| 摘 要： | 以某型无人机为控制对象,采用改进性能指标的输出反馈LQR技术进行无人机纵向控制律设计,简化了设计的复杂性。利用获得的控制律进行数字仿真及半物理仿真验证,结果表明,无人机的俯仰角响应能在6 s后进入稳态,稳态误差为0,超调量小于20%;在整个仿真过程中,空速变化非常小,在25 s左右达到稳态,达到了设计指标要求,从而证明该方法的简便可行性。

| Abstract: | In the course of longitudinal control law design,with an unmanned air vehicle(UAV) took as a control object,the design obtained simplification to a great extent by means of the linear quadratic regulator(LQR) of output feedback,which improves capability index.The digital simulation is accomplished with the obtained control law,and simulation results show that the system possesses good transient response,and meets requirements,and proves that the design is simple and feasible. |
