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...

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...

M.Seron,J.Braslavsky,P.Kokotović, Robustification of backstepping against input unmodelled dynamics (1999)

Murat Arcak, Maria Seron, Julio Braslavsky, Petar Kokotovic

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...
