The current paper considers path following for differentially flat systems. In this case the dynamics of the system can be projected along the path to a single input system, resulting in a free end-time optimal control problem. We propose to rewrite the problem in terms of the velocity along the path and the path itself. This way, we arrive at a fixed end-time optimal control problem that can be solved efficiently by interior-point solvers. Two challenging examples, a truck-trailer parking simulation and a quadrotor mission, illustrate the efficiency of the problem formulation and the practicality of the developed software.","PeriodicalId":448152,"journal":{"name":"2013 IEEE International Conference on Mechatronics (ICM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129186400","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}

A narrow and small personal mobility robot (PMR) requires control of its posture in order to achieve quick turning and high acceleration. However, in the conventional control approach that uses the posture angle as a controlled variable, the zero moment point (ZMP) cannot be set to the desired point if an unknown disturbance force acts on the PMR, if the center of gravity of the PMR fluctuates, or if the conditions between the tires and the road surface change. In the present paper, a novel control method using feedback compensation with an unstable pole is proposed in order to achieve the desired ZMP at the steady state. The proposed controller changes the control input for the actuator of the posture control to zero in order to achieve the desired posture angle. The effectiveness of the proposed approach is verified experimentally using a prototype PMR.","PeriodicalId":448152,"journal":{"name":"2013 IEEE International Conference on Mechatronics (ICM)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132135126","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 control targets of the general bilateral control are simply defined as the each position difference and the each force sum. On the other hand, the different control targets are defined in scaling bilateral control. In the proposed method, by introducing the drift function, the form of these control targets are unified. Then, the precision of position control is improved. In addition, the proposed one enables to realize some complex scaling bilateral control methods. In this paper, the proposed one is applied to micro-macro bilateral control and dimensional scaling bilateral control. When the proposed one is not utilized, the form of the these control targets are defined differently. Therefore, according to scaling bilateral control, the controllers need to be designed one by one. Utilizing the proposed one, the drift function only needs to be derived with the same controllers. In the experiments, it validated that the proposed one could be implemented. Moreover, it also validated that the precision of position control was improved with the proposed one.","PeriodicalId":448152,"journal":{"name":"2013 IEEE International Conference on Mechatronics (ICM)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116007707","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 storage and reproduction of human motion information, a motion-copying system was proposed previously. The motion-copying system is based on the bilateral control, and the stored motions which are obtained by the master-slave system can be reproduced by the slave. In the conventional method, however, precise motion reproduction can not be always attained because the slave reproduces the motion data which are acquired at the master. On the other hand, the proposed method stores the motion data at the slave, and the slave reproduces this data. In the proposed method, force, position, and acceleration reference at the slave are stored and reproduced. Furthermore, this paper analyzes the performances of the conventional method and the proposed method, and reveals that the proposed method shows the better performance with respect to motion reproduction than the conventional method. Finally, the validity of the proposed method is verified by some experiments.","PeriodicalId":448152,"journal":{"name":"2013 IEEE International Conference on Mechatronics (ICM)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117193766","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}

From the set of changeable and unchangeable requirements indicators are derived to assess the effort needed for the development of a new variant.
