In this paper, a method is presented to determine the control forces using several output values which are predicted by a short-term prediction method of time series based on chaos theory assuming that the disturbances of the system are not measurable. The concept of the forward horizon is important for such predictions. The forward horizon is defined for the time series to be predicted and represents the number of values near future which are used for determination of control forces. A method is also proposed to calculate the forward horizon for output time series. The control forces are consist of the predictive control part and the feedback control part by linear feedback theory. The predictive control method proposed in this paper is applied to a numerical example in a rotating disk simply supported by two rigid bearings. The effectiveness of the proposed method is shown by the control results.
