In the SLAM problem, a robot sometimes loses its proper observations then the estimation accuracy deteriorates. In this paper, to remove the effects of unordinary observations, we propose a novel SLAM method considering unordinary observation based on Mahalanobis distance. The proposed method detects the unordinary observations by comparing the observation values with its estimation and determines the weight of these observations. The convergence of the state error covariance matrix is proven. In experimental validation, we show that the UAV state and environment information can be estimated with the proposed method.","PeriodicalId":167635,"journal":{"name":"2016 55th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130753343","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 detail, the proposed scheme is based on the stator flux oriented control (SFOC), and it consists of a Sequence Component controller (SCC) and a unique PI with ANN (PI-ANN) hybrid controller. The main objectives of the suggested scheme are to regulate independently the output active and reactive powers of DFIG and to diminish significantly harmonics in the rotor current during the unbalanced grid voltage dips. Numerical simulations, including considerations on sudden changes of reference values for the powers and the random alteration of wind speed, are performed in MATLAB to evaluate effectiveness of the proposed scheme. Furthermore, detailed comparisons between simulation results under the unbalanced voltage dips, obtained with the traditional PI method, PI with fuzzy logic (PI-F) hybrid technique and suggested PI-ANN scheme, also are illustrated to validate the salient performance of the presented control structure.","PeriodicalId":167635,"journal":{"name":"2016 55th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114218267","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 platoon driving of the welfare vehicles may become one of the effective leading methods of patients. Although the platoon driving systems for automobiles were widely studied assuming a straight road which has good visibility, the systems for welfare vehicles have been scarcely tried in a narrow corridor corner of care facilities. It is a reason of difficulty that the radius of curvature on the driving trajectory is very small and the pathway is complicated in the buildings. There are two issues for the platoon of welfare vehicles to drive in the narrow space. One is to design the precise steering controller keeping safe inter-vehicle distance. The other is to construct the robust controller which suppresses the influence of the parameter variation of the vehicle. This paper aims to design robust platoon driving control of welfare vehicles. The proposed controller consists of the longitudinal control and lateral control using MEC with the adaptive target tracking considering the curvature of the wheel track of the preceding vehicle. In driving experiments in a narrow corridor corner, the tracking error of proposed method is drastically reduced to 15% or less.","PeriodicalId":167635,"journal":{"name":"2016 55th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117340483","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 previous behavioral analysis studies, it is possible that the analysis result is different from the behavior pattern that insects intended originally because we define behavior patterns statistically using the amount of movement and velocity calculated from trajectory. Therefore, we analyze the behavior state transition at high resolution from the command neuron side signal. In other words, estimating behavior from muscle potential information can analyze behavior more quantitatively than analyzing behavior from trajectory. Thus, it is possible to properly elucidate the behavioral expression mechanism or the behavior selection process. Moreover, it allows us to understand the behavior pattern that insects actually selected. We focus on the odor source searching behavior of silkworm moths, and we estimate three types of behavior: forward moving, left turning, and right turning using a Support Vector Machine (SVM) approach. We employ flight muscle electromyograms (EMGs) whose motor commands were assumed to be generated in the same ganglion as the behavior that was estimated. Flight muscle EMGs of silkworm moths were measured in a free walking state by using a locomotion-measuring instrument named 3 DOF servosphere. We carried out simultaneous measurements on nine silkworm moth individuals, estimated the behavior patterns from the experimental data, and demonstrated the effectiveness of the method.","PeriodicalId":167635,"journal":{"name":"2016 55th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127123519","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}

Its performances to sudden changes in the load are evaluated though extensive simulations. These results show that the digital controller can realize the performance of an analog controller at a sampling frequency that can be much lower than those currently prevail, which may be advantageous in terms of reduced computational requirements and power consumption.","PeriodicalId":167635,"journal":{"name":"2016 55th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125595914","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}
