H-Infinity Control for T-S Aero-Engine Wireless Networked System With Scheduling

Nonlinear control and signal scheduling are the two difficulties for wireless networked control application in aero-engine. For aero-engine nonlinear complex flight conditions, the co-design of dynamic scheduling and robust H-infinity control method analysis was conducted by employing a class of aero-engine T-S (Takagi-Sugeno) fuzzy model based on flight envelop division. For each state space model of the fuzzy rules, the sufficient condition for the asymptotically stability of robust H-infinity controller design under MEF-TOD (Maximum Error First-Try Once Discard) scheduling strategy based on the Lyapunov function and switched system theory is deduced. Then the global fuzzy controller strategy was identified based on the parallel distributed compensation technology, which shares the same fuzzy rules with the T-S model. Finally, a TrueTime simulation example demonstrates the efficiency of the proposed method.
