A PURPOSE.

Every mission starts with a real control problem, measurable constraints, and a loop you can inspect from the inside.

Five loops. Five lessons.

Scores use the simulator’s measured response metrics. Adjust the controller, rerun the plant, and watch each constraint respond.

01Starter

Build your first stable loop

Tune a delayed first-order process without trading stability for speed.

  • Overshoot≤ 8%
  • Settling time≤ 9 s
  • Steady-state error≤ 0.03
Start mission
02Intermediate

Reject an unexpected load

A process disturbance arrives after five seconds. Recover without violent actuator movement.

  • Steady-state error≤ 0.04
  • IAE≤ 2.5
  • Controller variation≤ 8
Start mission
03Intermediate

Stop integral windup

The actuator is tightly limited. Recover cleanly from saturation using an anti-windup strategy.

  • Overshoot≤ 12%
  • Saturation time≤ 35%
  • Settling time≤ 13 s
Start mission
04Advanced

Quiet a noisy measurement

Tune a fast loop without letting derivative action amplify sensor noise into the actuator.

  • Overshoot≤ 15%
  • RMS effort≤ 2.5
  • Controller variation≤ 140
Start mission
05Advanced

Tame a dead-time process

Control a sluggish process whose measurement reveals the effect of an action long after it was applied.

  • Overshoot≤ 10%
  • Settling time≤ 20 s
  • IAE≤ 5
