摘　　要：针对直升机大包线飞行控制问题,以模型逆理论为基础,引入生物免疫应答机理和模糊控制方法,提出了模糊免疫自适应模型逆控制系统设计方案。该方案通过设计模糊免疫在线补偿模块,自适应补偿由近似逆模型带来的模型逆误差,实现大包线飞行控制。与神经网络自适应控制方法的对比仿真结果表明,本方案实时性好,在大飞行包线下能够很好地实现控制目标;在舵面受损、输出存在干扰时体现出较强的鲁棒性;且系统具有良好的三轴姿态解耦能力。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.
