AOA_adc is a simple module that is be written to test the flight behaviour with a Angle Of Attacke sensor.
It only reads the value of an defined ADC port and converts it to radiant. A mode variable named h_ctl_pitch_mode in the stabilization_attitude.c enables to switch between estimator_theta (IMU) and estimator_AOA to control the elevator.
Be aware: This module is in construction. Feel free to upgrade it.
Module Infos
Angle of Attack ADC Sensor
- US DIGITAL MA3-A10-236-N
ModuleXML
- AOA_adc.xml
Code- and headerfile
- sw/airborne/modules/sensors
Settings file
- AOA_adc.xml
Airframe Adjustments
- (1) Insert the software module in the airframe:
<modules>
<load name="AOA_adc.xml">
<configure name="ADC_AOA" value="ADC_6"/>
<define name="AOA_OFFSET" value="-0.135000005364"/>
<define name="AOA_FILTER" value="0.875999987125"/>
<define name="USE_AOA"/>
</load>
</modules>
- Legend:
- The ACS_AOA defines on whitch port the US Digital Sensor is connected to.
- The AOA_OFFSET is needed to adjust the Zero rad mark in the normal flightposition. It can be changed with the AOA_adc.xml settings loaded.
- The AOA_FILTER describes the PT1 filter value of the angle. 0 = no filter
- Define USE_AOA to make the module work.
- (2) Load the settings XML in the GCS: AOA_adc.xml
- (3) Now you can turn on the pitch stabilization by setting the PITCH_Mode to 1
- PITCH_Mode = 0 --> estimator_thata from IMU (default)
