| Abstract: | In multirate sampled systems, sampling periods are not uniform. This article briefly reviews the existing mathematical models of multirate sampled systems including the linear periodic time-varying model, the frequency domain model, and the continuous time state space model. The corresponding identification methods, such as lifting method, frequency domain method and subspace method, are also discussed. Model selection, consistency, constrained identification, convergence and other problems in the identification of multirate sampled system are deeply discussed. |
