Generalized Predictive Control Strategy of O/C Ratio Control for an IGCC Gasifier

O0632. In this paper, considering the large time lag, high coupling, nonlinear of the gaisifer working process and the traditional control methods are unable to handle it very well, an improved identification method is first introduced via adding identification supervision level. Then an advanced control strategy based on generalized predictive control algorithm is proposed. Finally, compared with the common PID controller, the simulation results indicate that the GPC controller shows a much better performance in set-point tracking ability as well as disturbance rejection and the model-mismath test result is acceptable.
