摘要
循环流化床床温由于非线性、大时延和时变性,采用传统PID难以控制。文章提出了一种基于二进制和声优化算法的模糊控制器,并将其应用于循环流化床床温的控制。仿真结果表明,该控制器控制性能相对于传统的PID控制有了较大地改进,具有较强的鲁棒性。
Due to the characteristics of the strong nonlinearity,large time delay and time-varying in Circulating Fluidized Bed Boiler（CFBB）,PID controller can hardly meet the control requirements.Thus,a discrete binary harmony search based fuzzy controller is developed and introduced to optimize the bed temperature in CFBB.The simulation proves that the proposed method,comparing with the PID control,gains a great improvement in control performance and meanwhile has a strong robustness.
