英文摘要
      For an ultra-supercritical power unit, to deal with its nonlinear characteristics, time-delay and coupling between units, we analyze the coordinated control system with three-input and three-output, and propose the multivariable constrained predictive control (MCPC) based on the double-layer construction of the power unit. The scheme of the MCPC for the ultra-supercritical power unit based on the step-response model is given, and its associated algorithm is developed in details. Simulations of the proposed control method and traditional PID control method are performed for comparison. The results of the proposed control method show less fluctuation in temperature, fuel flow and feed water flow of the units, and faster compensation response to load variations.
