Tutorial: Kalman Filter with MATLAB example part2

[gravisan]

I am slightly confused about why you need u(t) * B here? what what is a(t) ? ( i.e. your value for u(t) ) - since you cannot apply a force the bird - shouldn't acceleration be part of the state?

[Jdjagjmdat]

you have a radical imagination :D

Hello internet! :) See channel bulletin for links to code!

At time 9:30

how come Ex is a 2x2 matrix and you are adding this to 2x1 columns in top equation?

[MrTruquete]

great tutorial, thanks! Now there is something I don't get. You say that cov(P,V)=std(P)*str(V). From looking at the definitions of cov and std, I don't understand how this can betrue. Are you assuming sometehing we don't know? thanks again, really nicely done

you make elec systems intracractive keep on

[benzbubblecat]

you say "matrices" when you mean to say "matrix" and it's sort of confusing at times

Thank you it was very informative

Hi Scienceguy :D

Thanks a lot for the informatinve video. I was wondering since the ninja is using the kalman filter algorithm, how come he has access to the acceleraation of the quail?

Also, pls email me the code @ zhang.feng16@yahoo.com

I must say you did you great job man. You simply rock :D

very pedagogical lecture set, thanks alot i really like this way of teaching,

you may will be a great proffesor in future, good luck.

kindly send me the matlab code:

thanx.

Great lecture, but isn't there a small error in the measurement position prediction matrix? At time 07:40 you add P at t-1 and V at t-1 into the Xbar at t matrix, shouldn't these be P at t and V at t instead?

[TheScienceguy3000]

@BluelightUAV  ack! yes..you are correct.. wish there was a way to send a cookie online :)... thx for noticing! it's the predicted measurement..so it's the prediction at time t...not a prediction about the past...lol..we already know the past :) thx again

Instead of a quail, I have a gyro on a plane. The gyro is measuring angular rate change about the fuselage - if a wing goes up the gyro will measure this, and my motor command, will move it back. Where you have 2 equations (quail position and vel) I propose to have only one describing the angular rate (AR) of my wing as: AR (at t) = AR (at t-1) - Acceleration (at t) * t. My acceleration is that of the angular rate (ie its change caused by my control signal). Reasonable?

@TheScienceguy3000 Can you please me the code at zhang.feng16@yahoo.com I love your explanantion and really want to understand this . please help! I will really appreciate it. Now that you have explained the concept so well, pleaese please help!

[coolzorex]

thank u sooooo much , the way u explained is "AWESOME " totally out of the box .

thank you for this wonderful contribution of yours for students like us.

[TheScienceguy3000]

@qasmii sure thing, just message me your email (probably don't wanna put it here, unless your love spam :)

at the end the link to part 3 says "Video removed by user, sorry about that" but if you pick part 3from the list on the right side it works.

I had trouble reading the 't' and 'z' subscript and what was 'C' ?

[TheScienceguy3000]

@iBradleyAllen

thanks! i fixed it, and, yea, I need a better camera, and a better hand :P. C is a coefficient, check out the third vid too see it all again, should make it clearer, else, just shoot me a message. thx!

He's gonna use the kalman filter to track the quail XD
