摘 要:This paper proposes a new adaptive iterative learning control approach for a class of nonlinearly parameterized systems with unknown time-varying delay and unknown control *** employing the parameter separation technique and signal replacement mechanism,the approach can overcome unknown time-varying parameters and unknown time-varying delay of the nonlinear *** incorporating a Nussbaum-type function,the proposed approach can deal with the unknown control direction of the nonlinear *** on a Lyapunov-Krasovskii-like composite energy function,the convergence of tracking error sequence is achieved in the iteration ***,two simulation examples are provided to illustrate the feasibility of the proposed control method.
