“…The larger offset and scaling error of phase current sensors would bring about the worse performance of torque regulation. Moreover, if the offset and gain drift are above some certain level, it would cause over-current trip at high speed and in heavy load conditions [2]. So it is necessary to consider fault-tolerant operation of phase current sensors.…”

“…A report on the faults of variable speed AC drives [12] shows that 38% of faults are located in power switching devices, 53.1% in control circuits and 7.7% in external auxiliaries. Different sensor faults such as encoder fault, DC-link voltage, and current sensor faults are discussed in [13]. Most common power converter faults are: a single transistor short circuit, a phase-leg short circuit, open-phase, a loss of driving signal, a capacitor short circuit fault, and a two or three phase short circuit [14-Single Open-phase Fault Detection with Fault-Tolerant Control of an Inverter-fed PMSM A.

In this paper first a current predictive method for single open-phase fault detection in a three phase drive with a permanent magnet synchronous machine is presented. The proposed method is based on a predictive stator current calculation. For each sampling interval the difference between the actual stator current and its predicted value in a previous sampling interval is calculated. To identify the location of a single open-phase fault, an identification method is presented which is based on the analysis of the stator current vector angle. After the single open-phase fault is detected and identified it is desirable for the electrical machine to continue operating with a reduced number of phases. For this purpose, a modified direct torque control algorithm for the fault-tolerant control is implemented. In order to improve the performance of the drive, a pre-firing angle is additionally introduced. All proposed methods have been simulated in Matlab/Simulink and verified on an experimental model. Detekcija odspojene faze i na kvarove otporno upravljanje pretvaračem napajanim sinkronim motorom s permanentnim magnetima. Učlanku je prvo predstavljena metoda za detekciju kvara odspojene faze u trofaznom elektromotornom pogonu sa sinkronim motorom s permanentim magnetima zasnovana na predikciji struja statora. U svakom koraku uzorkovanja računa se razlika izmeu trenutne mjerene struje statora i prediktirane vrijednosti iz prethodnog koraka. U svrhu odreivanja lokacije odspojene faze, predstavljena je metoda identifikacije zasnovana na analizi kuta vektora struje statora. Nakon otkrivene i utvrene odspojene faze, poželjno je nastaviti rad električnog stroja sa smanjenim brojem faza. U ovu svrhu implementiran je izmijenjeni algoritam izravnog upravljanja momentom za postizanje na kvarove otpornog upravljanja. Da bi se unaprijedilo vladanje sustava elektromotornog pogona, dodatno je uveden kut prethoenja aktivacije impulsa. Sve predložene metode simulirane su u Matlab/Simulink okruženju i provjerene na eksperimentalnom postavu.Ključne riječi: Sinkroni motor s permanentnim magnetima, na kvarove otporan sustav, kvar jedne odspojene faze, na kvarove otporno upravljanje, kut prethoenja aktivacije impulsa

“…Although, this problem was addressed in the gain margin studies in classical control, the topic has regained attention recently. 21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36 Since more and more implementations of controllers and observers are done digitally, there are numerical round off errors in computation. Also, some implementations need manual tuning with obtaining the preferred performance of the observer system.…”

A class of discrete-time nonlinear system and measurement equations having incrementally conic nonlinearities and finite energy disturbances is considered. A linear matrix inequality based resilient observer design approach is presented to guarantee the satisfaction of a variety of performance criteria ranging from simple estimation error boundedness to dissipativity in the presence of bounded perturbations on the gain. Some simulation examples are included to illustrate the proposed design methodology.
