Detailed Description

Author

Alessandro Collicelli System excitation pure sine wave

This is the module implementation for the a sine wave input. Use sys_id_wave by adding the module to your airframe file and adding the following line to the top of the <command_laws> section of your airframe file:

<call fun="sys_id_wave_add_values(autopilot_get_motors_on(),FALSE,values)">

In the GCS you can then start and stop the wave, change wave frequency. Documentation of the specific options can be found in the module xml file.
