Iterative learning control design on nonlinear time-delay systems

A robust iterative learning control algorithm is proposed based on T-S model for a kind of nonlinear time-delay systems with repetitive actions. Firstly, the proposed algorithm uses fuzzy T-S model to build the model for nonlinear time-delay system, secondly, the global fuzzy system model could be described as the form of uncertain systems, finally, the robust iterative learning controller is designed through resolving Riccati equation. The sufficient and essential condition of the algorithm is deduced based on Lyapunov theories for nonlinear time-delay system.
