CloseGapDetermine the rate of flow (action) to close a gap between a quantity and its desired value 
This information is part of the Business Simulation Library (BSL).
The output y is given by the expression:
y = (u_reference  u_current) / u_adjTime
where the time to close the gap (u_adjTime
) can alternatively be a constant (adjTime
). If the adjustement time is zero, then the output y will be zero as well.
adjTime 
Value: 1 Type: Time (s) Description: Time to close the gap 

maxRate 
Value: inf Type: Rate (1/s) Description: Maximum rate feasible 
minRate 
Value: 0 Type: Rate (1/s) Description: Minimum rate feasible 
hasConstantAdjTime 
Value: true Type: Boolean Description: = true, if the time to close the gap is a constant paramater 
invertOutput 
Value: false Type: Boolean Description: = true, if the output is to be multiplied with (1) 
clipOutput 
Value: false Type: Boolean Description: = true, if the indicated rate is to clipped to not exceed limitations 
strict 
Value: true Type: Boolean Description: = true, if strict limits with noEvent(..) (constantLimiter.strict) (clip1.strict)
