Mean-square Stabilizability via Output Feedback for Non-minimum Phase Networked Feedback Systems [article]

Weizhou Su, Jieying Lu, Yilin Wu, Minyue Fu, Jie Chen
2018 arXiv   pre-print
This work studies mean-square stabilizability via output feedback for a networked linear time invariant (LTI) feedback system with a non-minimum phase plant.  ...  A numerical example is presented to illustrate the fundamental constraints in the mean-square stabilizability of the networked system.  ...  This is a very hard problem in general since non-minimum phase zeros make the mean-square stabilization via output feedback to be a non-convex problem (see for example [11] ).  ...

Mean Square Stability Analysis of Stochastic Continuous-time Linear Networked Systems [article]

Sai Pushpak, Amit Diwadkar, Umesh Vaidya
2018 arXiv   pre-print
Necessary and sufficient conditions for mean square exponential stability are expressed in terms of the input-output property of deterministic or nominal system dynamics captured by the mean square system  ...  In this technical note, we study the mean square stability-based analysis of stochastic continuous-time linear networked systems.  ...  In other words, the non-minimum phase zeros increase the phase lag of the system, and the controller must utilize extra effort to nullify its effect.  ...
