| 中文摘要: |
| 针对基于专家切换策略的焦炉集气管压力变结构控制方法具有动态切换特性差的缺点和集气管压力在不同工况切换时容易导致压力出现振荡和超调的现象，提出了一种基于平滑切换策略的集气管压力变结构控制方法。该方法根据集气管分管压力在不同工况下具有的动态特性，选用基于满意聚类的T S模糊模型建立相应的动态子模型，并采用相应的模糊子控制器进行控制。为保证子模型切换过程状态轨迹的平滑性，采用监督级控制器动态切换子模型及相应的子控制器。仿真和实际效果说明了该算法的有效性。 |
| 英文摘要: |
| The shortcomings of the variable structure control for the gas collector pressure in coke ovens based on the expert switching strategy, such as the poor dynamic switching property, the pressure instability caused by condition switching, are analyzed technologically, and based on this, a new variable structure control method based on the smooth switching strategy for gas collector pressure is proposed. The method is described as below: According to the difference of industrial condition, the corresponding dynamic sub model is built by using the Takagi Sugeno fuzzy model based on the fuzzy clustering satisfied method, and the corresponding fuzzy controller is chosen to control the pressure. In order to ensure the track smoothness of the sub model, the sub model and the corresponding sub controller are dynamically switched by using a supervisory level controller. The simulation and practical application results demonstrate the validity of the method. |
