| 摘要: |
| 普通的模糊控制器是以误差和误差的变化作为输入量，类似常规PD控制器的作用，存在超调、抗干扰能力差的弊端。为改善模糊控制器的控制特性．采用基于解析表达式的模糊控制规则。提出模糊控制按照误差和误差变化的情况．合理地调整误差和误差变化权重，实现控制规则的在线自调整结构，并在Matlab环境下以典型的二阶环节为例对其进行了仿真实验。结果表明．设计的在线自调整模糊控制器提高了模糊控制器的动态和稳态特性及抗干扰能力，而且简单、实用，具有一定的通用性。 |

| Abstract: |
| With functions as PD controller,general fuzzy controller takes error and error change as its input parameters,which has over shoot and poor anti,disturb ability. A fuzzy control rule based on analytic expressions is adopted to improve the control characteristics. The rights of error and error change are adjusted according to their variations to realize the online self,adjusting structure of fuzzy control rule. A typical two,order system is simulated with Matlab. Results show that the controller designed improves the dynamic and steady characteristics and anti , disturb ability. Fur,thermore,it is simple,practical and universal in a certain degree. |
