Operating of DSIM without Current and Speed Sensors Controlled by ADRC Control

Abstract

This paper presents an operation of the double start induction machine (DSIM) without current and speed sensors controlled by active disturbance rejection control (ADRC). The operation of the machine, without current and speed sensors, is an economic and simple method. The main advantages of this method are the reconstruction of stator current phases and rotor speed using only one DC voltage. The method is very simple and effective. It is based on the information provided by a DC voltage and the switching states of the converters to reconstruct the stator voltages. After we use two voltages observers to estimate the current stator and the rotor speed. The performance and the effectiveness of this method are verified under different conditions of simulations in MATLAB/Simulink. The results of the simulation prove the ability of this method to produce the same performances of DSIM with the current and speed sensors.

Optimal Fractional Order Proportional Integral Controller for Dual Star Induction Motor Based on Particle Swarm Optimization Algorithm

“…However, the constraints on the power components limit the switching frequency and, thus, the performance. Therefore, the power must be segmented to enable the use of components with higher switching frequencies [1][2][3]. One way to ensure this is to use large phase (or multi-phase) machines, and as an example of this type is the dual star induction motor.…”

Enhanced Control of Dual Star Induction Motor via Super Twisting Algorithm: A Comparative Analysis with Classical PI Controllers

“…Although the three-phase asynchronous machines are the mainstream in application, the multi-phase machines, especially DSIMs, are now a compelling alternative for high-power systems [4,5]. DSIM has two windings with https://doi.org/10.56578/jisc020404 isolated neutrals, spatially phase-displaced by α = 30 electrical degrees [6,7]. To realize variable speed drive for DSIM, two PWM voltage sources, controlled by the IFOC strategy, are used to supply these windings.…”
