“…An offset fault means a perturbation caused by the difference between the real speed and its value measured by the sensor. This fault is simulated as shown in figure 5, by injecting a constant value to the real speed, so we can write that follows [10]:…”

This paper deals with a comparative study using numerical simulations between the failures effect caused by the speed sensor faults for a propulsion control system (PCS) of an electrical vehicle (EV) using dualinduction motors structure. The PCS strategies are achieved on two types of controls where the first one is done from a flux-oriented control (FOC) and the second one is conducted from a direct torque control (DTC). For an electric vehicle, we will often guarantee service continuity, in spite of the occurred faults such as an offset fault in speed sensor and a zero-feedback sensor speed fault which both are essentially needed in the structure of the PCS-EV. The occurred fault cited above might influence one of the dual induction motors which could be conducted an unbalance in the dual used motors and from which the control of the vehicle might be also lost. The results of the realized numerical simulations on the EV conducted by the PCS demonstrate clearly the impact of the so-called-fault. Thereafter, we can also appreciate the robustness using each used control propulsion system in despite of the occurred speed sensor fault.

“…Rotor speed sensor is considered as the main important sensor used in the IMD. The accuracy of the signal from this component is crucial, but very sensitive to the current drive and weather conditions [3] which leads to unsatisfactory behavior of the whole system. Consequently, the topology of the system must be changed if the speed sensor is damaged [6,7].…”

The design of electrical drives capable of tolerating sensor faults has recently become very popular due to their possible use in Fault Tolerant Control systems. This paper introduces a virtual speed sensor design based on a nonlinear state estimation algorithm for fault-tolerant vector control for Induction Motor Drives after speed sensor faults. The rotor speed estimator is realized by integrating the Unscented Kalman Filter (UKF) and the Sliding Mode Observer (SMO) based only on the measurements of the stator current and voltage. This proposal is dedicated to maintain the proper behaviour of the Indirect Rotor Field Oriented Control of the induction motor drive, where it is necessary to switch to the nonlinear estimators as a result of damage to the speed encoder. Simulation studies of the proposed fault tolerant design are performed in the case of total and partial losses of the speed sensor in a closed loop control structure for different operating conditions of the drive system. Fault-tolerant designs based on the UKF and the SMO estimators show good performance in the presence of speed sensor faults in terms of stability, overshoot rate (less than 10%), and trajectory tracking over low and medium speed range. However, the SMO performance is reduced for high-speed operation (⍵r >1400rpm) over the UKF which maintain good performance over the entire speed range.
