    Need Help Designing a Linear Controller for Yaw Motion of a Hexacopter?

    Of course t_m is the time constant, not tau_m*s

    Need Help Designing a Linear Controller for Yaw Motion of a Hexacopter?

    Hi everyone, I am to design a linear controller for the yaw motion of a hexacopter. My professor gave me this simplified version of the motion (in picture) . However I am trying to derive it myself, but I really can't get my head around it. Any help would be appreciated thanks

    Linux: copy folder from one user to another

    Hello, I'm having trouble copying some folders from one user to another. I've attempted something like this: cp -r /olduser/folder ./newuser/folder it just tells me no such file or directory Can anybody please help ? Thank you

    How to Convert Lead Compensator Output to PWM for Hexacopter Height Control?

    I just found out, that it's how the Arduino board works, you write 0-255, where 0 is 0% duty cycle, and 255 is 100 % duty cycle

    How to Convert Lead Compensator Output to PWM for Hexacopter Height Control?

    That is actually a very good question, what I can see from the data that was given to me is that the transfer function for the motor was derived by subjecting it to steps from 150 PWM to 170 PWM, from there a linear regression could be made, and from there it is derived that the slope is a =...

    How to Convert Lead Compensator Output to PWM for Hexacopter Height Control?

    Homework Statement Hello, I'm not looking for an answer to my problem, just some hints. Any help would be greatly appreciated. I am required to control a hexacopter, so I'm designing a lead compensator to control the height, it should be able to counteract the pull of gravity. So far I have...

    PI-controller for 1st order system.

    I see what you mean now, and I've done it, it's still a first order system, but that's because the professor told us to set the inductance equal to zero, that actually explains a lot. According to the datasheet it has a small value, and I think that I will use that value instead of zero in order...

    PI-controller for 1st order system.

    Well now I understand the motor model a lot more. It makes sense to move the tachometer to the first summer also! Thanks But I'm not sure what you mean by having the PI controller in series with a second order system, when do we get this second order system? When we calculate the transfer...

    PI-controller for 1st order system.

    Thanks very much for taking your time to help :) Yes, I think so, what we get out in the feedback is the angular velocity. What we are trying to control is the motor speed, we want to set for example 10 rad/s on the input and that should be observed at the output. So what we have is a...

    PI-controller for 1st order system.

    Well it is a dc motor we're controlling. Steady state error should be zero, and settling time quickly as possible. Is there any other method than ensuring phase margin?

    PI-controller for 1st order system.

    Hello, I have an assignment where I have to design a PI-controller for a first order system. The system is given by : G =566.1 / (s +0.3514). I have a slight problem understanding how to deal with this as the Bode plot gives me -90 degrees of phase shift. Usually I would design my...

    Continue EE or change to Physics and Astronomy

    I was in the exact same position as you a year ago. I am currently in an EE program. I always had an interest in astronomy, and was considering to switch. At that point i did enjoy EE, but i absolutely hated digital/analog electronics. It only seemed as if i only really enjoyed the math and...

    How do you tackle professors who only use slides?

    Thanks for all your replies! I'll try to print Them in advance, seems like a really good idea. For those who gave me tips on how to TACKLE the professors, that really made my day lol :D

    How do you tackle professors who only use slides?

    Hi everyone, (dont know if this is the right place to ask) I was wondering if any of you had experience with professors who ONLY use slides, and rarely write on the blackboard. I myself find it quite difficult to note anything down when it is presented on a slide, and sometimes when I look...

    What career path should I choose based on my interests and strengths?

    Tryk to sit down and research the different kind of jobs each one does. I also had many many interests, but settled down with EE. Think hard about what you really want to do the rest of your life, i also recommend to research every subdiscipline that exists in each field
