Description

These research results concern the concept of applying the Extended Luenberger Observer (ELO) with additional estimation of rotor resistance for the implementation of the current sensor (CS) fault-tolerant control of induction motor drive. Additionally, a modification of the ELO has been implemented to enhance the quality of the stator current estimation, even in the case of a faulty CS. The study investigates the quality of stator current estimation in the absence of faults or in the case of a fault occurring in one of the two CSS. The simulation results confirm the high effectiveness of the proposed solution on a wide range of speed variations.

The data used in this research are attached and contain the transient signals obtained from simulations described as follows:

Description of the file notation:

mea - measured values

real - ideal values (without measurement noise)

emlo - values estimated by the EMLO estimator

c - values used in the control structure and observer, calculated based on measured and estimated values

ref - reference values

IM - values in the induction motor model


H - both sensors intact

A/B - damaged sensor in a given phase

M - motoring operation mode

R - regenerating operation mode

m100 - load torque value [%]

w100 - speed reference value [%]

k180 - wsp k0 = 1.8
