“…For the problem of fault isolation, mathematical method is usually employed to solve the malfunction coefficient, but the method is too complex to achieve (Rezaei et al 2012, Dong et al 2011. Yang (2016) put forward a way to calculate the correlation coefficient between the residual and the fault characteristic signal, then according to the correlation coefficient to isolate fault.…”

Compared with other components, actuator fault has a higher probability of occurrence in semi-active suspension with magneto-rheological (MR) damper, which will lead to the safety and reliability of the system. Hence, the fault diagnosis and fault-tolerant methods of semi-active vehicle suspension system with MR damper are investigated in this paper to deal with the fault of MR damper. Firstly, the quarter-vehicle suspension system model is established. Secondly, an unknown input observer (UIO) with strong robustness and simple structure is employed to detect the fault of MR damper; meanwhile, the correlation coefficient method based on the system residuals is used to isolate the fault of MR damper. Lastly, the skyhook fault-tolerant controller (FTC) is designed to compensate the system with fault application. The simulation results under sine excitation, random excitation and bump excitation show that the performance of the proposed FTC always outweigh that of without fault-tolerant when MR damper occurs fault.

“…FOSM observer for FTC in IMs is proposed in [19]. Similar approaches involving the use of FOSM-based observers for fault detection and control are analysed in [20,21]. In [22], an integral sliding mode (ISM) current controller for the IM is implemented to decouple the d − q currents and compensate the parameter variations in the current loops of the machine.…”

This study proposes a new decoupled control method for induction motor (IM) based on higher order sliding mode (HOSM) controller. The proposed controller serves dual purpose by offering decoupled control and sensor fault detection. In this scheme, the decoupled control of d − q currents does not require the knowledge of the speed. The HOSM controllers play the same role as the compensation voltages produced by a decoupling compensator. From the compensation voltages, the speed can be estimated accurately through algebraic calculations. The estimated and actual speeds are then employed for fault detection algorithm to detect the fault. Simulations on a 1/4-hp three-phase IM in the presence of random measurement noise highlights the performance of the proposed approach for decoupling current control and robust sensor fault detection.
