How can I Implement a PID controller on an object?

Hello,

Please tell me how to create a PID controller for a rigid body?

For example:

I want to control a 1-D rotational motion of a rigid body by using PID controller along with a given angular trajectory.

Thanks for your help

Sincerely

 

Okay, I know how to do the PID control now, it is a fun thing to do.

 

Hi Jiawei, would you mind giving some pointers or some code examples for how to make the controller? For instance say there is a sphere and I'd like to be able to move it manually? Thanks!
