Abstract :
This paper presents a P-type iterative learning control (ILC) scheme for a class of fractional-order nonlinear time-delay systems with fractional order α (0 ≤ α <; 1). By introducing the λ-norm and using a generalized Gronwall inequality, the sufficient conditions for the convergence of the control input and the tracking errors for open-loop and closed-loop P-type ILC are obtained, respectively. The validity of the methods are verified by a numerical example.
