For that, an algorithm was created with all the proposed steps, applying to a Peltier cell and comparing the results with two controllers: gain scheduling adjusted by a classical technique and PI controller adjusted with multiobjective optimization presented in [1]. With the reduced set, two new controllers were created: the first one optimizing a controller for each model in the set separately; the second one optimizing a single controller optimizing the whole set. As a result, it is observed that the separately optimized group is able to control almost as well as the gain scheduling adjusted by a classical technique and the PI controller tuning with multiobjective optimization, but both present a great effort in the control action. With a single controller, the response is slower, but the effort of the control action is significantly better.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"16 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":"127441680","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 work studies the effect of partial shading on a solar array, composed by many panels in series and parallel to achieve a given amount of power to inject energy into the grid. The focus of this work is toward the design and implementation of an algorithm capable to find the global maximum power point despite the existence of other local maximum power points (MPPs). The algorithm is based on scanning for the maximum power point around points of state space, where it should, if the actual power changes as a function of irradiance and temperature. In order to control the voltage at the photovoltaic solar array, a DC-DC boost converter is employed, which is controlled by using the steady state model. Simulated results show the feasibility of the proposal and a fastdynamic behavior associated to finding the maximum power point, no matter where the global MPP is located.","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":"129152792","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, some control problem drawbacks such as process non-linearity, or the non-convexity of the resulting optimization problem generate a higher computational cost for real-time MPC implementation, requiring embedded devices with a higher memory and processing capacity. Consequently, MPC is mostly used in processes with large time constants and/or where devices with high computational performance are available. In this article a controller based on a Neural Network trained from the data generated by a suitable MPC is presented. The proposed controller uses a Recurrent Neural Network to accurately predict the control input based on the previous training data, and once trained the RNN replaces the MPC completely. This reduces the computational cost by not requiring to solve the optimization problem online. The effectiveness of the proposed approach is demonstrated through simulations on a multivariate four coupled-tanks system.","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":"134325477","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 control law has been obtained based on the free and forced responses. Then, the design of independent TITO controls was carried out, using the Simulink/Matlab environment. Likewise, the evaluation of the interactions has been developed by using the relative gain matrix (RGA), to later perform the coupling of the loops with PIDs. Within the study, the behavior in the face of changes in the prediction horizon, changes in the control horizon, and the behavior in the face of changes in lambda and delta weights in the objective function have been analyzed, and additionally, the behavior in the face of disturbances was observed, this to make a comparison between the performance of a PID control (coupled system) and a GPC control. It has been found that the GPC control strategy presents a much better performance concerning the rise time, to the establishment time for the strategy with coupled PIDs. However, the PID still has the advantage of faster tuning due to the tuning tools.","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":"129367705","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}

Great efforts are being made to develop and adapt technologies that make possible to harvest inexhaustible energy sources such as wind, solar, waves, etc. There are different stages associated to renewable energy injection: first one is the energy extraction, this can be implemented with solar panels, turbines, etc.; the second stage considers power conversion, and in the final stage, transformers make possible energy transmission to users. This paper focuses in the design of a suitable control strategy for a power converter to inject energy from solar panels, tracking the maximum power point. In this paper, an optimal control strategy is tested in a Buck-Boost power converter which is capable to vary the voltage at the first stage to follow the inputs and extract the maximum amount of power, in spite of bounded variations in irradiance and temperature. Particularly, a Linear Quadratic Regulator (LQR) is combined with a Kalman Filter (KF) to regulate a Buck-Boost output for the rejection of constant disturbances, thus mitigating measurement noise. Obtained results show that the proposed controller achieves an acceptable performance for the target setting.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"99 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":"128180676","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}
