Overshoot Characteristics
SIMPLORER 6.0 — Manual 265
>>Basics>Signal Characteristics>Dynamic Performance Parameters
The macro provides the overshoot factor, the maximum overshoot and the time span to reach
the maximum overshoot. The maximum overshoot OVERMAX characterizes the system's ability
to oscillate and is given in percent of final value.
Selecting a start time TSTART greater than zero, the time calculation can be adapted to possibly
occurring time shifts (Maybe a step change of setpoint occurs not before a certain time
span has elapsed.). Start time TSTART and end time TSTOP of rise time calculation have to be
located within Zero and the whole simulation duration (TEND).
For time definitions refer to the following figure:

Dialog Settings
«Input Signal»
Enter a quantity name used in your model sheet in the text box to define the input signal
(RLOAD.I, STEP.VAL, STATE.ST, VAR) or use the pin to connect a quantity. Please note: You
cannot use conservative nodes from circuits as input signal (N0002, GND).
� � «Use Pin»
If the box is checked, the input signal is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
«Setpoint Value»
Defines the setpoint of the input signal. Common parameter type. Enter a numerical value, a
variable, or an expression in the text box.
«Number of Overshoot Factors»
Defines from which number of the overshoot ratio the calculation is started. Enter a positive
integer in the text box.
«Start Time [s]»«Stop Time [s]»
Common parameter type. Enter a numerical value, a variable, or an expression in the text box.
The specified start time (for beginning of calculation) has to be less than the end time (for end
of calculation).
