This is an offshoot of this question.
There's a new generation of space suits coming up (Z-series, anything that the Zvezda NPP has up its sleeves), and I wonder at the level of sophistication of control algorithms and circuitry used there. Have there been any articles in space engineering journals on using $H_\infty$ methods to get controllers with guaranteed performance? Logic to work around unexpected failures?
Browsing through the list of spacewalks on Wikipedia, I gather quite a few cases where suits' subsystems failed or underperformed (cooling failures, water/humidity control glitches etc.) which had material impact on EVA length and achieved results. While the root causes might have been in hardware, software/controller algorithms could be improved as well.
