Differently from other UIOs approaches in the literature, this one focused in using a robust proportional-integral UIO (PI-UIO) with an explicit integrator variable to estimate the states and unknown inputs. First, a discussion concerning the convergence condition for the existence of the PI-UIO is provided. Second, a set of Linear Matrix Inequalities (LMIs) based conditions for H-infinity performance was derived to obtain the observer gain synthesis and minimize the effect of exogenous disturbances in the signals estimations. The effectiveness of the proposed formulation is evaluated through a numerical example, where a proportional UIO and the proposed PI-UIO performances are compared.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"407 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":"134496906","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}

Therefore, reliable approach methods are required to address this issue. This paper analyzes three scenarios generation methods accuracy to represent wind variability. For this purpose, a wind speed database of the Villonaco wind farm located in Loja-Ecuador is analyzed. The wind speed is characterized, and the generation of scenarios is performed through methods based on ARMA models, Monte Carlo, and Moment-Matching techniques. Quality analysis of the scenarios generated is carried out using Weibull probability plots, Kolmogorov-Smirnov Goodness-of-Fit test, and error analysis. It is found that the set of scenarios generated by the Monte Carlo method evidence better performance when both Weibull probability plots and Kolmogorov-Smirnov Goodness-of-Fit test are analyzed. However, set based on the ARMA model exhibit lower Root Mean Squared and Mean Absolute errors. Finally, the wind speed sets are transformed into wind power scenarios considering the power curve and characteristics of the wind turbines.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"11 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":"122322553","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 PBSM was built from analogies between physiology and process engineering, and allows adjusting parameters such as subcutaneous adipose tissue thickness, apparent glucose diffusivity, one-point postprandial blood glucose concentration and its corresponding ISF glucose concentration, maximum glucose uptake rate by adipocytes and glucose concentration at which half the maximum glucose uptake rate is achieved. Also, a comparison and analysis between ISF glucose simulated using two empirically-based models is presented. Previous results achieved using the PBSM model show that physiological delay time between glucose concentration in blood and ISF is in the order of 8-9 minutes, and the current results suggest that interstitial glucose dynamic concentration simulated using the PBSM behaves in accordance with both empirically-based models.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"35 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":"124678011","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 mathematical model to describe glucose dynamic in the blood is developed through five sub-models of the main organs involved in such natural mechanism. In this regard, this paper proposes the integration of the sub-models using as analogy the fieldbus concept in a real chemical plant. In this analogy, the circulatory system is taken as the overall process system and blood as a fluid process entering to each organ and exchanging the glucose, insulin, and glucagon concentrations in blood as the main information. The phenomenological-based semi-physical models were used to describe the roles that each organ performs within the regulation of glucose, insulin, and glucagon in the human body. These organs were modeled as pieces of equipment of a chemical plant. The heart acts as a pump driving the blood, the stomach as a union of pipes of different diameters, the small intestine as a plug flow reactor, the liver is considered as a tank with two immiscible phases, the kidney, pancreas, and other organs as a stirred tank reactor with connections with the circulatory system. On the other hand, the glucose is represented as a process energy, which is consumed or generated by different organs. The integration of the organ models is made in Matlab ®, including 14 sub programs with exit to the circulatory system (concentration of glucose, insulin, and glucagon), one for each organ. Normal values of glucose in blood and some abnormal values representing hyperglycemia were tested in the model. A future work is to improve the code to verify its parameters using real clinical trials.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"53 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":"130359229","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 paper, an adaptive optimal control approach is proposed for primary-secondary control in DC micro-grids under master-slave operation. Stability elimination of voltage deviations is guaranteed, through current control and recursive least squares for identifying the dynamic model. In addition, a linear-quadratic regulator (LQR) with integral action is proposed to improve the stability of the microgrid in a masterslave configuration. Simulation results on a realistic test system demonstrate the advantages of the proposed control.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"25 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":"122630355","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}
