POE Unit 3 • Lesson 3.2

Control Systems and Mission Logic

Compare timed commands with sensor-based decisions using classroom mission examples.

Lesson Snapshot

Student Objective

I can describe the difference between open-loop and closed-loop control in an aerospace mission.

Main Activity

Compare timed commands with sensor-based decisions using classroom mission examples.

Deliverable

Open-loop vs closed-loop comparison chart

Tools / Materials

Notebook, projector, rover examples, VEX examples

1ProblemUnderstand the challenge and why it matters.

A mission can fail when a system follows commands without checking whether the environment changed. Timed commands are useful, but feedback can make a system more reliable.

2ConceptLearn the engineering idea or skill.

Open-loop systems run commands without using feedback to adjust behavior. Closed-loop systems use sensor feedback to compare actual behavior to a goal and make corrections.

3ApplyUse the skill in a guided task.

Sort example systems into open-loop and closed-loop categories, then explain which type would be safer or more reliable for a mission task.

4DocumentRecord your evidence and decisions.

Complete a comparison chart with examples, advantages, limitations, and one aerospace application for each control type.

5ReviewCheck quality and identify your next step.

Your chart should explain when open-loop control is acceptable and when feedback is needed.
