Summary: This article studies the problems of \(H_{\infty }\) output tracking performance analysis and controller design for Networked Control Systems (NCSs) with time delay and packet dropout. By using Linear Matrix Inequality (LMI)-based method, \(H_{\infty }\) output tracking performance analysis and controller design are presented for NCSs with constant sampling period. For NCSs with time-varying sampling period, a multi-objective optimisation methodology in terms of LMIs is used to deal with \(H_{\infty }\) output tracking performance analysis and controller design. The designed controllers can guarantee asymptotic tracking of prescribed reference outputs while rejecting disturbances. The simulation results illustrate the effectiveness of the proposed \(H_{\infty }\) output tracking controller design.
