The mathematical expression of fractional-order calculus was derived from the fractional-order calculus definition
and then the particle swarm optimization algorithm was applied to identify the fractional-order model for the relationship between the fuel flow and intermediate-point pressure in supercritical power plant.On this basis
a fractional internal model controller(IMC)was designed.Moreover
the control effects of this IMC was compared with that of the conventional integer-order IMC.The results show that the fractional-order IMC this paper designed has better control effect and anti-disturbance ability.
