“…For Lipschitz nonlinear descriptor systems with bounded input disturbances, by solving a Lyapunov equation, a robust state-space observer was proposed in (Gao and Ding, 2007). In this paper were presented the approach is developed for nonlinear Lipschitz descriptor systems, where the solvability, causality, asymptotic stability and performance are guaranteed.…”

“…Some works can be mentioned in the FTC field for nonlinear systems. For example, Gao and Ding (2007) took into account actuator faults for nonlinear descriptor systems with Lipschitz nonlinearities. In the work of Ocampo-Martinez et al (2010), a method which requires only fault isolation was proposed for T-S systems.…”

New methodologies for Fault Tolerant Control (FTC) are proposed in order to compensate actuator faults in nonlinear systems. These approaches are based on the representation of the nonlinear system by a Takagi-Sugeno model. Two control laws are proposed requiring simultaneous estimation of the system states and of the occurring actuator faults. The first approach concerns the stabilization problem in the presence of actuator faults. In the second, the system state is forced to track a reference trajectory even in faulty situation. The control performance depends on the estimation quality; indeed, it is important to accurately and rapidly estimate the states and the faults. This task is then performed with an Adaptive Fast State and Fault Observer (AFSFO) for the first case, and a Proportional-Integral Observer (PIO) in the second. Stability conditions are established with Lyapunov theory and expressed in a Linear Matrix Inequality (LMI) formulation to ease the design of FTC. Furthermore, relaxed stability conditions are given with the use of Polya's theorem. Some simulation examples are given in order to illustrate the proposed approaches.

“…Fault diagnosis is also a necessary part of active fault-tolerant control (Blanke et al, 2016). In recent years, significant research effort have been dedicated to fault diagnosis for descriptor systems, such as H − /H ∞ fault detection methods for nonlinear descriptor systems have been studied in López Estrada et al (2015); Boulkroune et al (2013), fault estimation of nonlinear descriptor systems (Koenig, 2005;Gao and Ding, 2007). In an uncertain control system, system disturbances and measurement noise have an important effect on the fault diagnosis result.…”

This paper considers actuator-fault estimation for discrete-time descriptor systems with unknown but bounded system disturbance and measurement noise. A zonotopic fault estimation filter is designed based on the analysis of fault detectability indexes. To ensure estimation accuracy, the filter gain in the zonotopic fault estimation filter is optimized through the zonotope minimization. The designed zonotopic filter not only can estimate fault magnitudes, but it also provides fault estimation results in an interval, i.e. the upper and lower bounds of fault magnitudes. Moreover, the proposed fault estimation filter has a non-singular structure and hence is easy to implement. Finally, simulation results are provided to illustrate the effectiveness of the proposed method.
