This paper proposes a discrete state predictive control by introducing a virtual system.To determine the state-space model and the time delay, the subspace identification method, called a CCA (Canonical correlation analysis) method, is applied. The CCA method can judge orders of the system by checking how many singular values of a covariance matrix among output data are near 1. First, it is shown that the time delay system has higher-dimensional orders, and this model can be used to the LQG control for the time delay system. After that, by confirming the number of singular values near 1, the time delay can be identified and used it for the discrete state predictive control. The proposed method is applied to the stable vibration cart type pendulum with time delay inserted in artificially.
