A ROBUST STABLE PI CONTROLLER DESIGN IN TIME-FREQUENCY DUAL DOMAINS FOR AIRCRAFT ENGINE
N. Liu, Shanghai Aircraft Design & Research Institute, China
For the parameters uncertainty of aircraft engine brought by nonlinearity or unit difference, an optimal PI controller with robust stability satisfying the specified gain and phase margins design method in time-frequency dual domains is proposed. This method is applied to the aircraft engine, and the simulation results validate the high control quality, and the robustness is also tested.
