Desarrollo de un controlador genético difuso para el módulo de nivel del Laboratorio de Teoría de Control de la UPS

Abstract

The liquid level control module belongs to the control theory laboratory of the Salesian Polytechnic University, which is used to train students in the explanation and orientation of control techniques. In the present project, the module was optimized in both software and hardware, testing the implementation of a new control algorithm called Diffuse Genetics and installing a new level sensor and a new HMI screen to control it, respectively. He began to carry out a characterization of the level module to detect its dynamics and verify its operation. The best control architecture was proposed and planned taking into account the elements present in the existing loop. The design of the new diffuse controller was made based on a multiple input and single output system (MISO from its initials in English Multiple inputs Single output). The optimal control strategy that will interact between the diffuse and genetic algorithms in parallel was proposed. At the same time, the cost function (or fitness function) is established that evaluates the best fuzzy membership function sets that the control will use. Finally, the new Diffuse Genetic Controller will be implemented in the control of the plant level, perform performance tests and statistically validate using performance indices.
