【人工智能II】洗衣机控制的模糊推理模型

参考学习博客：模糊推理模型----模糊控制洗衣机（人工智能课后作业）
python代码：

'''
洗涤时间范围【0,60】，污浊度以及油渍的范围【0,100】
输入：污浊度 Stain（SD、MD。LD） 油脂度 Oil（N、M、L）
输出：洗涤时间 time（VS、S、M、L、VL）
'''OIL = 100.0
Stain = 100.0'''
创建结构体elem
'''
class Myclass(object):class Struct(object):def __init__(self, oil, stain, result):self.oil = oilself.stain = stainself.result = resultdef makestruct(self, oil, stain, result):return self.Struct(oil, stain, result)'''
计算污浊度:1 表示 SD，2 表示 MD，3 表示 LD
'''
def ruleMD(stain):if stain < 0 or stain > 100.0:return 0.0else:if stain >= 0 and stain <= 50.0:return stain / 50.0else:return (100.0 - stain) / 50.0def ruleSD(stain):# SD的部分结果，当输入参数在0和50之间时使用result = (50.0 - stain) / 50.0returnMDresult = ruleMD(stain)# 与MD的值进行比较，相同则返回SD；否则，就取大值if result < returnMDresult:return 2.0else:return 1.0def ruleLD(stain):# LD的部分结果，当输入参数在0和50之间使用returnMDresult = ruleMD(stain)result = (stain - 50.0) / 50.0# 结果与MD的结果进行对比，得出最准确的值if returnMDresult > result:return 2.0else:return 3.0'''
计算油脂度:1 表示 N，2 表示 M，3 表示 L
'''
def ruleM(oil):if oil < 0 or oil > 100.0:return 0else:if oil >=0 and oil <=50.0:return oil / 50.0else:return (100.0 - oil) / 50.0def ruleN(oil):if oil < 0 or oil > 100.0:return 0else:# N的部分结果，当输入参数在0和50之间使用result = (50.0 - oil) / 50.0returnMresult = ruleM(oil)# 与M相比，相同则返回N；否则就返回值大的一个if result < returnMresult:return 2.0else:return 1.0def ruleL(oil):returnMresult = ruleM(oil)result = (oil - 50.0) / 50.0if result < returnMresult:return 2.0else:return 3.0'''
总函数计算，计算洗涤时长并输出：
VS: SD N
S: MD N
M: SD M   MD M   LD N
L: SD L   MD L   LD M
VL: LD L
'''
