Study of fuzzy control with smith forecast and compensation for aeroengine

Abstract

It is a difficult problem to build the aeroengine model. And it is hard to meet aeroengine control demand by traditional methods. So according these problems, aeroengine models were built including "little deflection" model and "large deflection" models. A fuzzy controller was designed which had the parts of parameter adjustment control and smith forecast and compensation control. The simulation of aeroengine control system which considering actuation mechanism and time delay was carried out. The simulation results show that smith forecast and compensation control can effectively solve time delay influence. The control system has great robustness with the part of parameter adjustment control. The control effect is great for "little deflection" model and acceleration model.
