An interactive browser lab for changing controller settings and seeing how simulated systems respond.

For
People learning control engineering through experiments
Worth noticing
The preview shows a motor target of 120 rad/s and a proportional gain setting, with the trace described as calculated from the lab’s motor model.

Field notes

The homepage lays out a four-step learning sequence: predict a response, change one setting, watch motion and signals, then compare and explain. Its motor material names saturation, load torque, and sensor noise; the cart-pole section points out that balancing the pendulum does not by itself bring the cart home. The site describes its plots and metrics as coming from a documented browser simulation.
