However, processing soft materials or products with low quality requirements are getting more interesting for standard industrial robots because of their low investment risks and short delivery periods. On the other hand, disadvantages like low absolute accuracy and low structural stiffness limit the area of industrial applications. Current research activities are focusing on compensation algorithms to reduce the static offset induced by process forces. Thus, this paper presents an approach of a control system which adapts automatically the feed rate depending on the cutting scenario. Linked with a Computer-Aided-Manufacturing system, predefined machining data is analyzed and stored on a separate Edge-Device. This Edge-Device communicates with the machining spindle and monitors the spindle power to monitor the cutting scenario. On this basis, deviations of the milling tool in the areas of entering and leaving the material could be reduced.","PeriodicalId":366332,"journal":{"name":"2019 4th International Conference on Control and Robotics Engineering (ICCRE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127954869","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 multicopter model is represented by kinematics and dynamics of a solid body. The desired position of the multicopter in the formation is determined using the Delaunay triangulation and an optimization procedure. Further the program trajectory is constructed. Then the method of position-trajectory control is used to design the feedback, which provides stabilization of the program trajectory. The results are the thrust and the moments generated by the screws. At the fourth stage, the program trajectory is corrected depending on the current position of the mobile object and the presence of obstacles. As a result of the correction, a singularity occurs in the target position. In order to eliminate the singularity, the problem is solved as a problem of weak terminal control. The analysis of the closed system is carried out.

In the proposed BBACE algorithm, the Cross-Entropy method is embedded in Bat Algorithm to make good balance between exploitation and exploration based on co-evolution. The performance of the proposed method is evaluated on 10 standard benchmark datasets from UCI repository and compared with some well-known wrapper feature selection techniques such as GA, PSO, and ALO.

Surface-hardness (SH) prediction plays an important role in assessing the quality of the surface-hardened steel. In this paper, an intelligent method for automatic SH prediction model establishment is proposed. The proposed intelligent approach involves three key steps. Firstly, hysteresis loops (HLs) are measured from the prepared surface-hardened steel rods with different SHs by a sensor. Secondly, a binary particle swarm optimization (BPSO) feature selection is applied to automatically select optimal feature subset from the measured HLs signal. Finally, a single-layer feedforward neural network (FNN) model is utilized to bridge the relationship between the selected features and SH. The experimental results show that the intelligent method can automatically establish SH prediction model. The optimal feature subset based single-layer FNN model can accurately predict SHs in surface-hardened steel rods with a prediction error of 0.298 %, indicating that the intelligent method can be integrated in an industrial robot for SH prediction in surface-hardened steel rod.","PeriodicalId":366332,"journal":{"name":"2019 4th International Conference on Control and Robotics Engineering (ICCRE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121403261","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}
