It is shown that both process gain and integral time change along the operation range, due to non-linear behavior of the process. In current gain scheduling applications, the gain and integral time commutation is abrupt, producing internal disturbances to the closed loop. The issue of these variations and their implication on the controller performance is discussed and solved. Fuzzy modeling is used here as an useful tool for solving the commutation problem. Simulation studies and experimental data show satisfactorily how the proposed algorithm improves the performance of the controller over a large operation range.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"20 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":"127784833","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 microinverter is formed by a flyback converter with active-clamp, a voltage multiplier circuit, and a dual-buck inverter. The active clamp recycles the energy stored in the leakage inductance of the transformer and reduces the voltage stress in the MOSFET. The voltage multiplier helps to reach the DC voltage level required by the dual-buck inverter to inject current to the grid. This paper provides a description of the microinverter’s hardware as well as the calculations used by the flyback and dual-buck controllers, which can be implemented in different simulation software. Experimental results show the capacity of the computational model to reproduce the electrical behavior of the microinverter operating in maximum power point tracking mode and injecting power to the grid.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"20 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":"121700632","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 model of the CPL corresponds to a hyperbolic constraint that introduces nonlinearities on the dynamical model. To regulate the voltage profile in this nonlinear load a passivity-based control (PBC) approach is proposed. The main advantage of the proposed control approach corresponds to the parametric independence of the controller, even if the CPL and the asymptotic stability in the sense of Lyapunov are unknown. Numerical results validate the proposed control approach in comparison to conventional PID controller.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"1 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":"131377666","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 process uses a particularly design tool that rotates and travels along the join, using equipment similar to a milling machine. Control in friction stir welding helps to assure weld soundness if done correctly. Different control approaches have been developed using force, torque and temperature sensors as input variables. Depending on the application this control strategies are successful while using dedicated FSW equipment, looking into local implementation it is more viable and cost effective to employ an adapted milling machine for the job. This type of mechanism only allows setting parameters such as travel speed, rotational speed and depth of penetration, which can be insufficient to obtain sound welds. Based on the set outcome of local implementation model-based control is an alternative to classic control and it uses a set of equations that describe the process as the input. The proposed model consists of a set of algebraic balance equations describing how mass and energy, in terms of power consumption, transform along the process predicting the soundness of the joint in every step. This model serves as the base for a control system that can predict the soundness in the next step and react accordingly, modifying basic process parameters such as plunge depth as well as travel and rotational speed minimizing mass loss. Experimental data has been compared to the model output in order to validate it.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"14 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":"130351775","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 grey-box model combines a formal structure of the phenomenon with a data-driven, generic model. The model is fitted to data until a complete and precise representation is achieved. In this paper, a grey-model based plant identification is carried out to estimate the parameters of a Pittman GM9413-3 DC motor, about which little of information is available. It is the main source of locomotion of the SCORBOT-ER V plus robot manipulator. With the parametric identification of the DC motor, it is possible to approximate the dynamics of the manipulator. The mathematical model is partially obtained by fitting the values of the internal resistance and inductance of the stator, using a linear regression of the data obtained from the DC test and rotor blocked test, respectively, and assuming that no losses are present due to electromagnetic conversion. The data were acquired using an FPGA-based data acquisition system tailored for the application. Results show that the model is precise, with a fitness higher than 84% and a final prediction error of less than 1%.","PeriodicalId":184764,"journal":{"name":"2019 IEEE 4th Colombian Conference on Automatic Control (CCAC)","volume":"1 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":"130486990","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}
