Achieving predictions on contaminant levels has a high impact on quality insurance and it can help technicians and engineers to make adjustments in advance to improve the quality of the final product, and thus profits. In this paper, exploratory research is performed on the problem of silica concentrate estimation for iron ore froth flotation using machine learning techniques, with the goal to identify algorithms that may be suitable for industry soft sensor development. For this purpose, a public, real process dataset is used and three different machine learning techniques are implemented: Random Forest (RF), Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU). The techniques were implemented, tested and compared in terms of their error percentage, mean absolute error, mean square error, and root mean square error. Obtained results show acceptable performance for LTSM and GRU implementations, being LSTM network the out-performer with errors below 9%.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133886237","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, the GOA is applied for solve successfully numerous optimizations problem, it failed to solve other cases efficiently and it prone to stuck in local optima. Thus, an improved version of the GOA is proposed to enhance the performance the conventional GOA. The improved GOA (IGOA) is based on improving the exploration and the exploitation process of the GOA. The exploration is enhanced using a mutation operator to enable the algorithm to a new area to avoid the stagnation of this technique while the exploitation process is enhanced using an adaptive operator to update the positions of the grasshopper around the best so far solution. In this paper, the IGOA is applied to address the allocation problem of renewable energy resources in radial distribution grid (RDG). The renewable resources include hybrid solar wind based Distributed Generator (DG) units for the expected power loss minimization to consider the uncertainty in the electric system. The IGOA is tested on 85-bus distribution grid and the captured results are compared with the traditional GOA to verify its applicability and efficiency. Numerous scenarios are generated using Monte-Carlo simulation to take into consideration the uncertainties of system which include load demands, solar irradiation, and wind speed variations. The simulation results demonstrate that the IGOA is superior for addressing the allocation problem of DG compared with traditional GOA in terms of objective function.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133387387","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 large proportion of adults who survive such an accident can recover; however, this is achieved after going through a long process of kinesiology rehabilitation. In recent times, there are numerous advances in medical equipment, systems and applications that allow a progressive recovery from the consequences caused by this type of accident. The purpose of this work is to analyze the state of the art in which kinesiological rehabilitation technologies are found, through a systematic review of the literature, which also allows to determine the effectiveness of the application of these technologies in the recovery of patients. Motor rehabilitation technologies, based on virtual reality environments and robotic equipment, were identified for adult patients who present hemiparesis or hemiplegia. A great variation was found in the treatments and scales used for its evaluation, in the motor functionality of the upper and lower limb. In the case of robotic technologies, improvements in the range of motion of the limbs, gait and functionality of the upper limbs and muscular endurance stood out. Also, it highlights the adherence of patients to therapies with virtual reality technologies, since these were partly stimulating and enhanced positive aspects such as self-esteem. The work represents a contribution to engineers, who are interested in specializing in patient rehabilitation technologies.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116772969","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 this context, the entire world is looking forward to produce electricity by the means of -mainly- solar and wind energy, but also searching for other clean alternatives. This electricity may be used to transport people into and out of the cities, helping to reduce pollution gases that every day saturates big towns. In fact, it is expected for electromobility to be the most important way to transport people by 2050, and therefore, the design and development of proper control algorithms for electric machines become imperative in order to improve driving and safety in modern powertrains. This paper studies and reviews some of the most important works, with a special mention about, regenerative braking, grip improvement, and vectorial torque control considering the entire car dynamics. As results, this document shows the importance of proper electric powertrain control such as MPC (model predictive control) which helps with critical safety decisions that make the car stable, DTC (direct torque control) which labor is to ensure the right amount of torque is produced by the power unit in order to comply with the decisions made by the MPC or the Fuzzy Logic Controllers. All these control strategies make cars even more flexible, safe and robust than traditional combustion ones.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123529820","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 other ways, the induction motors of most industries are the main component as they consume the highest percentage of energy and this consumption depends on the internal parameters that control the operating conditions of the motor. Despite the success of applying many algorithms to calculate the parameters of induction motors, these algorithms have important defects; they often get suboptimal solutions as a result of an improper balance between exploitation and exploration in their search strategies. This paper applies a demand-based optimization (SDO) as an efficient and simple algorithm for estimating equivalent circuit parameters of induction motors. The variation between the calculated and manufacturer data are minimized as objective functions which considered in the torque (starting torque, maximum torque, and full load torque) and full load power factor. The results indicate that the SDO is superior as it has a less deviation than the results obtained with five recent techniques.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129196976","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}
