摘要
提出了一种基于微分进化算法(DE)的自抗扰控制器设计方法;在对飞机短周期运动进行分析的基础上,设计了典型状态下自抗扰纵向飞行控制器;针对所设计控制器可调参数多的问题,对各控制器参数进行了分析,并利用微分进化算法对控制器进行了参数整定;仿真结果表明,经DE算法整定的自抗扰控制器实现了实时指令信号跟踪控制,调节时间小于1.5s,超调量小于2%,具有良好的动态性能;在摄动条件下,舵偏角振荡被抑制在25°以内,显示了较强的鲁棒性。
An ADRC controller design plan for pitch attitude control based on differential evolution (DE) algorithm is proposed in this paper. After analyzing the short--period mode of motion, the paper gives an ADRC design plan to improve the flight control performance under typical estate. There is disadvantages on the controller designed for its excessive abundance of parameters. In order to solve the problem, the DE algorithm is applied to parameter tuning of ADRC after studies of the parameters. The result of the simulation suggests that the ADRC controller tuned by DE algorithm actualizes real--time tracking of the command signal, for the adjust time and overshoot are less than 1.5s and 2 %, and the elevator angular oscillation is suppressed in 25° in the condition of perturbation, the controller achieves high dy namie performance and robustness.
