某改型无人机多回路全包线校正网络优化设计

Optimization of Multi-loop and Full Envelope Corrective Network for a Certain Retrofitted UAV

无人机改型后,一般会遇到原控制器与改型无人机不匹配,而导致部分设计状态点频域响应不满足设计指标的问题。文中针对此类问题,以某改型无人机为研究对象,首先,分析问题并制定了多回路全包线校正网络优化设计方案;其次,基于高度保持回路和侧偏距控制回路,对不满足设计指标的状态点进行了校正网络优化设计;最后,将优化结果应用于其他控制回路,并进行了仿真对比。仿真结果证明,优化后的校正网络具有更好的适配性,能够满足设计指标。

After a certain UAV retrofitted,the problem that frequency-domain response of some design points cannot meet design indicators due to the mismatch between original controller and retrofitted UAV.Aiming at this kind of question,a certain retrofitted UAV has been studied in this paper.Firstly,a optimization scheme of multi-loop and full envelope corrective network was designed after the problem analysis.Secondly,based on height control loop and crossrange control loop,the optimization and simulation of corrective network was designed since the design points cannot satisfy the design indicators.Finally,the simulations and comparisons were applied to other control loops.The simulation results proved the corrective network optimized has better compatibility to meet the design indicators.
