The mixed H2/H∞ dynamic output feedback control problem is studied for a class of networked control system in this paper with measurement data missing. The sufficient condition for existence of a dynamic output feedback controller is given by using the technique of the matrix inequalities, such that the closed - loop system is exponentially mean - square stable and guarantees a prescribed H2 and H∞. performance simultaneously. At last, a arithmetic is put forward to optimize the H2 performance or optimize the H∞ performance. And a numerical example is presented to demonstrate the feasibility of the proposed design approach.
