Engineering task brief
Mass-Spring-Damper Engineering Lab
Control the position of a mass connected to a spring and damper. The design must remain accurate when the mass changes and recover from an external force pulse.
- Model
- G(s) = 1 / (s² + 10s + 20)
- Mass
- 1 normalized unit
- Damping
- 10
- Spring stiffness

- Force (N)
- Output
- Position (m)
Mass +20%
Repeat the command with 20% more mass.
External Force Pulse
Reject a 0.2 N force pulse applied from 3 s to 4 s.
Actuator constraint: Applied force must remain between -2500 and 2500 N. Your final delivery includes a controller choice, experiment evidence, multi-scenario validation, and a short design conclusion.
Learning objectives
