Control over signal-to-noise ratio constrained channels: stabilization and performance (2005)
Freudenberg, Jim, Braslavsky, Julio, Middleton, Rick
Previous papers have considered the problem of using linear time invariant control to stabilize an unstable plant over a signal-to-noise ratio constrained communication channel, and have shown that...

Freudenberg, Jim, Braslavsky, Julio, Middleton, Rick
Previous papers have considered the problem of using linear time invariant control to stabilize an unstable plant over a signal-to-noise ratio constrained communication channel, and have shown that...

Abstract---We present two redesigns to robustify backstepping control laws against dynamic uncertainties at the input of the plant. In the first redesign we construct a passivating control law from a...
Robustness of zero shifting via generalized sampled-data hold functions (1997)
Jim Freudenberg, Rick Middleton, Julio Braslavsky
Abstract--- In this paper we study robustness and sensitivity properties of a sampled-data feedback system with a Generalized Sampled-data Hold Function (GSHF). We argue that shifting nonminimum...
On a key sampling formula relating the Laplace and Z transforms (1997)
Julio Braslavsky, Gjerrit Meinsma, Rick Middleton, Jim Freudenberg
This note provides a new, rigorous derivation of a key sampling formula for discretizing an analogue system. The required conditions are formulated in time-domain, and give a clear characterization...
