In this study, finite‐time passivity of switched non‐linear systems is developed. First, a finite‐time passivity concept is proposed using multiple storage functions. Second, a switching law is designed to make a switched non‐linear system finite‐time passive. Third, on the basis of the proposed concept, finite‐time passivity properties are investigated. On the one hand, finite‐time passivity can induce finite‐time stability. On the other hand, finite‐time passivity is preserved under the feedback interconnection and parallel interconnection. Furthermore, the merging switching signal technique is employed to make an interconnected system finite‐time passive. Finally, an example is provided to demonstrate the effectiveness of the obtained results.
