针对无人机舵面破损故障，开展无人机控制系统容错性能边界估计方法研究。通过引入舵面破损故障特征参数，建立了舵面破损故障与控制系统特征多项式间的关系；结合无人机飞行品质，将容错性能边界估计问题变为区间特征多项式的广义稳定性问题；然后利用Soh多项式引理解决一类广义稳定区域的稳定问题，并对另一类广义稳定区域，利用映射变换的方法，将广义稳定问题进一步转化为区间特征多项式的稳定性问题，从而可以利用Hurwitz稳定性判据进行分析；最后通过具体算例证明了该方法的可行性。
針對無人機舵麵破損故障，開展無人機控製繫統容錯性能邊界估計方法研究。通過引入舵麵破損故障特徵參數，建立瞭舵麵破損故障與控製繫統特徵多項式間的關繫；結閤無人機飛行品質，將容錯性能邊界估計問題變為區間特徵多項式的廣義穩定性問題；然後利用Soh多項式引理解決一類廣義穩定區域的穩定問題，併對另一類廣義穩定區域，利用映射變換的方法，將廣義穩定問題進一步轉化為區間特徵多項式的穩定性問題，從而可以利用Hurwitz穩定性判據進行分析；最後通過具體算例證明瞭該方法的可行性。

The boundary estimation algorithm of fault-tolerance performance was researched.By introducing the characteristic parameters of control surface dilapidation,the relationship between the control surface dilapidation and the characteristic polynomial of the control system was established .Based on the UAV flight quality,the boundary estimation problem of fault-tolerance performance was converted into a generalized stability problem of interval polynomials.Then,one class of stability problem of generalized stable region was solved by using Soh polynomial lemma.And the other class is transformed into a stability problem of interval polynomials,which can be analyzed by the Hurwitz stability criterion.Finally,a specific example was adopted to prove the feasibility of the method.
