摘要: This paper establishes a necessary and sufficient stability condition of fractional-order interval linear systems. It is supposed that the system matrix A an uncertain fractional commensurate order belongs to [email protected][email protected]<2. Using existence Hermitian P=P^* for complex Lyapunov inequality, we prove robust stable if only there exists such certain type inequality satisfied all vertex matrices. The results are directly extended polynomial
