delay3

delay3

delay3 is the system dynamics function that returns a third order exponential delay of the input. If the delay time changes, the input is preserved.

The plot below illustrates how the function works (initialValue = 0.0; delayTime = 5.0):

This function can be called in formulas of system dynamics variables and has two notations:

  • delay3(input, delayTime, initialValue)

    input can be a flow variable, or a numeric expression of any complexity.

    delayTime can be either a constant or a numeric expression (e.g. a function call, or a numeric parameter). It should return a positive number: delay3 function with zero or negative delay time returns NaN (not a number).

  • delay3(input, delayTime)

    A simplified notation of the function. It is used when the initialValue is zero.

Units

input — unit

delayTime — time

initialValue — unit

delay3() — unit

The output units are the same as the input ones.
