A perl script/ an medm screen are created for SLOWDC PID control. The gain is not optimized yet. Some debugging might be needed.
The script for SLOW_PID.pl is similar to rcav_PID_2011_01_25.pl. I just changed the channel names for SLOWDC.
The process is C3:PSL-FSS_FAST
The actuator is C3:PSL-FSS_SLOWDC
Setpoint is C3:PSL-FSS_SLOWPID_SETPOINT (set to 0)
and other parameters follow the form of C3:PSL-FSS_SLOWPID_...
The perl scripts can be executed on the sun machine, but the result is abnormal. I tried to adjust P gain,
but for either signs I chose for Kp, SLOWDC seems to rail, instead of being steady at a certain value.
I'll check this later, for now it's not very important, since another loop for SLOWDC is also working, and
we can lock the cavity for a long time without SLOWDC feedback.
note for thermal PID
P -0.9 -0.9
I -0.006 -0.0028
D 0 0
