Active flow control for complete elimination of fluid transients. II. Control robustness analysis

摘要

For pt.I, see ibid. p.980-6. The control robustness of an active flow control system using a partitioned optimal flow control system to completely eliminate the nonlinear transient flows is evaluated to assure that such a control scheme can perform satisfactorily when subjected to substantial system uncertainty. The effects of the uncertainties on the control stability as well as accuracy are studied. Recommendations based on the results of the study are made to improve the control robustness of the system.
