Mounted miniskirt and removed shell-mounting posts

11:00: start of electromechanical tests

Tests with old configurations (calibrations, FF, etc.)

  • shell setting: OK

  • ramping old gains: OK (check opt_ghost data, a line in the noise spectrum at 1kHz)

  • step responses:
    • 20100915_181502: with standard modal amplitude 6e-7, failed with over-current at the first mode (data removed to save disk)
    • 20100915_182135: with 1/10 of modal amplitude (6e-8): OK. (data removed to save disk)
    • 20100915_183742: back to amplitude 6e-7: OK. To be checked: steady state of low order modes seems to be oscillating: consider reducing proportional gain.

  • noise test
    • 20100915_184939: two actuators have large noise wrt the others 398 (12nm rms) and 484 (6.8nm rms). The other actuators have noise less then 4.5nm rms
    • check with temporal analysis: 398 did not show longer the behavior. Confirmed for 484
    • 20100915_193458: excessive noise at 398 disappeared. 484 still large noise
    • 20100915_193651: same as previous
    • 20100915_193902: same as previous (data dir contains also temporal_analysis.sav)

  • elevation test with shell in rest position (see telemetry data)
    • shell in rest position, elevation 90-0deg. Start 20100915_221000, end 20100915_221055
    • shell in rest position, elevation 0-90deg. Start 20100915_222715, end 20100915_222802
    • act#149 and 150 at 90deg have 48-19um gap (see find touch 20100915_221759)

  • elevation test with shell set (no flattening) (see telemetry data)
    • elevation 90-20deg. Start 20100915_223726 end 20100915_223820: OK
    • elevation 20-90deg. Start 20100915_223943 end 20100915_224009: OK
    • elevation 90-20-90deg several times. Start 20100915_224315 end 20100915_225257: OK

  • elevation test with flattening applied:
    • elevation 90-20deg. Start 20100915_225600 end 20100915_225710: OK
    • elevation 20-90deg. Start 20100915_225754 end 20100915_225830: OK

  • elevation test with step responses:
    • el. 90deg: 20100916_000519: OK (i.e. settling < 1ms) oscillation of low orders always present
    • el. 45deg: 20100916_001212: OK (to be checked mode 350, verify just error in visualization of data)
    • el. 20deg: 20100916_001738: OK (strange behavior of mode 600)
    • el. 20deg, only mode 600 saving all data: 20100916_002433: OK no problem

  • again noise test:
    20100916_002846
    confirmed 484 with large noise (30nm rms this time!)
    20100916_005228
    test after power cycle. same problem (8nm rms)

  • investigation on proportional gain (oscillation in step resp. with low order modes)
    • 20100916_010036: current configuration. gain_in=0.13 N/um, gain_out=0.06N/um (mode #2, ST=0.93) d_out=30Ns/m
    • 20100916_012230: mode #2. gain_in=0.12,gain_out=0.06N/um (ST=0.99)
    • 20100916_012230: mode #2. gain_in=0.10,gain_out=0.06N/um (ST=1.14)
    • 20100916_012230: mode #2. gain_in=0.13,gain_out=0.04N/um (ST=1.04)
    • 20100916_012230: mode #2. gain_in=0.10,gain_out=0.04N/um (ST=1.31)
    • 20100916_012230: mode #2. gain_in=0.13,gain_out=0.06N/um, d_out=33Ns/m (ST=1.03)
    • none of the previous attempts reduced sensitively the oscillation. Restored original configuration.

19:00: dismounting the miniskirt to paint Opticote
