Última Electrically driven fertilizer applicator controlled by fuzzy logic REA Garcia,Angel P.; Cappelli,Nelson L.; Umezu,Claudio K.. The present study shows the development, simulation and actual implementation of a closed-loop controller based on fuzzy logic that is able to regulate and standardize the mass flow of a helical fertilizer applicator. The control algorithm was developed using MATLAB's Fuzzy Logic Toolbox. Both open and closed-loop simulations of the controller were performed in MATLAB's Simulink environment. The instantaneous deviation of the mass flow from the set point (SP), its derivative, the equipment´s translation velocity and acceleration were all used as input signals for the controller, whereas the voltage of the applicator's DC electric motor (DCEM) was driven by the controller as output signal. Calibration and validation of the rules and membership functions of... Tipo: Info:eu-repo/semantics/article Palavras-chave: Fertilizer applicator; Agricultural machinery; Closed-loop control.
