The WEC system includes four main components: a frame structure; a buoy with guiding shaft; a VSM with a ball screw, two pre-tension springs, motor and gearbox; a supplementary mass coupled with linear generator. In the first embodiment, the up and down motion of the buoy under heave wave is converted to linear motion of the supplementary mass. The mass will oscillate two coils coupled with it. The oscillation of two coils in two magnetic walls will create electricity by the principle of electromagnetic induction as a linear generator. In the second embodiment, two pre-tension springs will create a negative stiffness effect acts on the oscillation of the mass thus its motion is amplified. In the third embodiment, the VSM with the motor can control the motion of the ball screw thus the displacement of the spring will be changed to increase the restore spring force which can boost the motion of the mass. The specification of the system is proposed and studied. The working principle is analyzed. The mathematical model is then derived to investigate the system operation. Simulation has been done to evaluate the operation of the system.","PeriodicalId":309525,"journal":{"name":"2019 23rd International Conference on Mechatronics Technology (ICMT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125798814","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}

Indeed, the classical model-free approaches (such as Gradient Ascent or Extremum Seeking algorithms) have intrinsic limitations. To overcome those limitations, Machine Learning techniques, in particular, the Reinforcement Learning, are attracting more and more attention in the particle accelerator community. The purpose of this paper is to apply a Reinforcement Learning model-free approach to the alignment of a seed laser, based on a rather general target function depending on the laser trajectory. The study focuses on the alignment of the lasers at FERMI, the free-electron laser facility at Elettra Sincrotrone Trieste. In particular, we employ Q-learning with linear function approximation and report experimental results obtained in two setups, which are the actual setups where the final application has to be deployed. Despite the simplicity of the approach, we report satisfactory preliminary results, that represent the first step toward a fully automatic procedure for seed laser to the electron beam. Such a superimposition is, at present, performed manually.","PeriodicalId":309525,"journal":{"name":"2019 23rd International Conference on Mechatronics Technology (ICMT)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127464702","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 specimen is placed onto a sample holder which is manipulated by a motorized stage. In this study, a specimen stage for Transmission Electron Microscopy is designed. The stage consists of a sample holder and four motorized axes for three linear motions and one tilt motion. Especially, the specimen put in a vacuum environment must be separated from the atmosphere. The specimen stage is developed based on the conventional one. The motion systems for the linear motion are put on the tilt platform. The motor system consists of a motor, a reducer, an encoder, a lead screw and a linear guide. The reducing ratio of the reducer is chosen to satisfy the requirement of resolution. Among the linear motions, the Y and Z-motion transferred to the holder tip through a spherical joint. Therefore, the Y and Z-motion is reduced with a lever ratio by the spherical joint. The sample holder with the specimen is transferred through a guide column to put the specimen at the center of the vacuum chamber. The sample holder and the linear guide column are designed for an air-lock. Finally, experiments are carried out to show the performance of the developed stage.","PeriodicalId":309525,"journal":{"name":"2019 23rd International Conference on Mechatronics Technology (ICMT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126533690","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}

This work aims at performing a preliminary validation of an innovative device, developed within the SIMeRiON funded project, and identifying the optimal experimental setup for the clinical trials, through the analysis of the characteristics of a planar reaching movement impressed to the upper limb of the subject in a sequence of repetitions. Methods: A male healthy subject (26 years old) has been recruited, and asked to perform an imposed reaching movement with his left arm, during three consecutive sessions. The subject was instrumented with two triaxial accelerometers, placed in two possible configurations, and eight passive optical markers evaluated with a two fixed cameras optoelectronic system. To identify and compare different motion cycles, the collected data have been analyzed in MATLAB and R environment. Results: Data emphasize a high repeatability of the imposed movement, especially at human-machine interface, and suggest that accelerometers data could be integrated with different sensors (e.g. sEMG sensors).","PeriodicalId":309525,"journal":{"name":"2019 23rd International Conference on Mechatronics Technology (ICMT)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123637683","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}
