Sensorless Field Oriented SMCC Based Integral Sliding Mode for Solar PV Based Induction Motor Drive for Water Pumping

Also Available Domains AC Drives

Project Code :TEPGPS373


The main objective of this project is to regulate DC link voltage, motor power and speed of the motor.


This project focuses on an efficient and robust speed sensorless control for a solar water pumping system consisting of solar Photovoltaic (PV) array fed Submersible Induction Motor Drive (SIMD). The speed estimation and sensorless control of SIMD are quite demanding tasks. Additionally, the motor parameter variations lead to deteriorate sensorless control. Therefore, a sensorless control of Submersible Induction Motor (SIM) requires accurate and robust stator current control. The sliding mode based DC link voltage regulator is adopted for regulating the motor power and the speed for single stage solar PV topology. 

The Integral Sliding Mode Observer (ISMO) based speed estimation of SIM and Sliding Mode Current Control (SMCC) for decoupling of current, provide a robust control against motor parameters variation. The proportional integral (PI) controller based speed sensorless control is used and its performance is verified with a developed sliding mode based control for motor parameter variation. 

The ISM based sensorless control with SMCC for submersible motor serves several benefits in water pumping for agricultural purposes in presence of uncertainties. It gives fast response during dynamics. The precise estimation of rotor speed is achieved for wider range of speed under various dynamic conditions. The developed system with a single stage PV topology and three-phase voltage source inverter (VSI) fed IMD feeding a pump as a load, is designed and implemented in MATLAB/Simulink.
