LARA-ROJO, F.; SANCHEZ, E. N.  y  ZALDIVAR-NAVARRO, D.. Minimal fuzzy microcontroller implementation for didactic applications. J. appl. res. technol [online]. 2003, vol.1, n.2, pp.137-147. ISSN 2448-6736.

Fuzzy techniques have been successfully used in control in several fields, and engineers and researchers are today considering fuzzy logic algorithms in order to implement intelligent functions in embedded systems. We have started to develop a set of teaching tools to support our courses on intelligent control. Low cost implementations of didactic systems are particularly important in developing countries. In this paper we present the implementation of a minimal PD fuzzy four-rule algorithm in a low-cost 8-bit microcontroller, using a fuzzy logic software development system. On this ground we constructed a stand-alone fuzzy controller for a didactic liquid level system. We describe the methodology we followed, and present simulation and real time results of this controller.

Palabras llave : Fuzzy control; level control; didactic workbench; minimal rule number; real-time implementation.
