STATE-SPACE SOLUTIONS TO H-INFINITY SAMPLED-DATA CONTROL PROBLEMS

摘要

This paper considers a general sampled-data control problem with band limited continuous-time exogenous inputs. New results on the construction of H-infinity controllers are presented using the chain scattering-matrix formalism. This results in a relatively simple method in transfer function domain. A generator for H-infinity controllers is obtained by solving two coprime factorizations which are required to solve a continuous-time and a discrete-time algebraic Riccati equations in state space.
