摘要
为了改善传统串级PID主汽温度控制系统的控制效果,提出了采用模糊自适应控制器的串级主汽温控方案.主调节器采用模糊自适应PID控制器,副调节器采用传统PID调节器.利用模糊规则,主调节器PID参数可根据误差信号动态调整.仿真结果表明,该系统在机组负荷较大范围变化时,其控制品质优于传统PID串级控制系统.
In order to improve the effect of traditional cascade PID main steam temperature control system,the paper proposes the cascade control system by using self-adaptive fuzzy controller.The fuzzy self-adaptive PID controller is used as the primary regulator,and the traditional PID is used as a secondary regulator.By use of the fuzzy rule,the PID parameters of the primary regulator can be dynamically regulated according to the error signal.The simulation research shows that the fuzzy self-adaptive PID controller brings about superior control quality to the traditional PID cascade control system when the unit load demonstrates a large range variety.
