This paper discusses an approach to robust control law design for fault-tolerant systems. Based on the assumption that the effects of faults can be expressed in Linear-Fractional-Transformation (LFT) forms, a fault-tolerant control systems design problem is formulated and solved via a linear matrix inequality (LMI)-based synthesis approach, to recover the convexity of the design problem whilst considering...
In this paper, we consider the fault accommodation for a class of linear time invariant (LTI) systems with an innovation form. The considered faults are mainly sensor and actuator faults. In the first place, the underlying faults are parameterized such that they can be estimated using the input-output data. If the system is time invariant, the actuator and sensor fault magnitudes can be identified...
A fault-tolerant control strategy based on a robust model-based approach is addressed in order to design and implement a supervisory system. The approach considers the application of a robust control technique to integrate the control design and the fault diagnosis in the same framework. A model-based approach is used to estimate the system's state variables and to synthesize the robust controller...
