摘要
Abstract
As the superheated steam temperature of thermal power units has characteristics of great inertia,pure time delay and strong disturbance,the generalized predictive control strategy was adopted into cascade temperature con-trol system.Through rolling optimization of objective function,estimating and correcting the model of controlled ob-ject at each sampling time,and using recursive algorithm to reduce online computation work,the computation time was reduced and real-time of the algorithm was enhanced.The simulation comparison results prove that,with low pa-rameter drift,stability and better economy,the proposed algorithm has good control performance in superheated steam temperature control.关键词
