问题描述
以下是解决模糊逻辑的代码，我尝试从模糊控制系统（scikit模糊库）制作，但遇到错误ValueError: Unexpected input: temprature
import numpy as np
import skfuzzy as fuzz
from skfuzzy import control as ctrl
temprature = ctrl.Antecedent(np.arange(0,15,1),'temperature')
moisture = ctrl.Antecedent(np.arange(0,11,'moisture')
humidity = ctrl.Antecedent(np.arange(0,'humidity')
minutes = ctrl.Consequent(np.arange(0,26,'minutes')
temprature.automf(3)
moisture.automf(3)
humidity.automf(3)
minutes['low'] = fuzz.trimf(minutes.universe,[0,13])
minutes['medium'] = fuzz.trimf(minutes.universe,13,25])
minutes['high'] = fuzz.trimf(minutes.universe,[13,25,25])
rule1 = ctrl.Rule(temprature['poor'] | moisture['poor'] | humidity['poor'],minutes['low'])
rule2 = ctrl.Rule(temprature['average'] | moisture['average'] | humidity['average'],minutes['medium'])
rule3 = ctrl.Rule(temprature['good'] | moisture['good'] | humidity['good'],minutes['high'])
tap_ctrl = ctrl.ControlSystem([rule1,rule2,rule3])
tap_control_system = ctrl.ControlSystemSimulation(tap_ctrl)
tap_control_system.input['temprature'] = 1
tap_control_system.input['moisture'] = 1
tap_control_system.input['humidity'] = 1
tap_control_system.compute()
print(tap_control_system.output['minutes'])
错误：
Traceback (most recent call last):
File "engine.py",line 30,in <module>
tap_control_system.input['temprature'] = 1
File "C:\Users\Toshiba\anaconda3\envs\Fuzzy-System-Project\lib\site-packages\skfuzzy\control\controlsystem.py",line 168,in __setitem__
raise ValueError("Unexpected input: " + key)
ValueError: Unexpected input: temprature
解决方法
这是一个错字。你这里有一个错字：
tap_control_system.input['temprature'] = 1
应该是：
tap_control_system.input['temperature'] = 1
在 Jupyter website 上试用的笔记本：
