Equivalent description and stability analysis for discrete-time systems with uniformly distributed uncertainty. (English) Zbl 1485.93325

Summary: We are concerned with discrete-time systems with uncertainty, which is assumed to be uniformly distributed over the unit interval \([0,1]\). To describe this uncertainty, the space \(\{0, 1\}^{\mathbf{N}}\), which is composed of all the infinite 0-1 sequences and endowed with the Haar measure, actually constitutes the underlying probability space. Therefore, it is shown that for stability analysis, such an uncertain system can be transformed into a switching system with switching sequences having maximal entropy. A stability criterion then is derived from this transformation. An illustrative example is included to show the effectiveness of the theoretical results.
