🔁 Feedback control

Unit 3 · Robot bodies & control · 9 min

Closed-loop control: measure → compare with the target → adjust → measure again. An air conditioner cools when above the set point and stops below it. A line follower drifting left steers a little right, and vice versa. The bigger the error, the bigger the correction: the idea of proportional (P) control.
