We are testing the margins of stability on a rather complicated feedback control system. In this system, the feedback block contains IIR filters implemented within an FPGA. We had issues with these IIR filters themselves becoming unstable intermittently (while running the main control open or...
We have a set of outlets powered by a GFCI breaker. We plug one surge protector into the outlet and turn the surge protector off. We then start plugging equipment in (the surge protector is still off) and the GFCI breaker trips. We have tried different surge protectors and different outlets...
