Abstract

Abstract: In this work a new type of hybrid PI controller is presented using the Paraconsistent Logic (PL) as the basis for the mathematical and logical treatment of the signals corresponding to the control variables. This control has the conventional actions PI (Proportional and Integral) together with the logical actions structured in the concepts of Paraconsistent Logic. Compared to conventional techniques, this new type of Hybrid PI Controller with Paraconsistent Logic responded well to the various tests performed in the control loop. The tests and the technical validations were done with evidences that prove the efficiency of the paraconsistent concepts. Highlights: Hybrid control with Paraconsistent Logic (PL) is a new logical signals treatment mode. Paraconsistent Logic can apply to PI Control in pressurized vessel meshes. Hybrid PI Paraconsistent Controller is based on non-classical logics. Paraconsistent Logic Algorithm working in level control mesh of pressurized vessels.
