force control with Class-G power amplifier is verified.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"24 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73886588","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}

If the landing of the biped robot is unstable, the robot may fall down. Therefore, it is necessary for the biped robot to realize stable landing. In order to achieve the stable landing, force controller should be implemented at the moment of landing. Since force control enables the sole to softly contact the ground. If the landing state becomes stable, control method needs to change position control for the biped robot moving. In other words, the controller should be switched according to the contact condition between the sole and the ground. Therefore, switching control method which consists of position control and force control is proposed. Zero Moment Point (ZMP) is used as index to switch the controller. Position control is applied when ZMP exists in the area around the center of the foot. Force control is used when ZMP exists around the edge of the foot. The validity of the proposed method is confirmed from the simulation results by using the model of inverted pendulum with a sole.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"22 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88792697","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}
