I can explain and tune a basic closed-loop controller using target, measurement, error, and corrective action.
POE Unit 3 • Lesson 3.7
Closed-Loop Control and Feedback
Focus question: How does feedback allow an autonomous system to reduce error while the mission is running?

Lesson Targets
What You Will Be Able to Do
Feedback-loop analysis
The analysis correctly calculates error and predicts the controller response.
Activity Flow
How the Lesson Moves
Each step builds the control-systems reasoning needed for today’s deliverable.
1. Set the target
Define the desired position, distance, or orientation.
2. Measure error
Compare the sensor value with the target.
3. Correct and repeat
Command an action that reduces the error without excessive oscillation.
Lesson Interactive
Feedback-loop analysis Practice
Apply the lesson concept to an aerospace rover or VEX ground-support scenario. Use the feedback to correct reasoning before documenting the main deliverable.

Predict the Controller
The sign and size of error determine the direction and urgency of correction.
Today’s Work
Main Deliverable
Closed-Loop Control Diagram
Create one focused engineering artifact that demonstrates today’s learning.
- Label target, measured value, error, controller decision, actuator command, and feedback.
- Trace two iterations showing how the error becomes smaller.
