Directing against the existence of such problems as complex off line computing and fairly poor real time performance in actual multi variable algorithm of predictive control, the author designs this multi variable algorithm based on assooiate estimate for predictive and dynamic matrix control (DMC). In the paper, the effectiveness and the stability of this algorithm are analysed; and the method of its program implementation is explained. As indicated by the results from actual control of paper machine, this algorithm is simple, easy of implementation and good in real time performance by which the fairly good effect of controlling can be attained.
