Introduction 動機 : – 冷氣機太笨

Senario 室溫 溼度 冷氣強度

I/O variables 室溫 溫度低 : 0~20 溫度中 : 15 ~ 28 溫度高 : 25 ~ 45 溼度 溼度低 : 0~20 濕度中 : 15 ~ 28 濕度高 : 25 ~ 45

I/O variables 冷氣強度 冷氣強度低 : 0~15 冷氣強度中 : 12 ~ 23 冷氣強度高 : 20 ~ 40

Rules IF: x1( 溫度 ) is tl “and” x2( 濕度 ) is hl Then: output( 冷氣強度 ) is ch ch cm chcmcl cmcl 溫度 溼度 冷氣強度 TlTmTh Hl Hm Hh
