Robust control for incremental quadratic constrained nonlinear time-delay systems subject to actuator saturation

作者：

Highlights：

• This paper propose the IQC nonlinear function with time delay for the first time and the nonlinear term is dealt with by the S-procedure.

• The saturated feedback law is constructed and the considered systems are proved to be exponentially stable under the given conditions.

• An optimization problem of maximizing the estimation of DA is derived by CHLF approach, and two simulations are provided to show that the proposed method can provide a larger estimation of DA than the QLF method.
