It saturates the system actuators, letting the system out of control with a higher controller action. Putting a saturator for the controller action, it is limited into a linear range of operating values. However, it does not eliminate the cumulative error of the integral term. This paper presents the speed control of a motor generator system using a digital PID controller with antiwindup method to eliminate the cumulative error of the integral term of controller action. Initially, a linear model of the motor generator system was identified. From the linear model of the system, a PID controller was designed using pole placement technique. Controller discrete implementation was performed using the backward difference discretization methodology. PID controller consider the antiwindup scheme and its practical implementation employing the Matlab Stateflow toolbox and a data acquisition card. Obtained results showed that the PID controller with antiwindup digital implementation has a good performance against external disturbances and random noise.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"8 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":"133562848","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 microgrid is a typical cyber-physical system that uses different sources of power generation for supply to a specific population. The adequate coordination on each one of the implemented control schemes allows an adequate functioning of the system. However, this type of system is susceptible to malicious attacks, that affect the performance and operation of the system. This paper addresses the detection and isolation of attacks that affect communication channels with the failed transmission of sensor data and/or controllers. The method of detection and isolation of faults is used, to identify the origin of the attack and provide an intuitive idea of the type of attack that is affecting the system.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"2 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":"128203423","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 leader-follower topology is implemented in a team of 6 mobile robots, which allows that only one robot has the ability to perform autonomous navigation and the rest of them to be guided by this robot. In addition, a method of positioning for agents is proposed, which does not depend on elements external to the system. Finally, the results obtained are analyzed to determine the feasibility of implementing event-triggered coordination and the cases in which this can be performed.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"142 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":"128601971","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 use a suitable degree of simplifications of the MMC converters, under given conditions, to allow system level studies over potentially large networks. The analysis is based on a recently proposed simplified model of the MMC. Based on this model, we propose an analysis using the theory of Contraction to define some stability conditions.

Since some Fusarium species may carry health risks to humans, as well as animal and vegetal species, there is a great interest for detecting them in a reliable way. That is why this paper describes an implementation based both on digital image processing techniques, and artificial neural networks, for identification of some Fusarium species, starting from a microscopic sample image.

This work presents a phenomenological-based semi-physical model (PBSM) to describe the role of the small intestine in glucose homeostasis in the human body. The small intestine is modeled as a plug-flow reactor with three process systems (PS), intestinal lumen, enterocytes, and bloodstream. At every PS, mass balances are performed over the main involved species. Then, the equations with relevant information to answer the model question are selected. Model parameters for an average person were adjusted using experimental data retrieved from the literature. The results show the dynamic evolution of macronutrients degradation in the small intestine, as well as the absorption of glucose, fatty acids, and amino acids into the bloodstream. Moreover, this model provides the dynamic behavior of the enzymatic activity and water, as food passes through the small intestine. Finally, the glucose appearance in the bloodstream is reported. The characteristics of the proposed model allow a reliable representation of the physiology of digestion and absorption of nutrients in the small intestine, for this reason, it can be used in the construction of an artificial pancreas.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"19 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":"124087237","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}
