Abstract :
This paper studies stabilizing data rates for unstable plants with limited data rates in the state feedback path. The effects of limited data rates and time-variant delays are modeled for the case of floating point number representation. Bounds for stabilizing mantissa rates are obtained and some interesting special cases are highlighted. The first order case is discussed in detail and a number of new results for stabilizing data rates are shown.
