The methodology is based on a model of losses of the machine. Based on the model the efficiency at an arbitrary point can be calculated and an error between the calculation and measurement can be determined. The mathematical model is adapted in such a way that the error between the model and experiment is minimized. The model has from 7 to 20 adapted parameters. The search for the optimal parameters is done with two approaches: brute force and Monte Carlo search. The results are compared in the paper. With the Monte Carlo search the algorithm finishes in few minutes, based on the number of parameters. The result is an analytical function for the efficiency map and the efficiency can be calculated at an arbitrary point with arbitrary precision. The resulting fit between the measured and calculated map is within a few percent difference.","PeriodicalId":166043,"journal":{"name":"2020 19th International Conference on Mechatronics - Mechatronika (ME)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116138946","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 order to address these issues, the paper presents the design of an automated handling robot to dispense seeds in the bio-laboratory based on a modified 3D printer frame with an additional axis and sensors. The robot was equipped with additional sensors and functionalities for control and monitoring. Seeds are picked up and dropped accurately by a vacuum tool mounted on the mobile carriage of the robot’s frame. The pick-up process is guided by a seed detector sensor. Moreover, an additional needle length sensor combines with the distance sensor to detect the released distance for an accurate position. In the experiments, we investigate runtimes, the archive accuracy and describe the modular design of the robot to show that the prototype is well sufficient to distribute accurately small seeds to the dish.","PeriodicalId":166043,"journal":{"name":"2020 19th International Conference on Mechatronics - Mechatronika (ME)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117318905","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}

We have prepared a decision network to support the AGVs missions by real-time internal diagnostic to prepare more reliable AGV solutions in smart factories. The internal diagnostics monitors the sensors/inputs signals and internal communication channels to take decision on further actions to perform within the given environment [13].

Moreover, it is important to determine the velocity, acceleration and length of the path. This gives an overview of the basic parameters of the operation and enables preoperative planning. The proposed approach makes it possible to evaluate the technical abilities of the surgeon during the suturing operation in an objective manner by specifying quantitative mechanical values, such as: time of the operation, length of the path, and the speed, which are required to achieve proper performance of the procedure.A system of synchronized motion detectors was used in the form of digital cameras with a CCD matrix. The cardiac surgeon’s movements were recorded at a frequency above 30 Hz. The APAS system was applied for kinematic analysis. Mechanical quantities and phenomena were determined based on FDM and analytical geometry.The results section demonstrates the trajectories of various operational activities. Times of classical, endoscopic operations and the usage of a medical robot were also assigned. The results are presented in spatial charts.Information about the duration of individual operations was received.

The role of BMS (battery management system) is necessary for correct and safe operation of the battery. This task can in principle be categorized into several sub-parts - power interface electronics, monitoring analog front-end (AFE) circuits, communication peripherals and a central control unit equipped with the appropriate software. The battery management system is used for continuous dynamic monitoring of the flow of electricity and is implemented by supporting circuits of the BQ769x0 series. The choice of a specific circuit mainly affects the variable series combination of cells. The single-processor control unit, outside its energy-saving operating phases, reads the operating information from the AFE circuits with the required period, which is processed by the implemented algorithms. The principle of advanced control requires full control over the connected Li-Ion cells, which are initially thoroughly mapped by the first operating cycles. The central control unit must have an options for recording operating data on the MMC, service USB communication and wireless connection via a Bluetooth module for service tasks.","PeriodicalId":166043,"journal":{"name":"2020 19th International Conference on Mechatronics - Mechatronika (ME)","volume":"258 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123097088","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, only the narrow band of G.fast subscriber lines is ready for practical deployment. Due to this fact, simulations and modeling of G.fast lines based on different transmission parameters and environment are important in order to estimate future access networks development. For that reason, it is important to implement additional parameters to provide more accurate and relevant modeling and simulations of real access networks and various types of G.fast transmission lines. This paper deals with modeling and simulations of G.fast lines in typical twisted pairs in industry environment. The article provides calculations and simulations of G.fast lines for various types of metallic cables and under different conditions, including specific profiles of crosstalk spectral densities. Next, these theoretical simulations are compared with real measurements, which increases the accuracy of the modeling. These presented models can be used to accurately estimate the performance of local networks under different conditions in practice.","PeriodicalId":166043,"journal":{"name":"2020 19th International Conference on Mechatronics - Mechatronika (ME)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127664600","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}

As a consequence, resulting control structure based on linear PI controllers is very simple and well tested. However if the back EMF of the machine is not sinusoidal, single coordinated dq system fails to adequately describe the motor, which negatively impacts the control performance and causes additional torque ripple and joule losses in the motor. A commonly used methods for compensation of negative effects of non-sinusoidal back EMF significantly increase the complexity of the algorithm. In this paper we use popular version of predictive control called FCS-MPC which does not relies on the park transform, and thus it allows to address this issue in a simple way. The algorithm has been tested in simulations using the real data of target permanent magnet synchronous motor (PMSM) drive of rated power 100kW.","PeriodicalId":166043,"journal":{"name":"2020 19th International Conference on Mechatronics - Mechatronika (ME)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130385582","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}
