Abstract
Recently, a strong evolution occurs in the feedback control using frequency
domain
approach. Computer Aided Design tools involving optimisation emerges
as an alternative to
traditional tuning based on frequency diagrams as Bode, Black and so
one. Benefits are impressive:
direct investigation of possible trade-offs, precise analysis of uncertainty
effects and
so one. This evolution does not happen by chance: it is the result
of a rigorous formulation
of classical concepts of automatic control. These results mainly focus
on linear time invariant
systems with the so called H1 approach: its extension to nonlinear
systems is under progress
with the incremental norm approach. This paper purpose is to illustrate
different aspects of this
evolution in a non formal way.
