Choose a challenge
Start with proportional control, build toward PI and PID design, or enter an applied engineering lab.
Practice control engineering through interactive challenges.
Tune P, PI, PD, and PID controllers, submit them to the Judge, and learn from measured system responses across classical problems and applied engineering labs.
How it works
Learn control design by doing it.
Tune and simulate
Adjust controller gains and inspect measured rise time, overshoot, settling time, steady-state error, and control effort.
Submit and improve
Use instant Judge feedback to compare attempts, refine your design, and build practical control intuition.
Controller topics
Build from feedback basics to robust PID tuning.
P control
Explore the speed, accuracy, and steady-state trade-offs of proportional feedback.
PI control
Use integral action to remove steady-state error while managing transient response.
PD control
Apply derivative action to improve damping and transient performance.
PID control
Coordinate all three terms across performance, robustness, and actuator constraints.
Applied engineering labs
Connect controller gains to real system behavior.
Move beyond abstract tuning with scenarios based on vehicles, mechanical systems, electric motors, aircraft, suspension, and unstable plants.
