Double Star Induction Machine (DSIM) Operation without ADRC-controlled Current and Speed Sensors

Abstract

The present study discussed about an operation of the double start induction machine (DSIM) without current and speed sensors controlled by active disturbance rejection control (ADRC). The main motivation behind this work is to reduce the cost of the installation, simplify the wiring and the operation of maintenance, and increasing reliability. Without current and speed sensors, the machine can be operated in an economical and straightforward manner. The main benefits of this approach are the ability to reconstruct the phases of the stator current and the rotor speed using just one DC voltage. The proposed model uses a technique of estimation and reconstitution of stator current and rotor speed from a single DC voltage sensor. Following the use of two voltages, observers are used to calculate the rotor and stator speeds. Under various simulation scenarios, this method's performance and efficacy are validated in MATLAB/Simulink. The simulation results demonstrate this method's ability to produce results that are on par with DSIM when using current and speed sensors.
