【问题描述】:
我在定义匹配规则时遇到了困难。
(defrule set-current
?desAct <- (Actuator (name 0) (StrokeLength ?sl) (Force ?f)
(nominalCurrent ?c3))
(test (eq ?c3 0)) ; I have defined this to change only if value is not
; set yet
?act <- (Actuator (inputVoltage ?v1) ; actuator that has matching slots
(StrokeLength ?sl1)
(nominalCurrent ?c1))
(test (eq ?sl1 ?sl)) ; for same stroke length I want to modify
; nominalCurrent of ?desAct
=>
(modify ?desAct (nominalCurrent ?c1))
)
?desAct 表示我想根据基于某些标准的其他现有事实更改哪些插槽值。 我不确定为什么这条规则不会因为以下事实而触发:
f-4 (MAIN::Actuator (name 4) (inputVoltage 12) (Force 17) (StrokeLength 10) (length 62) (width 18) (height 15.1) (motorType DC) (speedAtNomLoad 25) (weight 28) (nominalCurrent 0.46) (highTemp 50) (lowTemp -10) (price 90) (dutyCycle 20))
f-9 (MAIN::Actuator (name 0) (inputVoltage 12) (Force 17) (StrokeLength 10) (length 10) (width 10) (height 10) (motorType DC) (speedAtNomLoad 0) (weight 0) (nominalCurrent 0) (highTemp 0) (lowTemp 0) (price 0) (dutyCycle 0))
我期望名称为 0 且具有此规则的执行器具有与 f-4 相同的nominalCurrent,但规则不会触发。
