摘要
影响模糊控制器动态性能的因素有多方面 ,如模糊控制规则、模糊推理和模糊判决方法等 ,其中比例因子 (量化因子 )对其动态性能有较大的影响 为了探讨各因子的影响 ,通过Matlab仿真语言对由二阶被控对象构成的模糊控制系统进行了仿真研究 方法是预先选定一组理想的参数 (包括被控对象参数和比例因子 ) ,分别改变比例因子 ,观察系统在阶跃信号作用下的响应 最后根据实验结果得出 :三个比例因子对模糊控制器动态性能的影响各不相同
There are many factors that affect the dynamic performance of the fuzzy controller, for example, fuzzy control rules, fuzzy induction and fuzzy judging methods, and so on. Among them scaling factors have great effect on it . In order to demonstrate the effect of scaling factors, a Matlab simulation is made by controlling a two order fuzzy control system . In the experiment ,after presetting a set of reasonable parameters ,including the parameters of the subject controlled and the scaling factors, the system response is observed by changing scaling factors respectively when the system is taken by a step signal. From the results of the experiment it can be concluded that the effects of the scaling factors on the dynamic performance of the system are different from each other. Meanwhile a selection principle and points for attention are introduced in the process of designing the fuzzy controller.
