Fuzzy Control of Induction Motor Actuator with Open Loop PID Controller in Water Treatment Plant

Abstract

To solve the problems in the water plant crisis, intelligent control is a highly potent technique. A fuzzy PID controller with auto-tuner capabilities is used to control the actuator in the power plant circuit. The frequency converter's controller is used with an induction motor (IM) as the actuator to stabilize the water flow across a predetermined distance. Simscape/Matlab 2020a was used to simulate the water plant (WP) circuit with the tank station in the water supply system before it was tested over various distances to gauge its current, speed, torque, and voltage. In the present model, four pump stations were used. The pressures were estimated at different distances, i.e., 40 m, 45 m, and 60 m, from the water treatment plant. In the fuzzy logic controller with 7x7 rules, the Mamdani inference engine was used. All electrical parameters were constant, while the pressure validated the system's stability. The findings demonstrated the circuit’s effectiveness and constant pressure within the water treatment circuit.
