| 摘 要： | 提出了一个实现大范围负荷跟踪的火电单元机组智能控制系统．该系统包括设定值调节器、神经网络模糊前馈控制器、模糊反馈控制器和单元机组．设定值调节器根据机组负荷指令提供设定值．前馈控制器采用神经网络模糊控制逼近单元机组的逆稳态特性而得到前馈控制信号，以实现单元机组的大范围运行．反馈控制器则采用模糊控制补偿负荷扰动所引起的单元机组的实际值与设定值的偏差．前馈控制信号与反馈控制信号相加后发出指令到单元机组完成负荷跟踪任务．仿真结果表明，该系统有较好的动态特性，能适应于机组大范围的负荷跟踪．

| Abstract: | This paper proposes a power unit intelligent control system implementing wide range load tracking.The intelligent control system consists of reference governor,neuro-fuzzy feedforward controllers,fuzzy feedback controllers and fossil-fuel power unit(FFPU).The reference governor provides the set points of the system according to the unit load command.The feedforward controllers approximate the inverse steady state behavior of the FFPU using neuro-fuzzy control in order to provide feedforward control signals for the wide range operation of the FFPU.The feedback controllers provide the complementary feedback control signals using fuzzy control.The two kinds of control signals are added to the FFPU to complete the task.The simulation results of the intelligent control system show that it has good dynamic characteristic and suitable for wide range load tracking. |
