| 中文摘要 |
| 针对城市固废焚烧过程炉膛温度控制精度低且控制器更新频繁的问题, 本文提出一种基于事件触发机制的RBF–PID(ET–RBF–PID)炉膛温度控制方法. 首先, 构建RBF–PID控制器, 通过梯度下降算法和递归最小二乘算法在线更新网络参数, 同时引入动量因子的平方及参数的动量项来更新控制器参数, 以提高控制精度; 其次, 设计基于固定阈值的事件触发条件作为控制器更新条件, 以减少控制器频繁更新带来的机械磨损; 最后, 基于北京某城市固废焚烧厂实际数据进行炉膛温度控制仿真实验. 实验结果表明, 设计的ET–RBF–PID控制器能够精准地跟踪炉膛温度, 相比于传统的基于时间触发的PID控制器和RBF–PID控制器, ET–RBF–PID控制器在实现炉膛温度精确控制的同时能有效减少控制器更新次数. |
| 英文摘要 |
| To solve the problem of low accuracy and frequent controller updates in the furnace temperature control of municipal solid waste incineration process, a novel method of furnace temperature control method based on the eventtriggered mechanism RBF–PID (ET–RBF–PID) is proposed. Firstly, the RBF–PID controller is constructed, the network parameters are updated by gradient descent algorithm and recursive least squares algorithm. At the same time, the square of momentum factor and the momentum term of parameters are introduced to update the controller parameters, so as to improve the control accuracy. Secondly, a fixed threshold event-triggered condition is designed as the controller update condition to reduce the mechanical wear caused by frequent controller updates. Finally, the furnace temperature control simulation experiments are conducted based on the actual data of a municipal solid waste incineration plant in Beijing. The experimental results show that the designed ET–RBF–PID controller can accurately track the furnace temperature, the ET–RBF–PID controller can reduce the number of controller updates significantly while achieving accurate furnace temperature control compared with the traditional time-triggered PID controller and RBF–PID controller. |
