Improvement of the disturbance suppression performance is a general and important index in the FB controller design to realize the precision performance. However, since the stability of the FB system generally limits the disturbance suppression capability, improvement of both the disturbance suppression and the stability should be difficult to achieve. In this study, therefore, a FB controller which considers the stability margins (i.e. gain and phase margins) is designed on the basis of a circle condition on the nyquist diagram, to achieve the required disturbance suppression with the desired stability margins. Effectiveness of the proposed approach has been verified by numerical simulations and experiments using a prototype of linear motor-driven table systems.","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":"91004214","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 event-driven control of a mechatronic system was implemented on a field-programmable gate-array (FPGA) platform. The supervisor provides robust, safe, and transparent control, where the FSM defines all the possible directions for implementation. In order make supervisor more transparent, the FSM was divided into three main parts, with three main colours (green, yellow and red - semaphore). These colours indicate the condition of the system. The supervisor was upgraded with a Graphic user interface (GUI) with indicators that directly show the state of the FSM. The GUI includes additional logical I/O signals, in order to make system more useful. The supervisor is executed parallel with the basic motor control on the FPGA. This paper presents the robust current controller of the brushless ac (BLAC) motor, upgraded with a classical PI velocity controller. The application of the proposed ECA-based method is illustrated using the example of the FSM motion control of a BLAC motor with integrated I/O signals.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"6 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":"75175184","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}

For the realization of haptic transmission, a master and slave system is utilized and these systems have to be connected via network in actual applications. In communication via network, it is known that a communication delay, packet loss and jitter are undesirable effects on control system occur. Moreover, large burst loss may also occur in wireless mobile communication by changing access points for the expansion of the range of communication. In order to realize vivid haptic transmission through network, hard real-time property and transfer reliability are demanded. There are many conventional studies which focus on communication delay, on the other hand, studies about the reliability of data transfer on haptic communication are not conducted so much. Therefore, this study pays attention to the burst loss by hand over in wireless haptic communication. To tackle this problem, this paper proposes new haptic transmission method which uses multiple-routes. By using the method, the effect of the burst loss is decreased in communication with the single route. The viability of the proposal is shown by two kinds of experimental results of bilateral control. The one is stationary system, and the other one is mobile system. As for the experiment of the mobile system, this study uses the newly-developed mobile-hapto.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"142 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":"74766068","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 gradient method is well known as one of the conventional methods to estimate the flows, and then the spatial and temporal derivative of the images are used in the method. Since the color images have richer information than the monochrome ones, they should contribute for estimating the more precise optical flows. In our approach, the color derivative vector (CDV) is introduced to bring out the information in the color images for the optical flow estimation. The CDV is derived from the derivatives of color images, and the optimal CDV provides the concrete weighting values of the RGB data. The optimal CDV is obtained with using the eigenvalues and the eigenvectors of the matrix consisting of the spatial and temporal color derivatives.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"55 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":"73830740","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 context, we study multimodal haptic interfaces, i.e. the fusion of force-feedback, with other tactile information such as temperature or pressure. First results support the proposition that such multimodal haptic devices can help improve surgeon's dexterity and motion control. In order to strengthen this point, we investigate the psychophysics of thermal perception. This paper presents a device for temperature feedback that can be integrated in a multimodal haptic console. A finger sized tactile temperature display able to generate temperature gradients under the fingertip is presented along with first measurement results.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"36 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2012-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74088811","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, the endoscopic forceps has two big problems. First is the endoscopic forceps has friction, and it nonlinearly changes depend on posture of the endoscopic forceps. The friction cause deterioration of operation performance. Second is the endoscopic forceps has only 1-DOF for grasping motion. Therefore, in this paper, Actively-controllable endoscopic forceps is developed. This endoscopic forceps has 2-DOF which are for grasping motion and bending motion. By bending motion, the endoscopic forceps can keep or change posture by itself. In addition, friction associated with changing posture of the endoscopic forceps is modeled by least-square method. Finally, the friction models are applied to bilateral control system. Friction of the endoscopic forceps is compensated, and improvement of operational performance is achieved.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"30 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":"82026601","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, the original haptic senses of soft environments are so small that it is difficult to recognize. In that case, the recognition of the haptic senses becomes easier by scaling force information in the frequency domain. In this paper, the bilateral control is proposed which can scale only force with arbitrary frequency domain. In a conventional method, force information with the arbitrary frequency domain is scaled with online Fourier transformation. Thus, there is a delay in the conventional method. In the proposed method, only slave force information is scaled by using the complex number as a scaling rate. The complex number scaling rate contains a function of a filter. As a result, the proposed method had no delay and could scale force with the arbitrary frequency domain. Stability analyses with root locus showed that the proposed method were stable. Frequency characteristics were also analyzed. Validity of the analyzed frequency characteristics was confirmed through experiments. In addition, the validity of the proposed method was shown through penetrating experiments by enhancing force at the instant of penetrating through a film.","PeriodicalId":6439,"journal":{"name":"2012 12th IEEE International Workshop on Advanced Motion Control (AMC)","volume":"9 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":"79687012","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}
