Nonlinear fault tolerant control for polynomial systems with input saturation

This paper studies the optimal fault tolerant control (FTC) problem for polynomial systems with guaranteed cost in the presence of actuator faults. The considered fault is a typical aberration in actuator effectiveness. The novelty lies in an index of the effect of the nonlinear terms which formulate the FTC design problem with input saturation and faults into a semi-definite programming (SDP). A numerical examples is given to verify the applicability of this new approach for the nonlinear FTC synthesis.
