摘要：
This paper concerns output feedback passification and adaptive output feedback stabilization problems of switched discrete-time nonlinear systems. First, passivity concept is proposed to describe the overall passivity of switched discrete-time nonlinear system without requiring the passivity of active subsystems. Then, the conditions to be passive for such system are provided. Second, the output feedback passification is achieved under a given switching signal, when switched zero dynamics system is passive. Furthermore, adaptive output feedback stabilization problem is solved by using the output feedback passification method. Third, a time-dependent switching signal is designed to guarantee switched zero dynamics system passive. Finally, two examples are presented to verify the effectiveness of the proposed methods.
