Model predictive control of the superheater temperature based on a piecewise affine model

Popis výsledku v původním jazyce

The paper deals with one important problem closely connected with the necessity to increase the load following capability of power plants. Its focus is on the control of the main steam temperature at the superheater output. The superheater is a highly nonlinear system and there is little chance that advanced control based on single linearized model may achieve good control performance. The paper shows that nonlinear superheater model can well be approximated with a piecewise affine (PWA) system and controlled using model predictive control (MPC) based on PWA model. The responses to fast wide range load changes (in the range from 50 to 100% of the nominal load) and periodic input disturbances due to irregularities in coal mills are evaluated. It is shown that in both cases MPC control based on PWA model can achieve considerable performance improvement over classical control system based on cascades of gain scheduled PI controllers.
