The wind turbine is modeled by a two-mass model that deals with wind turbine nonlinear aerodynamics and its flexible models. The controllers aim to maximize the captured energy from the wind whilst reducing the load level of the drive train. Initially, some of the conventional controllers such as sliding mode and integral sliding mode controllers are considered. Nonetheless, these controllers introduce more transient loads. To overcome these issues, a synergetic and terminal synergetic with integral based macro variable are proposed for a two-mass model wind turbine. These proposed controllers are verified through simulation and Fatigue, aerodynamics, structures, and turbulence 600kW model. The simulation results affirm that the terminal synergetic-based integral controller improves transient load reduction than other controllers.","PeriodicalId":340976,"journal":{"name":"2021 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128332574","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 task is not always simple for those in charge of planning and production control, since the main challenge they face is adapting the plans to the particular situation of each company. In this paper is presented the design of a production planning system for a production line of a paint industry, with a simple and effective model for forecasting sales and managing inventories, in order to adequately meet the expected demand but with reduced inventory levels. The results obtained through the validation of the production planning and control system designed in this study show an increase in annual turnover and savings in inventory maintenance costs. These optimizations also imply a significant reduction in sales losses due to stock breaks, loss of materials due to packaging waste, and costs of reprocessing products due to obsolescence and other damages caused by excess storage. Finally, an additional contribution that results from this production plan is the obtaining of the total bill of materials for the manufacture of the products, facilitating the management of the company’s purchases.","PeriodicalId":340976,"journal":{"name":"2021 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"429 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126089266","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 least favourable financing scenario turns out to be the one that users employ only their own resources.

The proposed methodology divides the analysis into three cases, which determine the selection of the number of panels according to (1) supplying of the total demand in the month with the highest solar irradiation, (2) supplying of the total demand in the month with the lowest solar irradiation, and (3) supplying the total demand without having energy excesses injected into the grid, but only produce for self-supplying.
