Modelado y control de posición de un cilindro de doble efecto utilizando Pid y Pid-difuso con matlab y labview.

Abstract

This work performs the control of a pneumatic system that performs fast and with great force, with nonlinearities such as friction, dead time and dead zone, using two control strategies, PID-Classic and PID-Diffuse, in order to Analyze the control, performance and error of both controllers. The identification of the system is done with Ident of Matlab using a non-linear identification based on the Hammerstein-Wiener model that is validated by RMSE and the design of the PID-Classic control is done with the help of Sisotool, while the design of the PID- Diffuse is done in the "Fuzzy Logic Designer" of Matlab. On the other hand these controls are implemented in Labview where you can monitor and establish the position of the system in real time. The results obtained in this project are evaluated using the IAE and ISU indexes showing an advantage in the Diffuse control.
