I've set up a PID script that senses the EX-PSL Green Beat note (from the frequency counter) and actuates on the temperature of the end laser to drive the beat note to a given setpoint.
Right now the script only passes the initial sanities checks, that is:
The settings all need to be tuned up - e.g. maximum_increment, hard_stops, time_step, PID constants.
Additionally, the units in the whole thing are pretty useless - some of the channels are in VOLTS, others in WATTS. I'd like to change all these to be in Hz.
EPICS channels added:
