GAP准则在驾驶员诱发振荡预测中的应用
Application of GAP Criterion in Prediction of Pilot Induced Oscillations
摘要
Abstract
Along with flight control of electric drive high plus widely apply to advanced large-scale aerotransport and advanced bat tleplan, flight safety problem caused by pilot induced oscillations, the GAP criterion was applied to predict pilot induced oscillations, the sinusoidal input/triangle output describing function model of rate limiting was built and the Neal-Smith pilot model was improved. The describing function method is proposed to investigate the mechanism of PIO. The calculation method of GAP criterion is attained. Finally, the PIO sensitivity of a type of fighter is predicted by GAP criterion and the results are verified by simulation. The results prove that GAP criterion has specific physical significance and illustrative results, calculate efficiently, and can predict the occurrence of PIO accurately. The important theoretical references can be provided for designing flight control systems.关键词
