Summary Report

Type-A

  • Replaced the SG board for the LVDT drivers with a new board in IY. The oscillator signal became stable. The old board seems to have a break in the circuit.

Type-B

  • For the BS, Terrence and I have been calculating the IP-L sensor correction and blending filters. Terrence had new ideas for updating the calculation of the filters, and it was worth trying. I aim to test the results next week.

Type-Bp

  • For PR3, I added the inter-calibration factor and the BF Damper sensor correction filter. The sensor correction is enabled when the suspension goes through ENGAGE_STRONGDAMP state.

Type-C

Electronics

Control

Schedule

  • Type-A: IP control with ACCs.
  • Type-B/Bp: BS sensor correction and blending.
  • Type-C:
