We employ the discrete-time lifting technique to reduce the multirate preview control problem to a single-rate one. By the standard LQ optimal preview control theory, we characterize the optimal multirate preview controller in terms of periodic feedback gain matrices which are obtained from the solution to a certain algebraic Riccati equation. A numerical example is included to illustrate the applicability of the present design method. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
