Adaptive iterative feedback control for nonlinear system with unknown control gain
Abstract：An adaptive iterative feedback control approach was proposed for a class of single-input, single-output uncer-tain nonlinear systems with completely unknown control gain. Unlike the ordinary iterative learning control which required somepreconditions of stability on the learning gain, the adaptive iterative feedback control achieved the convergence through an un-known feedback gain in a Nussbaum-type function. It was proved that the repetitive tracking error sequence was asymptotic tothe interval [ - δ, δ ] for arbitrary prescribed δ＞ 0 when iterations go to infinity. Simulation is carried out to show the validityof the proposed method.
