Adaptive Speed Control of Field-Oriented Controlled Induction Motor Driven Centrifugal Pump Powered by Hybrid Energy Storage System

Abstract

This research investigates the development and application of an adaptive speed control approach for a Hybrid Energy Storage System (HESS)-powered Field-Oriented Controlled (FOC) induction motor. The HESS offers a reliable and adequate power supply solution for water extraction applications by combining a photovoltaic (PV) system, a battery, and a supercapacitor. A single-ended primary-inductor converter (SEPIC) using the Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT) method extracts the most power from the PV system. A PI controller controls the HESS, which consists of a battery and supercapacitor, to maximize energy efficiency and system stability. An adaptive PI speed controller regulates the FOC induction motor with a centrifugal pump to achieve exact speed and torque monitoring. The controller dynamically modifies its gains to adapt to changing operating conditions and guarantee peak performance and energy efficiency. The simulation results show the effectiveness of the suggested system. The FOC permits precise speed and torque control, the SEPIC converter sustains a steady output voltage, and the P&O MPPT algorithm effectively tracks the maximum power point. By increasing the system's reactivity and resilience, the adaptive PI speed controller raises the effectiveness of water extraction. This study advances water extraction technologies driven by renewable energy, fostering effective and sustainable water management.
