Abstract: 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 optimal 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.

Key words: particle swarm optimization, PID control, drum water level, MATLAB simulation

摘要: 对循环流化床锅炉汽包水位控制系统,采用串级三冲量PID控制,应用粒子群优化算法对PID控制器进行参数整定,并获得了最优参数。仿真结果表明,与传统整定方法相比,这种参数整定方案使汽包水位控制系统具有更好的控制品质,提高了系统的静动态特性。
