Nonlinear Approach of Actuator Fault Accommodation
In this paper, a method of actuator fault accommodation for a
class of nonlinear systems is proposed. It concerns the problem
of progressive accommodation to actuator failure. This strategy is
based on the optimal nonlinear controller, and its objective to
maintain the system closed loop stability. The authors show the
interest of the proposed method even for a local analysis when a
linear approximation is used. This work focuses on a solution to
ensure stability while accommodating to actuator failure. An
example is given to illustrate this approach.
