PRM CONTROL AUTHORUTY

Jenne, Chiara.

As a firts test, in preparation for future simulations and measuments with PRCL during ISI differential control, we plotted traces for M1, M2, M3 and open loop gains (in attachment). This is useful to understand if/where flters need to be modified.

The second figure shows the loop diagram we think should work when insertng controbution from PRCL (red part). Two different ways are considered to connect PRCL to ISI, shown in blue and black, and not considered yet in the previous model.
