Abstract
This paper aimed to develop an intelligent controller based on fuzzy systems, with a Mandani inference system and Gaussian pertinence functions (MFs). This project was applied to the pressure control of a simulated supply system in an experimental workbench at LENHS/UFPB (Laboratory of Energy Efficiency and Hydro Sanitary of the Federal University of Paraíba). The controller was developed through the relationships between system outputs and inputs and operator expertise, implemented on the LABVIEW platform through a supervisory and interconnected to the plant via a Texas Instruments SCADA (Supervision Control and Data Acquisition) system. Control is performed under a frequency inverter that varies the rotor speed of a pump. Input data is obtained and monitored using three pressure transducers (PT) and one flow meter installed on the CMB (Motor Pump Sets) discharge line. The results show the effective control of pressure , with maximum overrun and reasonable accommodation time to meet the system hydraulic inertia parameters. In addition, the reduction in electrical consumption is consistent, as indicated by the monitoring of CMB's active power and energy efficiency indicators.
