This dissertation shows how to develop wireless networked embedded control systems
(wnecs) in which the controller and the plant are isolated and can only interact
over a wireless network. Many of the new results presented are based on passivity and
scattering theory. In particular we show how to:
1. synthesize discrete time passive, strictly-input passive, and strictly-output passive
systems from their continuous counterparts using a inner-product equivalent
sample and hold (IPESH) block (with an optional passive observer),
