The following article presents the modeling and control of a refrigeration system for fruit preservation. The mathematical model developed is based on mass balance and energy balance. It has been developed in two blocks: analysis in the refrigeration components and analysis in the conservation chamber. In the refrigeration system the elements have been studied: compressor, condenser, expansion valve,...
This paper presents the modeling, simulation of a double-stage evaporation process to obtain Bioethanol from sugarcane juice; the model was validated with data from a plant located in Peru. So is the calculation of a Nonlinear Control and optimization following the Extended Prediction Self-Adaptive Control approach, because it has less computational load. The results achieved the control of juice...
This paper presents the applications of a Nonlinear Model Predictive Controller (NMPC), this nonlinear controller uses the Nonlinear Extended Prediction Self-Adaptive Controller (NEPSAC), furthermore uses the Generalized Model Predictive Control (GPC) and PID to the control of a Dryer Plant of Cocoa Beans. It shows characteristics of the plant, and it realized the identification for know their dynamic...
This paper presents the dynamic modeling and control of a rotary disc dryer used in fishing industry. The nonlinear model obtained from energy and mass balances, is validated with real data measured in two plants of fishmeal located in the north of Perú. A constrained nonlinear predictive controller is designed with the purpose of regulating the moisture content in the fishmeal to obtain a stable...
Production of biofuel has a positive environmental and economic impact; therefore, the interest for accurate modeling and more advanced control techniques has grown considerably over the last years. The reason is that it allows optimizing the productivity while the energy consumption is minimized. This paper presents the modeling, simulation and nonlinear control of a double-effect evaporation process...
