In this paper, the L2-L preview control problem of discrete-time periodic systems is studied. By introducing auxiliary variables and replacing the usual state difference with the difference between the system state vector and the input vector and the corresponding auxiliary variables, a periodic augmented error system is constructed. As a result, the L2-L preview control problem is converted into an output feedback control problem. For the augmented error system, sufficient conditions are derived to assure the asymptotic stability with an L2-L performance by the Lyapunov second method and LMI technology. A numerical simulation example illustrates the effectiveness of the results.
