Abstract
This paper proposes a fractional-order PD controller to suppress the vibration of the typical pipeline system of a nuclear power plant. In view of the characteristics of typical pipeline systems of nuclear power plants, mathematical models are established and dynamic equations are derived to make complex systems digitized for analysis and research. A piping system vibration damping controller based on fractional-order PD control is designed. The fractional-order PD controller introduces a differential order on the basis of the traditional integer-order PD controller to improve the matching degree of the model. Under this system structure, the quadratic performance index is designed, and the particle swarm optimization algorithm is used to optimize the controller parameters to optimize the effect of suppressing vibration. The simulation results show that in the typical pipeline system of nuclear power plant, the fractional-order PD controller designed by this method can suppress the vibration of the system better than the traditional integer-order PD controller.
