The energy recovery system is built with a pump working as a turbine (PAT), an asynchronous generator, and a four-quadrants converter that connects the system to the electrical network. This system regulates the water pressure at the output of the PAT and, because of the drop in pressure, it injects the recovered energy in the electrical grid. Furthermore, a controller is designed for the system shaping the dynamic response of the system using a Bessel polynomial and practical considerations. The design of the controller is validated through simulations.","PeriodicalId":127488,"journal":{"name":"2020 Argentine Conference on Automatic Control (AADECA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131720530","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 work, two two-level optimization methods are studied, one case considering technical requirements and another considering economic criteria. In the upper level, the supplier optimizes it objective function. Meanwhile, at the lower level, users optimize their electrical costs. The proposed methods are based on Genetic Algorithm (GA) methods. In this sense, an indirect control is established in which users react to a price signal. Simulation results illustrate that both cases improve the demand profile and increase the retailer profit with respect to an unscheduled case. However, when the supplier tries to maximize the profit, some users receive benefits in detriment of others, concluding that the technical approach is preferable to the economic one.","PeriodicalId":127488,"journal":{"name":"2020 Argentine Conference on Automatic Control (AADECA)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122400787","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}

By modeling such behaviour, it is possible to describe and simulate physiological events accurately. The model is applied to describe the movement of chyme, also called gastric mass, through the small intestine, using Fung model to characterize the intestinal walls. The analogy with elastic tanks makes it possible to reliably calculate transit time, and with the addition of digestion and absorption kinetics, the model would be useful to estimate the rate of appearance of substances (e.g. glucose, drugs) into the bloodstream after oral ingestion. The model is phenomenological-based, which makes it possible and simple to adapt it to other particular situations, and even different organs with similar elastic characteristics. Its phenomenological nature also implies parameter interpretability, property specially useful in physiological models.","PeriodicalId":127488,"journal":{"name":"2020 Argentine Conference on Automatic Control (AADECA)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126491898","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, these bioprocesses still pose difficult challenges, due to the nonlinearity and uncertainties of microalgal dynamics. This paper addresses the problem of biomass regulation in a continuous culture of the microalga Dunaliella tertiolecta. Our strategy is based on a Proportional-Integral (PI) controller assisted by a Generalized Proportional Integral (GPI) observer, in order to mitigate the impact of disturbances on biomass levels. The proposed design was tested via numerical simulation, using MATLAB/Simulink™ 2020a environment. The robustness of the controller was demonstrated by subjecting the simulated bioreactor to disturbances and changes in reference biomass densities. The proposed strategy effectively tracked the reference within an insignificant deviation ±0.5%. Furthermore, our proposal effectively rejected disturbances that classical PI was unable to counter.","PeriodicalId":127488,"journal":{"name":"2020 Argentine Conference on Automatic Control (AADECA)","volume":"18 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130929674","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}

Some of these new functionalities have special relevance in the electrical networks of developing countries which present complex challenges and need to be updated fast.

This situation calls for maximizing the efficiency of these types of processes, as well as reducing the contaminants produced. Extremum seeking control (ESC) has the potential to achieve the efficiency required. Here we identify a ladle furnace process using optical variables (OV). We test the options of a Hammerstein or Hammerstein-Wiener plant structures. We then propose an ESC design for the identified nonlinear plant model and simulate its operation. Finally, motivated by a future implementation of the designed ESC over a network, we analyze through simulations three communication networks features: the variance of a communication channel additive noise, the variance of a communication channel gain, and the probability of packet-dropouts.","PeriodicalId":127488,"journal":{"name":"2020 Argentine Conference on Automatic Control (AADECA)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121208323","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 propulsion system consists of an electric motor and the energy storage system is composed of batteries and supercapacitors. The electric vehicle is a power system in which the motor and the storage devices are coupled to a common DC bus through power converters. A proper energy management of the energy storage system is required to meet the power required by the electric motor. Since the storage devices possess complementary electric characteristics, it is expected that the controller achieves the main task of satisfying the demanded energy, exploiting these features to get substantial benefits in the vehicle driving performance and the battery life. In this article, we propose an energy management designed via passivity-based control for a battery/supercapacitor electric vehicle. The controller commands the energy storage system to satisfy the electric motor demand, reducing the high peak power undergone by the battery through the high power capacity of the supercapacitors. The methodology is tested under several demanding driving cycles and the results show that the battery life could be significantly extended.","PeriodicalId":127488,"journal":{"name":"2020 Argentine Conference on Automatic Control (AADECA)","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124494942","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}
