An improved generalized predictive control algorithm and its application in unit plant coordinated control system

A new predictive control algorithm using full information of predictive information is proposed in this paper. In this algorithm, it takes full advantage of predictive information, the future optimize control variable is introduced to the current control action at k time. Compared with the generalized predictive control algorithm, the improved algorithm reduces overshoot and ensures good tracking effect. From the model of a 500MW boiler-turbine coordinated control system, simulation studies demonstrate effectiveness of the algorithm.
