【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,设计了一个模糊自校正PID控制器并进行了仿真研究。该设计的特点是将常规的PID控制与模糊控制相结合,在PID调节的基础上,采用模糊推理的思想,根据不同的e、ec对PID的参数KP、Ki、Kd进行自动调节。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,and presents a new design method of fuzzy auto-tuning pid controller based on of the stream pressure.The character of the controller is that it can automatically tune the parameters of the pid according to the variables of error.The simulation shows that the fuzzy auto-tuning pid controller has better control characteristics than the traditional controller.更多还原
