Notes:
As a high-performance flexibility coupling, nonlinear grid coupling has been used widelyin many fields, such as aerospace, aviation, metallurgy for instance compressor system and so on.Over a long period of fatigue operation, its structure parameters will change a lot. The system is apt togo chaos, which results in the whole system instability. According to reliability theory and adaptivecontrol theory, an adaptive control model of nonlinear grid coupling is built in this paper, and a novelparametric adaptive algorithm is presented. In addition, combining with an instance some numericalsimulation analyses are performed. The reliability of chaotic system of nonlinear grid coupling iscalculated, and some comparisons with the reliability that in normal state are provided. Calculationand analysis results show that the parametric adaptive control method possesses strong capability ofstability in control, and the working state can be adjusted to normal timely. Consequently, thereliability of controlled system increases remarkably compared with the reliability of chaotic system.The method opens up a new way for reliability design of mechanical system, and provides a way tomonitor the security of the whole system dynamically
