Discussion Overview

The discussion centers on designing a linear controller for the yaw motion of a hexacopter. Participants explore the necessary equations and transfer functions required for this control design, with a focus on the theoretical aspects of motion and control systems.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant expresses difficulty in deriving the yaw motion equations and seeks assistance.
  • Another participant clarifies that the time constant is represented as t_m, not tau_m*s.
  • Some participants emphasize the need to understand the yawing motion equation and the hexacopter's transfer function to design an effective controller.
  • One participant admits uncertainty about control systems and feedback, indicating a limitation in their ability to assist.

Areas of Agreement / Disagreement

Participants generally agree on the necessity of understanding the yawing motion equation and transfer function, but there is no consensus on how to proceed with the derivation or design.

Contextual Notes

Participants mention the importance of specific equations and transfer functions, but the discussion lacks detailed mathematical formulations or definitions, which may limit clarity on the topic.

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

Of course t_m is the time constant, not tau_m*s
 
Your professor just wrote a first order system which is linear. However, in order to derive a proper you need to know the equation of the yawing motion of your device. Also, you need to know the transfer function of the hexacopter itself. Then you can design the open loop system but to be honest I don't really remember controls and feedback and I don't think I can help you much :(
 
I agree. You have to know the equation of the yawing motion of the device as well as the transfer function of the hexacopter.
