Control Systems Engineer
Designs systems that regulate and automate machines — from cruise control in cars to autopilot in planes.
Did you know?
Airliner autopilots can land a plane by themselves, and in 2020 an Airbus test plane made fully automatic, camera-guided take-offs, a world first.
How subjects help
- Mathematics: Write equations that tell a system how strongly to correct itself when it drifts off target.
- Physics: Understand how a car or plane speeds up and slows down so its controls respond smoothly.
- Computer Science: Program the feedback loop that reads sensors and adjusts motors many times a second.
A famous name
Rudolf E. Kálmán: Co-invented the Kalman filter, used to steer and guide control systems from rockets to phones.
Try it yourself: Measure your sensor delay
- Your helper holds the ruler at the top end. Hold your thumb and finger open just below the bottom end, without touching it.
- Your helper drops it without warning. Catch it as fast as you can and read the number at your fingers.
- Do five drops and write them down. Then try with a "1, 2, 3" countdown, and with your other hand.
- Label your body like a robot: eyes = sensor, brain = controller, hand = motor. Which part of the chain do you think takes longest, and why did the countdown help?
Robotics and control engineers measure how long a machine takes to sense, decide and act, because a slow loop makes a robot overshoot or react too late.
