Sine and Cosine at xml

[matheusdarocha]

Good night.

I want to write a script which the elevator deflection is a sine curve.
Does anyone know how to use sin and cosine at xml script?

thanks

I guess you can start from the script c172_elevator_doublet.xml which as far as I can tell does exactly what you are describing:

jsbsim/scripts/c172_elevator_doublet.xml

Lines 94 to 106 in dd97e99

	<set name="fcs/aileron-cmd-norm">
	<function>
	<sin>
	<product>
	<difference>
	<property> simulation/sim-time-sec </property>
	<value> 25 </value>
	</difference>
	<value> 3.1415927 </value>
	</product>
	</sin>
	</function>
	</set>
