摘　　要：对于一个非线性系统 ,利用其近似的线性化模型求出系统的近似逆 ,采用模糊控制方法抑制误差对系统输出的影响来保证系统的最终特性 ,构成一种动态逆模糊集成控制方案 .将这一方法应用在无人直升机的姿态控制中 ,仿真结果表明该方法可以消除无人机未建模动态和不确定性的影响 。The approximate reverse of a nonlinear system was extracted by its approximate linearized model and the fuzzy control was employed to restrain the effect the error produces on the system so as to guarantee the terminal performance of the system, thus constituting a plan of dynamic reverse and fuzzy integrated control. This method was applied to the attitude control of unmanned helicopters and it can remove uncertain effects unmanned helicopters bring about and provide better robustness.
