Abstract:
To improve the control performance of nonlinear ultra-supercritical(USC)thermal power units, an improved min-max fuzzy model predictive tracking control(FMPTC)strategy is proposed. First, a T-S fuzzy model is established to approximate the dynamics of the nonlinear boiler-turbine system. Then, based on an extended fuzzy model containing state variables and output variables, a min-max FMPTC is derived for output regulation while ensuring the closed-loop system stability and the inputs in their given constraints. For greater controller design freedom, the developed controller adopts a new state- and output-based objective function. In addition, the observer estimation error is regarded as a bounded disturbance, ensuring the stability of the entire closed-loop control system. Simulation results on a 1 000 MW USC boiler-turbine model illustrate the effectiveness of the proposed approach.
