| SL plan for run 1071211
** MP 517 - Experimental Test of a Kalman Filter for the Vertical Position ** 1) Load from shot 1070406006 2) Reduce current from 0.9MA to 0.6MA 3) Reduce field from 6.2T to 4T 4) Reduce density from nl_04=1e20 to nl_04=0.7e20 5) Push the button OBSERVERS -> New and select dpcs_kalmanfull2_zcur from the menu, then push ADD and Dismiss 6) Push the button OBSERVERS again, the kalman routine should appear in the list. Click on it in order to open the widget 7) Input "[0.8,10.]" in the field "SWITCH_TIMES". Push APPLY, then OK 8) Load into the live tree and run the shot. Tune the programming as needed (meanwhile, SL will monitor the output of the filter on wire 10 to decide if it is operating correctly) Assuming that the filter operates correctly: 9) Push the button OBSERVERS again, the kalman routine will appear in the list. Click on it in order to open the widget 10) Input "3" in the field "WIRES". Push APPLY, then OK (this places the filter in the fast control loop) 11) Run 1-2 shots to verify that the filter is rejecting noise and is not destabilizing the vertical control loop. Assuming that everything is working fine so far: 12) Repeat 1) through 11) after loading shot 1070406015 (k-ramping) 13) If the operation of the filter in the loop seems to reduce the activity on the vertical trace, try to push the elongation further to >=1.9 TOTAL: 5-10 shots.

1071211 SL Run Summary. MP 517, Kalman Filter. Kalman works in-the-loop, but with the default value of the noise variance 16e6(m*A)^2 it introduces a gain x 1.25 that has to be compensated with the wire 3 programming. However, with the noise variance at 4e6(m*A)^2 (and a smaller noise rejection) the filter doesn't introduce gain and runs in the loop with the nominal fast vertical gains. MP 516, deltaZ_max. deltaZ_max showed to be a complicated measurement. With the current method there is no control over the initial kick, which can change the result dramatically for the same delay of the saturated chopper command. In same cases the vertical evolution of the plasma was caught and turned around for different values of the elongation k=1.72,1.76,1.78,1.80. These data will need careful analysis to extract a meaningful metric. |

| Summary
_______ Achieved the objectives of both miniproposals on control. Learnt that the kalman filter works, but with some tricks about getting the gains right. It does not substantially help (or hurt) with control but it does reduce the high frequency noise very substantially. The \Delta z _max experiment was imperfect because the noise level is close to the controllable level. Scorecard

Tune shot setup, try Kalman on wire 10 (not in the loop). k is about 1.7 Kalman seems to work off-line Try Kalman on-line on next shot |
| Dec 11 2007 10:11:30:513AM | 1071211003 | Marco Ferrara | Shot#:003
Try Kalman on wire 3 (in the loop). k is about 1.7 Works, move to higher elongation. |
| Dec 11 2007 10:26:57:550AM | 1071211004 | Marco Ferrara | Shot#:004
Try Kalman on wire 10 (off the loop). Load wires from shot 1070406015 to ramp elongation. Elongation up to 1.75 at 1.3s. Kalman off the loop seems to work. Tweak programming to ramp to higher elongation. Turn Kalman in the loop for next shot. |
| Dec 11 2007 10:40:00:430AM | 1071211005 | Marco Ferrara | Shot#:005
Try Kalman on wire 3 (in the loop). Elongation up to 1.75 Kalman in the loop works. Increase elongation in next shot. |
| Dec 11 2007 10:56:38:953AM | 1071211006 | Marco Ferrara | Shot#:006
Kalman on wire 3 (in the loop). Disrupts at about 1.25s when k is short of 1.8. Looks like a VDE. Remove Kalman in next shot. |
| Dec 11 2007 12:05:39:070PM | 1071211009 | Marco Ferrara | Shot#:009
Kalman back on wire 3 (in the loop). See if disrupts again. This might be because of x 1.25 gain introduced by the Kalman on the vertical oscillations. Disrupts again. On next shot lower the gains of fast vertical control by 25% in order to compensate for the gain of the filter. |
| Dec 11 2007 12:28:30:423PM | 1071211010 | Marco Ferrara | Shot#:010
Kalman on wire 3 (in the loop). Wire 3 P from 4 to 3.2 Wire 3 D from 5 to 4.8 Works. Next shot bring the gains to the original and lower the amount of filtering to 4e6. |

| Dec 11 2007 01:02:40:563PM | 1071211012 | Marco Ferrara | Shot#:012
Kalman on wire 3 (in the loop). Everything like in shot 010, but ramp the elongation more. Disrupts at 1.1s, k=1.8 with low frequency oscillations. Might be because of bug in the Kalman routine (on this one we input the value of the noise variance 16e6)? next one try the same setup, but blank the parameters field in the Kalman routine widget. |
| Dec 11 2007 12:56:49:357PM | 1071211013 | Marco Ferrara | Shot#:013
Kalman on wire 3 (in the loop). Everything like in shot 010, but ramp the elongation more. Still disrupts with low-freq oscillations. Might have to do with the way elongation is being pushed (ZXL programming) Move on to MP 516. |

| Dec 11 2007 03:10:23:673PM | 1071211023 | Ian Hutchinson | Plasma. Just fails to catch +8mm.
Move to 1.15s. Restore at 1.155s. |
| Dec 11 2007 03:26:00:290PM | 1071211024 | Ian Hutchinson | Plasma. Disrupts early because of radiative event. |
| Dec 11 2007 03:39:03:763PM | 1071211025 | Ian Hutchinson | Plasma disrupts at 1.05 sec. This is due to a spurious point in the zcur.
That appears to be operator error. |
| Dec 11 2007 03:52:11:423PM | 1071211026 | Ian Hutchinson | Plasma just fails to catch 11mm.
Repeat. |
| Dec 11 2007 04:00:55:257PM | 1071211027 | Ian Hutchinson | Plasma fails to catch.
Remove the freeze programming. Try for higher elongation. Ramp clearin up to 0 at 1.45s (from -.005). Load. |
| Dec 11 2007 04:13:29:853PM | 1071211028 | Ian Hutchinson | Plasma to rampdown. Nice big oscilations.
clearin to +4mm. Load. |
| Dec 11 2007 04:27:43:500PM | 1071211028 | Ian Hutchinson | Plasma to rampdown. Nice big oscilations.
clearin to +4mm. Load. |
| Dec 11 2007 04:27:45:407PM | 1071211028 | Ian Hutchinson | Plasma to rampdown. Nice big oscilations.
clearin to +4mm. Load. |
| Dec 11 2007 04:27:38:203PM | 1071211029 | Ian Hutchinson | Plasma disrupts at 1.25s.
Install shape control freeze at 1.2s. Restore at 1.205. |
| Dec 11 2007 04:42:29:693PM | 1071211030 | Ian Hutchinson | Plasma disrupts a few ms early.
Freeze to 1.1s, restore 1.05. |
| Dec 11 2007 04:52:58:323PM | 1071211031 | Ian Hutchinson | Plasma
freeze off. D=4.8 P=3.2 Kalman default parameters. Apply to wire 3. |
