For the system of the drum water level of circulating fluidized bed boiler,cascade three-element control system is adopted to regulate the drum water level.Particle swarm optimization is introduced to tune the system in order to obtain the opti-mal parameters.The simulation results show that,compared to the conventional tuning method,the scheme provides the control system better control quality,and improves its dynamic and static performance index.
