| 英文摘要 |
| A two-layered operational control model is firstly established for the optimal operational control for industrial
processes. Based upon such a new model, an integrated fault tolerant control for the operational control layer is obtained
using the adaptive fault diagnosis scheme. The proposed method adjusts the optimized set points so as to achieve the
original optimal operational control effect when the system is subjected to either faults or disturbances. Detailed analysis
has been made on the construction of the adaptive diagnostic algorithm for fault diagnosis using of Lyapunov stability
theory. It has been shown, by tuning the optimized set points to the loop control layer, that the proposed method can ensure
that the operational control can converge to the original optimized control effect when there are faults in the loop control
layer. Indeed, the proposed method is in fact an incompact fault tolerant control scheme, where the simulation studies have
shown its effectiveness. |
