摘要
针对某765MW联合循环直流锅炉-汽轮发电机组,文中给出了机组输出功率和焓值的并行模糊PID控制系统结构,研究了模糊控制器参数的自适应在线整定方法。首先,分析了联合循环直流锅炉-汽轮发电机组的数学模型,然后,在作者前期工作的基础上,给出了并行模糊PID控制器参数的自适应整定方法,最后,与基本并行模糊PID控制系统进行了仿真对比分析。仿真结果表明,本文所叙述的参数自适应模糊PID控制系统对于降低控制系统振荡,缩短调节时间等方面,其控制效果更优于基本并行模糊PID控制系统。
Based on a 765 MW combinational once-through boiler turbogenerator unit, this paper designs the typical parallel fuzzy control system for the output electric power and enthalpy, and researches the parameter＇s adaptive tuning method of the fuzzy controller. First, it analyses the mathematical model of the once-through boiler turbogenerator unit. Then based on author＇s previous work, given the parameters＇ adaptive tuning method of the fuzzy controller based on author＇s previous work. Finally, the simulation results show that parameter adaptive fuzzy PID controller can effectively reduce control system＇s oscillating and regulating time, whose static and dynamic property is more than the basic parallel fuzzy PID control system.
