This paper contains a new alternative to control a pH neutralization process using a PID control with predictive characteristics. The structure uses a Wiener model of a pH simulator that corresponds to a bench-scale plant at University of California, Santa Barbara (UCSB). The study concluded in a new alternative, named WPIDp (Wiener PID predictive) with good performance. We compare the new algorithm...
In the development of this project, the human eye simulation is shown focused on the damages that are caused by the increased intraocular pressure, IOP, as the main cause of Glaucoma and the strong impact it has for being the second cause of blindness in Ecuador. This simulation intended to collaborate with the early detection and diagnosis of that illness. It is used a visual examination database...
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 an alternative technique for the artificial drying of cocoa. The proposal is based on the use of a drying cylindrical and rotating type, the same that uses a flow of hot air to produce the convective heat transfer, in this way is achieved remove moisture contained in the cacao beans. Normally artificial drying systems cocoa, working in batches; this research the feasibility of...
This paper is based on hyper spectral image analysis during organic violet cocoa bean fermentation. The hyper spectral vision has yielded valuable information on evolution during traditional fermentation. It has detected a significant parameter known as the anthocyanin reflectance index 2 (ARI2) of hyper spectral image of two bean regions (cotyledon and pulp) and has been correlated with the pH, temperature...
