| Abstract: | In this paper, the R-ILC (Remote-Iterative Learning Control) system, which measurement signal and control signal are transmitted by wireless channel, are considered. The impact to the performance of R-ILC caused by transmission time-delay is explored. By introducing the preset control vector, a transmission time-delay effect compensation method is proposed. The simulation results show the effect of the proposed method. |
