  > I don't think robust control actually describes deriving an improvement from perturbing an input. Not really. But using a step input to get info to tune a control system is well known. Eurotherm's auto-tuning system for temperature control was one of the first commercial products to self-tune PID loops that way. It started by setting the control value to 0 and listening to the sensors for a while to get data on sensor noise. Then it set the control value to some large value and watched the sensed value ramp up, being careful not to overshoot the goal. This provided enough data to tune the controller. Simple, but practical. The paper is much more general, but doesn't cover how to do much. One of the references, the one on traffic control, is more interesting.[1] It's about traffic signal control in the presence of disruption. They only did some simulated experiments on one road setup, though. It's hard to tell if that actually works, but it's a reasonable idea with some data behind it.
