The authors have already conducted a research work on a rapier loom servo control weft inserting mechanism.Based on the results of the research work, we have reported that the mechanism is effective in reducing the weft tension and stabilizing the weft insertion.In terms of its control performance, however, this mechanism failed to perform satisfactorily due to the limited control capability of the PI control method used in it.<BR>Accordingly, the authors conducted a further research work on a similar weft inserting mechanism to improve its control performance by incorporating a "Modified Repetitive Control with Corrected Dead Time", which the authors have already proposed as an improved control method, into it as its control system.In the research process, the authors studied the specific method for incorporating the "modified repetitive control with corrected dead time"into the weft inserting mechanism, and investigated its control performance both through simulation and experimentation.<BR>The results of the simulation were in good agreement with those of the experimentation, proving that the control method incorporated into the weft inserting mechanism, although not effective in improving its control performance in its transient-state period immediately after its startup, is highly effective in providing it with excellent control performance during its subsequent steady-state period.With regard to improvements in the control performance of the weft inserting mechanism during its transient-state period, we presented specific measures for such improvements that are considered to be feasible and confirmed their effects through simulation.
