摘要
广义预测控制算法具有控制效果好、鲁棒性强和模型要求低等优点。分析广义预测控制原理及其隐式算法,利用预测信息对控制增量的选取策略进行了改进,并针对该算法在具有大滞后和时变性的电站锅炉过热汽温控制过程中的应用进行了仿真研究。最后通过仿真结果验证了该算法的优越性和可行性。
The generalized predictive control algorithm had several advantages such as good control effect,strong robustness and low model requirement etc.The principle and implicit algorithm of generalized predictive control was introduced and analyzed in this paper,and the selection strategy of the control increment was improved via making full use of forecasting information.And then,the application of improved algorithm was simulation studied to the boiler superheated steam temperature control process with long time delay and time variation in power plants.Finally,the simulation results verified the superiority and feasibility of the improved algorithm.
