Hybrid modelling and control of a power plant three-stage reheater

Popis výsledku v původním jazyce

The problem of modeling and control of a three-stage steam reheating process is considered. Its mathematical model is marked by considerable nonlinearity. Moreover, switching of dynamic behavior occurs as individual reheat stages are bypassed depending on the value of manipulated variable. Consequently, there is a little chance that replacing the traditional control system based on cascade PID/PI loops with advanced control methods based on single linearized model may bring any performance improvement.However, both of these features make the steam reheating process a suitable object of modeling with a hybrid model in the form of a PWA system. Hybrid MPC based on this model then becomes a promising candidate approach to control. This paper describes the results of PWA modeling of the steam reheating process. A good agreement of responses between PWA model and nonlinear first principles model is shown. Following the development of this model, the design of a hybrid MPC controller is out
