Abstract

This paper firstly presents the linear mathematic models with single sampling rate and multirate sampling rate for one continuous time plant respectively according to the structure of networked control systems. Secondly, based on the models, the corresponding of the discrete linear quadratic performance index function are obtained using discretize the continuous linear quadratic performance index function, and derive the direct relationships between the weighting matrix. Ultimately, the simulation results with Matlab show the effectiveness of the derivation.
