摘要 介绍了分数阶线性定常系统的状态方程描述和传递函数描述.运用拉普拉斯变换和留数定理,给出并证明了分数阶线性定常系统的内部和外部稳定性条件,并讨论了其相互关系.以一个粘弹性系统的实例验证了上述方法的正确性. The state-space representation and the transfer function representation of fractional order linear time-invariant systems are introduced. Internal and external stability conditions for fractional order linear time-invariant systems are given using Laplace transform and residue theorem. An example of a viscoelastic system is given to show the effectiveness of the proposed methods.
