This paper proposes an algorithm for fault tolerance of three-phase, inverter-fed, speed-sensor-less control of a three-phase induction motor drive system. The fault tolerance of the inverter when one switch is open or one leg of six-switch inverter is lost is considered. The control of the drive system is based on indirect rotor field-oriented control theory. Also, the speed estimator is based on model reference adaptive system (using stator current and rotor flux as state variables for estimating the speed). The fault-tolerant algorithm is able to adaptively change over from a six-switch inverter to a four-switch inverter topology when a fault occurs; also, it makes a smooth transition of the motor speed, torque, and current when changing over from a faulty condition to a new healthy status, which is four-switch three-phase inverter (FSTPI) topology; thus, the six-switch three-phase inverter (SSTPI) topology (pre-fault status) is almost retained for the medium-power range of induction motor applications. The proposed algorithm is simulated by using the MATLAB/SIMULINK package. Also, the proposed control system is tested experimentally using a digital signal processor (DSP1104). The obtained results from the simulation model and experimental system demonstrate the performance enhancement and good validity of the fault-tolerance control for the speed-sensor-less induction motor drive system. IntorductionThree-phase induction motors have been the workhorse for industrial and manufacturing processes. A high harmonic current content causes torque ripple on the load when variablespeed induction motor drives operate with an open-circuit phase fault. These effects result from the unbalanced nature of the faulted machine. Different diagnosis techniques for transistor opencircuit faults have been developed and analyzed [1][2][3]. A detection method that identifies the power switch in which the fault has occurred based on measurement of motor voltages is presented in Ref. [4]. It also investigates fault compensation via topologies that are able to maintain the system operation for a period. In Ref.[5], a modeling method for induction motor drives is proposed that includes machine saturation and space harmonics effects as well as inverter nonlinearity, which does not require significant computation times. Also, a descriptionon how the model was used to develop a fault ride-through control strategy for a voltage-fed vector-controlled drive is given. In Ref.[6], the effect of measurement failure error due to faulty sensors and power inverter malfunctions was investigated. Both software and hardware redundancies have been investigated during the occurrence of a failure. Software redundancy has been evaluated in the case of a speedsensor failure. In Ref.[7], a fault occurring when open-circuit winding faults appear on the induction motor drive is considered. A feed-forward compensation term is introduced into the a Correspondence to: Z. M.

“…Similarly, it works as a three-phase machine when adjacent double phase open circuit faults (A2-Ph) occur. These faulty conditions generate torque oscillations due to unbalanced rotating MMF present in the air gap [21]. Connecting a load neutral point to the DC link midpoint reduces the negative sequence MMF component in the air gap and the oscillation without any additional control strategy.…”

Abstract:The developed torque with minimum oscillations is one of the difficulties faced when designing drive systems. High ripple torque contents result in fluctuations and acoustic noise that impact the life of a drive system. A multiphase machine can offer a better alternative to a conventional three-phase machine in faulty situations by reducing the number of interruptions in industrial operation. This paper proposes a unique fault-tolerant control strategy for a five-phase induction motor. The paper considers a variable-voltage, variable-frequency control five-phase induction motor in one-and two-phase open circuit faults. The four-phase and three-phase operation modes for these faults are utilized with a modified voltage reference signal. The suggested remedial strategy is the method for compensating a faulty open phase of the machine through a modified reference signal. A modified voltage reference signal can be efficiently executed by a carrier-based pulse width modulation (PWM) system. A test bench for the execution of the fault-tolerant control strategy of the motor drive system is presented in detail along with the experimental results.

The short circuit is a severe fault that occurs in the stator windings. Therefore, it is very important to diagnose this type of failure in its beginning before it causes unscheduled stop and the machine loss. In this context, the Support Vector Machine (SVM) is a tool of considerable importance for standard classification. From some training data, it can diagnose whether or not there is a short circuit beginning, and which is important for predictive maintenance. This work proposes a technique for early detection of a short circuit between the turns aiming at its implementation in a real plant. The paper shows simulation and experimental results, and validates the proposed technique.
