Abstract :
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 L 2-induced norm minimization, subject to a wordlength constraint
