AI 中文摘要
我们展示了如何计算给定广义状态空间模型的被动半径,该模型表示一个被动系统的有理传递函数,涵盖连续时间和离散时间两种情况。然后,我们利用这一结果构造鲁棒描述符实现。对于连续时间情况,这些实现具有端口-哈密顿描述符形式。对于离散时间情况,类似的结果适用于所谓的归一化实现。在这两种情况下,此类鲁棒实现的计算都与表征传递函数被动性的线性矩阵不等式的特定解相关联。
英文摘要
We show how to compute the passivity radius of a given generalized state-space model of a rational transfer function that represents a passive system, both in the continuous-time and discrete-time cases. We then use this to construct robust descriptor realizations. For the continuous-time case, these realizations have a port-Hamiltonian descriptor form. For the discrete-time case a similar result holds for the so-called normalized realizations. The computation of such robust realizations is linked in both these cases to a particular solution of a linear matrix inequality that characterizes the passivity of the transfer function.
