Matlab Simulink start
[gfa-lc6-64 ~]
[-bash INSTBASE=/prod]$
cd ~/Documents/prj/SwissFEL/epics_ioc_modules/ESB_MX/matlab
module load matlab/2018a

or start directly: /afs/psi.ch/sys/psi.x86_64_slp6/Programming/matlab/2018a/bin/matlab&
this works also on my linux computers

OLD STUFF
Matlab Simulink up to 11.7.2018
Open and run ESB_stage.m (takes very long to open simulink...)
// default frq: 20 kHz Phase, 5 kHz Servo, 6.25MHz AdcAmp
Values for current loop:
PwmSf-> User MAnual page 245
PwmSf=15134.8909 # =.95*16384. PMAC3-style DSPGATE3 ASIC is being used for the output, the counter moves between +/- 16384. PwmSf is typically set to 95% of 16384
scale = 1 for 2 phase motors
= cos(30)=0.866 for 3 phase motors
Amplifier specs (Power Brick LV User Manual.pdf p.19)
5A_rms continous current
15A_rms peak current
14 bit ADC resolution
2us PWM deadBand
33.85A Maximum ADC Current (corresponds to a DAC Value 32737 ==2^15)
Tested values from IDE:
3 Phase, 1A_rms -> MaxDac=1184.895 = np.sqrt(2)*np.sqrt(3)/2*32767/33.850
3 Phase, 1A_peak -> MaxDac=837.8478 = np.sqrt(3)/2*32767/33.850
A_peak=A_rms*sqrt(2)
np.sqrt(3)/2 because of 3 phase (the coil has not always current)
A_peak is used. (A_rms is more dangerous to burn the motor)
if not kw.has_key('IdCmd'):
kw['IdCmd'] = dirCur*scale
kw['MaxDac'] = peakCur*scale;

Current loop:
-> Monitor idMead, idVolts
idVolts: -32768..32,767 Value that goes to the PWM
out{constant} specifying the output magnitude as a percentage of
the maximum output parameter for the motor: Motor[x].MaxDac.
Motor[1].MaxDac=580.80603
#1out1
-> 1 % of 580.8 -> Motor[1].ServoOut=5.808
-> idVolts= 1500
-> idMeas = 155
