“…With the increasing complexity of modern industrial systems and higher pursuit of system performance, fault diagnosis is an important and challenging problem in many practical systems, such as chemical en-gineering, nuclear engineering and aerospace engineering [9,12]. Faults may occur at any time, and then destroy the system stability or even make the system tend to collapse.…”

This paper investigates the problems of fault detection and diagnosis in a class of discrete-time switched systems with unknown state delay against component faults. The component fault, also called the multiplicative fault or loss of actuator effectiveness, is a common type of operation fault for switched systems, which has been paid more attention. In this paper, the learning observers (LOs) technology are proposed to reconstruct both the system state and component faults. The proposed LOs technique is also extended to the system with unknown time delay and external disturbance. The sufficient conditions for the convergence of the output of LOs and the uniformly ultimately boundedness of the reconstructed errors are proved by the switched Lyapunov function and H ∞ technique. The proposed fault reconstruction strategy has certain tolerance for fault types, which is effective for both slow and fast time-varying faults by adjusting the iteration step size. In the simulation parts, three kinds of fault signals are taken into consideration to verify the effectiveness and robustness of the proposed method.

“…In this paper, we extend the proposed technique in ([24]- [27]) for actuator FDI and FE based on only input/output data. The general principle of this fault diagnosis method is to project an input matrix (a matrix that is constructed using input measurements collected in a time window T) on the orthogonal of an output matrix (a matrix that is constructed using output data collected in the same time window T).…”

This paper treats the Fault Estimation (FE) problem using a data-projection method. An on-line fast fault estimation procedure is proposed using input-output data collected on-line and off-line. The model structure of the system (linear, bilinear, ..) is supposed to be known but the model parameters values are not needed. No prior model parameter estimation procedure is required. The method was presented in previous work by the authors for sensor FE. This paper extends the procedure for actuator faults. Simulation results of a separately excited DC motor are presented to illustrate the efficiency of the proposed data-projection method for actuator fault detection and estimation.

Sensor Fault Tolerant Control for Hybrid Systems With Sinusoidal Disturbance

2022

This paper aims to design of an active fault-tolerant control AFTC of switched systems in the presence of sensor fault and periodic disturbances. AFTC requires sensor fault estimation. Thus, a databased projection approach is proposed based on performance measures that allow fault estimation without relying on mathematical models and fault assumptions. A new switching control strategy is proposed for fault compensation and recovering the desired performances. These techniques integrate a bank of controllers, corresponding to a set of partial models to design a set of switching control laws, compensating for the fault effect and attenuating the disturbance. A new linear matrix inequality based on Lyapunov stability analysis is proposed to compute control gains. This technique allows finding the optimal values of the control gains matrices, which ensure both sensor fault compensation and disturbance attenuation. A comparative study of the proposed strategy with existing work is carried out to show the effectiveness of the designed fault-tolerant control.
