【摘要】 针对循环流化床燃烧控制系统的特点,以主蒸汽压力为被控对象,设计一个基于平衡工作点的神经网络与PID的复合控制器。运用神经网络方法在线建立锅炉当前工况平衡工作点,在此基础上通过传统的PID控制实现对主蒸汽压力的控制。仿真结果表明,该控制器对蒸汽压力具有良好的控制性能。更多还原

【Abstract】 This paper analyzes the dynamic characteristic of the controlled object of the stream pressure of CFB boiler in thermal power plant,and presents a new design method of intelligent compound controller based on the balance point.The neural network algorithm is used to adjust the current working point,and then the PID control strategy is used for the stream pressure control.The simulation shows that the intelligent compound controller has better control characteristics than the traditional controller.更多还原
