广义Delta算子系统的无源性分析

Passivity Analysis of Linear Singular Delta Operator Systems

针对广义系统的无源性分析,本文采用Delta算子方法,建立了广义系统的Delta算子模型,并利用广义系统的离散模型与Delta算子模型之间的关系,给出了广义Delta算子系统容许且严格无源的充分条件,通过数值算例,验证了该判别条件的有效性。

For the problem of passivity analysis for singular systems, we first adopt delta operator method and set up the delta operator model for a linear continuous singular system. Then, by using the relation- ship between the discrete model and the delta operator model of the linear singular continuous system, we obtain a sufficient condition guaranteeing the linear singular delta operator system admissible and strictly passive. Finally, the results given in this paper are demonstrated by some numerical examples.
