基于状态校正的积分对象预测控制算法及其应用
A predictive control algorithm of integral processes based on state correction and its application
摘要
Abstract
For integral processes with large lag, strong dynamic disturbance, the predictive control algorithm based on first-order state correction was proposed. Considering the integral effect of deviation between predictive and actual state, it exerts state correction on the first-order dimension. Thus the controller’s robustness is improved significantly. By simulation experiments, the effectiveness of the state correction algorithm was confirmed. And the algorithm has been adopted for liquid level control of flash tank in a refinery. The practical application results showed that the control effect is outstanding.关键词
