Robust reconfigurable control for parametric and additive faults with FDI uncertainties

From the system recoverability point of view, the paper discusses robust reconfigurable control synthesis for LTI systems and a class of nonlinear control systems with parametric and additive faults as well as derivations generated by FDI algorithms. By following the model-matching strategy, an augmented optimal control problem is constructed based on the considered faulty and fictitious nominal systems, such that the robust control design techniques, such as H/sub /spl infin// control and /spl mu/ synthesis, can be employed for the reconfigurable control design.
