On Improving Lateral Direct Lift Control System of Aircraft with Improved Dynamic Inversion Decoupling Method

Dynamic inversion decoupling method is usually used in active control technology. For improving lateral direct lift control system of aircraft, we improve dynamic inversion method through combining it with fuzzy control method with correction factors. Subsection 1.1 reviews relevant inform-ation concerning dynamic inversion decoupling method. Subsection 1.2 deals with fuzzy control methods and includes two aspects: (1) our improvement of fuzzy control method;(2)combination of dynamic inversion decoupling method with our improved fuzzy control method. Our improvement of fuzzy control method is that we obtain fuzzy controller with high performance by optimizing correction factors, proportional factors and integral factors. Table 1 gives simulation results and compares robustness obtained with our combined method with that obtained with the usual dynamic inversion decoupling method. The comparison of simulation results shows preliminarily but clearly that our combined method can improve robustness of direct lift control system of aircraft greatly.
