On stability and performance of sampled-data systems subject to wordlength constraint

In this paper we study the effects of finite-precision controller implementation on the stability and performance of sampled-data systems. A framework is presented in which these effects can be analyzed from a statistical point of view. We analyze the behavior of finite-precision controllers at fast sampling rates and consider the problem of /spl Lscr//sub 2/-induced norm minimization, subject to a wordlength constraint.<
