Author present a direct generalized predictive control algorithm based on Grey Model GM (1,2) in this paper. In this algorithm, we use two identifiers to estimate the parameters of plant and close-loop system, and get the parameters of controller. Because we regard the plant as Grey System, we found it easier to identify parameter based on Grey Model than to do it based on CARIMA model. Thus, real-time property is advanced greatly. The simulation results show efficiency of the algorithm.
