New library and Parameters

Started Jan 17, 2018 0 Replies

Hello! So I've made a new library that I called AC_NewPID and I've got it all set up. I already included it in the GOBJECTPTR in Parameter.cpp and the k_param_ac_newpid in Parameter.h and I've…Continue

Hello! I've been working with Pixhawk and Mission Planner and I've been trying to get some movement data from the autopilot mode...Let's say I set up a waypoint to the right of the home location..…Continue

Error Computation

Hello guys!So I was wondering if, from the data flash logs, I could simply compute the error by: desired roll - roll or something like that.... However, if I use that method I get an average error…Continue

New library and Parameters

Hello! So I've made a new library that I called AC_NewPID and I've got it all set up. I already included it in the GOBJECTPTR in Parameter.cpp and the k_param_ac_newpid in Parameter.h and I've resolved a lot of the issues with building... After building, I ran it in SITL and I realized that the Parameters in my AP_Param::Group_Info AC_NewPID::var)info[] were not appearing in Mission Planner when I connected it...Is there a way for me to be able to access these values? Or did I miss…See More

Roll Movement on Auto Flight Mode Mission Planner

Hello! I've been working with Pixhawk and Mission Planner and I've been trying to get some movement data from the autopilot mode...Let's say I set up a waypoint to the right of the home location.. When I takeoff the drone... it turns its nose to the right (yaw movement) and then moves forward (pitch movement)... which is correct in terms of following the path... but that means I never get a roll movement... so is there some way to set a roll movement in auto flight mode?Plus in terms of pitch..…See More

Error Computation

Hello guys!So I was wondering if, from the data flash logs, I could simply compute the error by: desired roll - roll or something like that.... However, if I use that method I get an average error that is completely high...My group is currently focusing on minimizing the error, and we wanted to know if we could use CORRELATION to determine its accuracy instead.... We could correlate the desired roll and the actual roll to obtain its similarities...Has anyone ever done this? Do you think it's an…See More

Attitude Control Class

Hello! This might be hard to answer but I was wondering where in the libraries or ArduCopter code the children classes are specified to run instead of the parent?For example... we have the rate_controller_run() virtual function in AC_AttitudeControl which is equated to zero because we won't be using it....see "attach1"But instead we would be using the rate_controller_run() of AC_AttitudeControl_Multi (see "attach2")... which inherits from the AC_AttitudeControl.... But as we can see....…See More

Computing the Attitude Percentage Error

Hello guys! I've been working on the accuracy and stability of the Pixhawk... and I've been wondering how it is to properly compute the percentage error of its flight... So I've been using the telemetry logs since I've only got to the SITL part... However I could not find the best way to solve for the attitude error...For instance we have, desired roll values from the nav_roll to be [0 1 3 1 0] then we have the actual roll to be [0.1 0.9 2.5 0.9 0.1].... How do I compute the percentage error?I…See More

SITL stopped working (Ubuntu in Windows VMWare)

Hello Guys! I've encountered a problem with my Ubuntu in VMWare.... so I've been doing an altitude test for a while with SITL and have been connecting it with Mission Planner in my windows... And so far it was good... but then my SITL stopped working for some reason... I've tried updating all python stuff and nothing worked... I use this scheme on the terminal below:export PATH=$PATH:$HOME/jsbsim/srcexport PATH=$PATH:$HOME/ardupilot/Tools/autotestexport PATH=/usr/lib/ccache:$PATH. ~/.bashrccd…See More

Moment of Inertia in SITL

Hello guys! I know measuring the moments of inertia of inertia about the X,Y, and Z axes... However, in the SITL simulation version, I don't know what values are used for the moments of inertia... Is there like a default value for the SITL?See More

"even just maybe have the mass value saved at a certain variable... and do all stuff with it... maybe change the throttle PID control... or something... anything that has the mass/weight of the drone in the code..."

"I don't get it, you do not know what it is, and would use that parameter for something different ? Or what do you mean ?"

"well... if I wanna add mass to the code... maybe change something or make use of its value... isn't there any variable which at least makes use of its value.... how is it related to the thrust? Thanks!"

Andre K. replied to Ronello Ninettu's discussion Ardupilot ArduCopter add weight to the code
"No, mass is not of interest, and its effect is related to the total thrust and rate of change of thrust available."

Ardupilot ArduCopter add weight to the code

Hello guys! I'm currently working on the PID control of the ArduCopter code... and I was wondering where the mass/weight of the quadrator was considered... if it was considered at all... Even just the parameter name is helpful enough...And may I ask if the paramter AP_MOTORS_THST_HOVER_DEFAULT is related somehow to the weight/mass?Thank you!See More

Install Software In the Loop

Hello guys! I'm a little stupid when it comes to this... but can someone help me with a step-by-step installation of the SITL? I can't seem to accomplish this command:3.

Inertial Sensor Ardupilot - Arducopter 3.3

Hello! I was studying the inertial sensor of the ardupilot... and I was brought to the very last function that I could think of that stores the accelerometer and gyrometer readings.... which are in the AP_InertialSensor.hThere are the _accel[i] and the _gyro[i] as seen in the attached picture...I couldnt find where the values for _accel[i] and _gyro[i] are found... Could anyone help me? Just point me in the right direction... or any class files.. or functions..Thanks!See More

Altitude Control ArduCopter 3.x

Hello! I've been trying to study PID and especially the coding implementations of the PID controller onto the ArduCopter code (which I would use for a quadrotor)... So when I was researching, I found several formulas on the altitude control of the PID which they normally call U1 in online journals (as for the motor inputs)... I've noticed that the altitude control using PID made use of the following formula:U1 = [m/(cos theta * cos phi]*( PID )so I've seen the PID controllers on the code in the…See More
