Study on Fuzzy Immune Adaptive Model Inversion Control System for Helicopter Flight

A novel control scheme, fuzzy immune adaptive model inversion control, was put forward aiming at the large flight envelope control problem for helicopter. The proposed scheme was designed based on model inversion theory, biology immune response mechanism and fuzzy control method. It could implement effective control throughout large flight envelope via the design of fuzzy immune online-compensation element. Simulation results, comparing with the neural network adaptive control method, show the scheme can achieve accurate attitude commands tracking throughout large flight envelope with better real-time performance. Strong robustness has been demonstrated in the case of control surface damage and sensor output noise. Good three-axis uncoupled performance has also been shown.
