Instantaneous power theory has a central role in power systems analysis. Among mathematical settings used for the development of this theory, quaternion algebra has been used for describing electrical variables in recent works. In this context, this

Stability of switching linear systems with switching signals driven by stochastic processes

Autor: Alessandro N. Vargas, Joao Y. Ishihara, Constantin Florin Caruntu

Publikováno v: Journal of the Franklin Institute. 356:31-41

This paper presents conditions to assure the exponential stability in probability for autonomous switching linear systems. The switching signal acting on the autonomous system produces intervals that follow independent, identically distributed stocha

Robust global bimodal rest-to-rest attitude control of rigid body using unit quaternion

Autor: Paulo P. M. Magro, Joao Y. Ishihara, Henrique C. Ferreira

Publikováno v: Journal of the Franklin Institute. 354:3554-3573

This work proposes a hysteresis-based controller with two binary logic variables for the rest-to-rest control of attitude represented by quaternions. The control system has a hybrid nature given by the presence of a switching logic variable that indi
