Study on Improving the Performance of the Aircraft Rudder Loop Based on Fuzzy Control

针对飞机舵回路的工作性能受到非线性特性影响和负载力矩反影响,提出了一种将模糊控制和传统PID控制相结合的方法,分区间对PID控制器参数进行模糊整定,使得飞机舵回路在每个工作区间都具有较好的响应特性,从而改善舵回路的全局性能。文中给出了分析设计过程和仿真结果,证明了该方法的有效性。

For the aircraft rudder loop performance affected by the non-linearity and torque anti-impact, a fuzzy control and traditional PID control of combining methods is given, area between the PID controller parameters of fuzzy-tuning, making the plane rudder loop at each interval has a better response chai＇acteristics, thus improving the overall performance of the rudder loop. In this paper, the analysis design process and simulation results are given to prove the effectiveness of the method.
