摘要
针对飞机的直接升力控制问题,设计了一种将动态逆控制器和模糊控制器结合使用的新方法,并在系统参数优化过程中对ITAE准则进行改进。在ITAE准则的基础上,引入对正向误差的积分从而约束系统响应的超调量。通过对单纯直接升力控制模态和垂直平移控制模态的仿真实验,表明文章的模糊动态逆控制器能够实现具备良好鲁棒性的直接升力控制;通过对比模糊动态逆控制器和动态逆控制器的仿真结果,表明模糊动态逆控制器的动态性能和稳态性能优于动态逆控制器。
In order to deal with the problem of direct lift control of aircraft, a new method combining dynamic inverse con. troller and fuzzy controller was designed. In the system parameter optimization process, the ITAE criterion was improved by introducing an integral of the forward error to constrain the overshoot of the system response. Through the simulation ex. periments of simple direct lift control mode and vertical translation control mode, it is found that the fuzzy dynamic inverse controller designed in this paper can achieve direct lift control with certain robustness. And by comparing the simulation results of fuzzy dynamic inverse controller and single dynamic inverse controller, it is found that the dynamic performance of fuzzy dynamic inverse controller is better than that of single dynamic inverse controller.
