Which parameters have been used here? What's the scenario? Any changes in
environment while testing? It looks like there are a lot of small integral
wind-up phenomena. You should maybe just decrease the integral coefficient
and don't vary the other parameters, and see what happens. But again, I
would need to know environmental conditions. If your driver reports SNR,
e.g., it may make sense to report it on the graph.
