Pbkp_redictive and adaptive nonlinear controller applied to a drying process of cocoa beans

Abstract:

This paper describes the study for the design of a pbkp_redictive controller based on the parametric model obtained for a dryer cocoa plant. The drying system is a nonlinear process, the parametric model obtained is nonlinear, these conditions allowed test the performance of algorithm NEPSAC (extended, pbkp_redictive and self-adaptive nonlinear controller). It shows characteristics of the plant and a brief description of nonlinear model of the plant is made. The controller design details are shown and furthermore NEPSAC results are compared with Generalized Model Pbkp_redictive Control (GPC) and PID control results. The implementation of the controllers was done using MATLAB® Software and an embedded system for the collect of the data.
