摘要
面对复杂生产过程中的多种时变性、非线性、不确定性、大纯滞后以及各种约束条件,预测控制正在经历不断完善的过程。预测控制与各种先进控制方法和智能优化策略相结合,从不同角度改善了传统预测控制方法中存在的模型预测精度不高,滚动优化策略少,反馈校正方法单调等问题。介绍了近年来预测控制的新进展及在火电厂生产中的应用前景。
Predictive control is being perfected continually in the face of the property of the strong dynamic delay and time-varying nonlinear and many restriction conditions of the complex industry process. To integrate advanced control and intelligent control with predictive control for a controlled object, it can be improved that the predictive model precision is not better and the optimal operating algorithm is few and the feedback proofread method is humdrum etc. The development and application of current predictive control in a fire power plant is introduced.
