直升机飞控系统鲁棒性验证的无迹变换方法
Unscented transformation method for robustness verification of helicopter flight control system
摘要
Abstract
In response to the large computational load and extended processing time associated with the Monte Car-lo method in the robustness verification of helicopter flight control systems,this paper proposes an unscented trans-formation method for such verification.This method employs particle swarm optimization for determining the uncer-tain parameters.Using the helicopter's yaw channel as a case study,the unscented transformation method's perfor-mance in robustness verification is compared with that of the Monte Carlo method.The results show that the un-scented transformation method significantly enhances computational efficiency while maintaining comparable accura-cy to the Monte Carlo method in the robustness verification of helicopter flight control systems.By adjusting param-eter values to modulate the distance between sampling points and the sample center,this method is also suitable for the robustness verification of high-dimensional helicopter flight control systems.关键词
