The proposed torque sensor enables to measure the rotational torque value while it decouples the external Force/Torque loads without any complicated computing procedure. To measure the joint torque, just two capacitive transducer cells are used. These two cells are located in the opposite sides of each other, which compensates the cross couplings of the torques when external Force/Torque loads are applied. To simply the manufacturing process, the proposed sensor is designed to be composed of three plate-shaped parts and a single printed circuit board (PCB). Lastly, the developed torque sensor is manufactured and its performances are experimentally demonstrated.","PeriodicalId":154457,"journal":{"name":"2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM)","volume":"1986 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130533267","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}

Also, we describe the design of bang-bang controller for θ-axis that is required for developing 3-axial controller. The inchworm mobile mechanism is composed of 6 piezoelectric actuators (PAs) and a pair of electromagnets (EMs). If one EM is fixed to a ferromagnetic floor, then another EM can position the X, Y, and θ axes by 6 PAs. In a previous study, we have developed 3-axial proportional-integral-derivative (PID) controls with a 50 nm resolution for the mechanism with 4 linear encoders to measure the 3DoF motion of the free magnet precisely However, we concluded that we require over 100 ms of settling time because of mutual coupling effects among the X, Y, and θ axes when using the PID controller. To be robust against the disturbance and also reduce settling time, we developed a new servo controller in this study. To achieve sufficient working efficiency, we aimed at establishing of 3-axial servo control on the nanometer scale that can realize a ±0.5 μm positioning repeatability, and less than 10 ms of settling time over a 50 μm×50 μm positioning range.","PeriodicalId":154457,"journal":{"name":"2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121929959","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 concept includes a DC motor, a gear transmission, a drum and a pull cable. The force-velocity characteristic of a commercial rowing machine was modeled by a fourth-order mechanical admittance, and its parameters were identified from actual exercise data by a collocation method. The admittance controller is related to, and an extension of the natural admittance control proposed by Newman. The controller of this paper is able to achieve any desired target admittance for the electromechanical system at its mechanical (user) port, as long as the admittance is strictly proper. A fourth-order mechanical admittance was identified by the collocation method, with very good agreement to the data. The identified admittance was subsequently used as the target admittance of the electromechanical control system. A scale-size prototype was used to test the controller in a realtime experiment. Achievement of the target admittance was verified by simulating its response to the force profile of the experiment. The resulting velocity was in close agreement to that recorded from the experiment.","PeriodicalId":154457,"journal":{"name":"2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115750216","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 new method, flying touch algorithm is introduced to control the gap between upper and lower roller for reducing scratches. In the flying touch method, the uniformity of coil can be debased due to variation of reaction force between rollers and steel plate. Therefore, the robust control algorithm and force estimation method is needed to apply flying touch method to hot rolling process. This paper introduces sliding mode control with sliding perturbation observer (SMCSPO) in flying touch hot rolling process.

The challenging task is to correctly estimate the region of the object of interest. The proposed system is implemented using the following framework for estimating the region of the object. First, the robot automatically estimates the object region based on user input. Second, the user can intervene by interactively drawing and erasing the estimated region while the system sequentially updates the estimation method based only on the user's correction. The advantage of this system is that only limited inputs are required from the user, a feature that is useful for handicapped users. Moreover, we introduce (1) graph cuts, comprising “HyperPixels” and three-dimensional information, to enable the system to recognize the rich features around the user-specified region for robust segmentation, (2) interactive correction of the automatically estimated object region while the system calculates good graph parameters for the correct estimation, and (3) recall and use of the learned parameters for the estimation based on the database of features around the clicked point.","PeriodicalId":154457,"journal":{"name":"2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127541262","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, automating all types of construction machinery is difficult because some operations require human skill and judgment-that is, professional skills-for realizing optimal work efficiency. However, the lack of competent professionals because of the decreasing and aging population in Japan is an emerging societal problem and is leading to concerns such as deterioration in workplace safety and difficulty in transferring professional skills. This study proposes human skill evaluation and assesses human skills through the application of control engineering. The human operator is analyzed as a nonlinear controller comprised of a proportional-integral-derivative (PID) controller and a PID parameter tuner. The parameters of this database-driven PID controller are tuned using data (i.e., reference signals, input signals, and output signals) obtained from operation.

To guarantee good control performance in the presence of both repetitive and non-repetitive disturbances, the ILC input and the feedback controller are optimized simultaneously in each iteration. Considering constraints from the input saturation, the ILC convergence requirement and the closed-loop stability, the controller design is formulated as a convex optimization problem. The influence of disturbance uncertainties is also incorporated into the optimization problem in the form of chance constraints. To reduce the complexity of the problem, special techniques such as relaxation and projection on convex sets are introduced to make the algorithm more efficient. The effectiveness of the proposed algorithm is verified by simulations conducted on a four-room testbed system.","PeriodicalId":154457,"journal":{"name":"2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116458153","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}
