Abstract:

In order to overcome the wide-range load tracking and unknown disturbance issues of an ultra-supercritical boiler-turbine unit, a fuzzy disturbance rejection predictive control approach is proposed using the techniques of fuzzy scheduling, model predictive control and extended state observer. Local state-space models are established on the basis of nonlinearity analysis and subspace identification. To enhance the disturbance rejection capability of the controller, an extended state observer is employed to estimate unknown disturbances and model mismatches. The disturbance estimation enhanced local predictive controllers are subsequently devised based on the local models, the performance of which is further strengthened by incorporating the fuzzy scheduling technique. The simulation results verify the merits of the proposed strategy in achieving satisfactory wide-range load tracking and disturbance rejection performance.
