Abstract

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.
